Scanning probe lithography by Hyongsok T Soh( Book )

7 editions published between 2001 and 2011 in English and held by 126 WorldCat member libraries worldwide

Scanning Probe Lithography (SPL) describes recent advances in the field of scanning probe lithography, a high resolution patterning technique that uses a sharp tip in close proximity to a sample to pattern nanometer-scale features on the sample. SPL is capable of patterning sub-30nm features with nanometer-scale alignment registration. It is a relatively simple, inexpensive, reliable method for patterning nanometer-scale features on various substrates. It has potential applications for nanometer-scale research, for maskless semiconductor lithography, and for photomask patterning. The authors of this book have been key players in this exciting new field. Calvin Quate has been involved since the beginning in the early 1980s and leads the research time that is regarded as the foremost group in this field. Hyongsok Tom Soh and Kathryn Wilder Guarini have been the members of this group who, in the last few years, have brought about remarkable series of advances in SPM lithography. Some of these advances have been in the control of the tip which has allowed the scanning speed to be increased from mum/second to mm/second. Both non-contact and in-contact writing have been demonstrated as has controlled writing of sub-100 nm lines over large steps on the substrate surface. The engineering of a custom-designed MOSFET built into each microcantilever for individual current control is another notable achievement. Micromachined arrays of probes each with individual control have been demonstrated. One of the most intriguing new aspects is the use of directly-grown carbon nanotubes as robust, high-resolution emitters. In this book the authors concisely and authoritatively describe the historical context, the relevant inventions, and the prospects for eventual manufacturing use of this exciting new technology

Acoustic microscopy at cryogenic temperatures by Stanford University( Book )

9 editions published between 1978 and 1984 in English and held by 8 WorldCat member libraries worldwide

We report progress in work on a cryogenic acoustic microscope. Results in liquid argon and nitrogen at about 4300 angstrom wavelength are discussed. Images of gratings and integrated circuits are presented as examples of resolution and contrast. Work on producing effective matching layers to improve acoustic power transfer between solids and helium is summarized. Finally we present images taken in superfluid helium held at 1.95 degrees K.A wavelength of 3600 angstrom was attained, the shortest wavelength ever achieved in an acoustic microscope. (Author)

Electronically focused acoustic imaging device by Stanford University( Book )

6 editions published in 1973 in English and held by 6 WorldCat member libraries worldwide

We describe in this paper a new technique for processing acoustic information from a piezoelectric array. The device we shall describe is capable of presenting dynamic, nearly real time images of acoustic objects whether they be internal body organs in medical applications, wreakage in the sea, or flaws in nondestructive testing. The present device is capable of 1 mm resolution at distances of 20 cm and operates without the use of external focusing element or an intermediary hologram. In the experimental results reported here two dimensional images are obtained using electronic scanning in one dimension and mechanical scanning in the other dimension. We will describe near the end of this paper how a fully electronic two dimensional scan may be implemented. The sensitivity of the imaging apparatus is expected to be sufficient to insure low sound power levels while still obtaining high quality images. (Author)
Acoustic Microscopy for Nondestructive Evaluation of Materials( Book )

5 editions published between 1979 and 1981 in English and held by 5 WorldCat member libraries worldwide

This report covers the results of a research program on acoustic microscopy directed toward the study of integrated circuits and solid materials. This new type of microscopy permits one to examine microscopic features that are unaccessible in the optical microscope. Thus detail beneath metallization layers as well as the grain boundaries in polished samples can be examined without resorting to chemical etching. Adhesion of thin film is a field where acoustic microscopy will play an important role. Photoacoustic imaging is emerging as a key element in the study of thermal properties of materials and some initial results in this area are included. (Author)

Study of Nonlinear Acoustics for the Purpose of Processing Sophisticated Signals by Stanford University( Book )

4 editions published between 1974 and 1977 in English and held by 4 WorldCat member libraries worldwide

The nonlinear interaction between two surface acoustic waves can be used in a number of signal processing devices. In this report the principles which underlie this interaction are developed both theoretically and experimentally. In the signal processing devices it is demonstrated that both convolution and fourier transformations can be carried out in real time. In the imaging work it is shown that acoustic surface waves can be used to scan optical images which are projected onto a semiconducting layer of silicon. This scanning process transfers spatial image pattern into a temporal pattern which can be transmitted electrically to a remote display station. (Modified author abstract)

The coupled modes of acoustic waves and drifting carriers in piezoelectric crystals by Kjell Blötekjaer( Book )

2 editions published in 1963 in English and held by 3 WorldCat member libraries worldwide

The amplification of acoustic waves in piezoelectric semiconductors is analyzed in terms of the normal modes of the uncoupled system. The characteristics of the growing wave are presented for a range of the crystal parameters in terms of the conduction frequency and the diffusion frequency. Boundary conditions are worked out to show that an acoustic wave at the input to the amplifying section will couple into the growing wave without appreciable initial loss. The experimental results with CdS at 600 Mc confirm the general features of the theory and serve to point out two problems which must be overcome. The first is one of coupling into the acoustic waves from an external source. Present methods are quite inefficient. The second is one of internal oscillations within the crystal which occur when the drift velocity exceeds the velocity of sound. If these problems can be overcome, it should be possible to use this gain mechanism well into the microwave region
Tunneling Acoustic Microscopy by Calvin F Quate( Book )

4 editions published between 1991 and 1993 in English and held by 3 WorldCat member libraries worldwide

We have integrated silicon micromachining techniques with piezoelectric thin film deposition to make a near-field acoustic microscope. A piezoelectric zinc oxide (ZnO) transducer is deposited on a substrate of 7740 glass. A sharp tip is formed in a silicon wafer which is anodically bonded to the glass substrate. A sample is attached to substrate of glass with a receiving ZnO transducer. The transducer on the tip excites an ultrasonic beam which passes from the tip to the sample and is detected by the receiving transducer. A feedback signal is generated to keep the transmitted amplitude constant as a sample is raster scanned. The feedback signal is applied to a tube scanner and is also used to modulate the intensity of a display monitor. We find that the instrument has a vertical height sensitivity of about 20 Angstroms and a lateral resolution of better than 800 Angstroms
Research on Cryogenic Vacuum Tunneling( Book )

3 editions published between 1986 and 1987 in English and held by 3 WorldCat member libraries worldwide

The Scanning Tunneling Microscope has been immersed in liquid helium and used to image the surface of graphite with atomic resolution. The instrument has been reduced in size and this makes it possible to scan at high rates and to operate without a system for vibration isolation. It has been possible to record the phonon spectrum of graphite and the vibrational spectra of sorbic acid using the miniaturized instrument. Keywords: Cryogenic; Tube scanner; Graphite; Phonon spectra; Vacuum tunneling; Real time imaging

Scanning Tunneling Microscopy of Semiconductor Surfaces( Book )

5 editions published between 1988 and 1993 in English and held by 2 WorldCat member libraries worldwide

This research program is aimed at studying the atomic structure of semiconductor surfaces using scanning tunneling microscopy (STM). Extensive work has been carried out on the behavior of both indium and gallium on the (111) and the (100) surfaces of silicon. The STM images provide new structural information on all of the metal-induced surface reconstructions observed in these systems. The STM has been particularly applicable to the study of multi-phase surfaces, localized defects, local metal segregation, all of which arise during the growth of a metal on a semiconductor, and can play an important role in the properties of the surface. Information on such spatially localized features (Sub-100 A) is inaccessible by other means. Some preliminary studies of the InP (110) surface have been done. It is anticipated that the the primary thrust of the research will shift to compound semiconductor surfaces during the coming year. Keywords: Atomic structure; Semiconductor surfaces; Silicon; Indium; Gallium; Scanning tunneling microscopy. (JHD)
Sub-Micron Lithography with the Atomic Force Microscope( Book )

4 editions published between 1998 and 2000 in English and held by 2 WorldCat member libraries worldwide

This was a year or progress where we consolidated our gains with parallel arrays of cantilevers, fabricating operating devices (pMOSFETs) using scanning probes as the lithography tool and for in-depth studies of the response of E-beam resist when exposed with electrons from the scanning tips. Our report is divided as follows: (1) High speed atomic force microcopy with parallel arrays of cantilevers; (2) Fabrication of pMOSFET's with SPL Lithography; and (3) Lithography with Hybrid AFM/STM Probes
Advances in mechanically scanned acoustic microscopy by Stanford University( Book )

2 editions published in 1975 in English and held by 2 WorldCat member libraries worldwide

A scanning acoustic microscope, using the design we have previously described, can now be routinely operated at a frequency of 1 GHz with a corresponding resolution of nearly 1 micron. Operating in transmission a number of biological samples have been imaged. With this high resolution, variations in the elastic properties within individual cells can be seen. Moreover, clear distinctions have been demonstrated between the acoustic images and corresponding optical micrographs. Several alternative imaging modes have also been demonstrated with this instrument. One of these is a phase contrast technique in which the phase of the output signal is compared directly to the phase of the input signal. Another mode is reflection imaging which allows specimens on thick substrates to be viewed. This technique has been applied profitably to an investigation of integrated circuits. (Author)
