Scanning probe lithography by Hyongsok T Soh ( Book )
7 editions published between 2001 and 2011 in English and held by 138 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 9 WorldCat member libraries worldwide
This report summarizes our progress in development of high resolution acoustic microscopes for use at cryogenic temperatures. During the past year we have concentrated on development of efficient acoustic matching layers for use in liquid helium and extension of our techniques to temperatures below 0.5K in liquid helium. As a first step at these low temperatures, we have begun probing the acoustic properties of the liquid at frequencies at least 5 times higher than previously published results. (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)
Tunneling Acoustic Microscopy by Calvin F Quate ( Book )
4 editions published between 1991 and 1993 in English and held by 4 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
Scanning Tunneling Microscopy of Semiconductor Surfaces ( )
4 editions published between 1990 and 1993 in English and held by 4 WorldCat member libraries worldwide
This is a summary of the results during the first year of a research program aimed at studying the atomic structure of semiconductor surfaces using scanning tunneling microscopy (STM). This research has concerned epitaxial growth of metals on the (111) and the (100) surfaces of silicon, with particular emphasis on the Si(100) surface. We have studied In, Sn, and Sb on Si(100), and Au on Si(111), focusing on phenomena such as order and disorder in surface reconstructions, nucleation and growth, growth anisotropy, and rearrangement of the Si substrate step distribution
Joint Services Electronics Program of the Edward L. Ginzton Laboratory of Stanford University ( Book )
4 editions published between 1985 and 1987 in English and held by 4 WorldCat member libraries worldwide
The central theme of our work at Ginzton is the development of new material and device technologies, along with novel techniques for characterization and measurement, that will allow ultra-high speed electronic and optical processing of information. The different work units of this proposal interconnect the physics and technology of linear and nonlinear optical materials and fibers with new measurement tools which provide unprecedented spatial and temporal resolution. The following paragraphs summarize each of these work units. Professor Bloom's work has been concerned with developing laser techniques for obtaining both time and frequency domain measurements of high speed electrical circuits. The overall objective of Professor Byer's program is the growth, fabrication and characterization of single crystal optical fibers. During the last year and a half Professor Kino has re-directed his efforts from the study of very high frequency acousto-optic taps for optical fibers, to the development of a new type of real-time scanning optical microscope. Professor Quate's work is aimed at developing the technology and studying the applications of the Scanning Tunneling Microscope and the Atomic Force Microscope, both of which allow unprecedented imaging on an atomic scale
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

Research on Cryogenic Vacuum Tunneling ( Book )
2 editions published between 1986 and 1987 in English and held by 2 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

Study of nonlinear acoustics for the purpose of processing "sophisticated signals." by Stanford University ( Book )
2 editions published in 1977 in English and held by 2 WorldCat member libraries worldwide
The work consists of two projects - one on the digital control of acoustic signals from an imaging array and the second on the use of acoustic signals to interrogate thermal images formed on an array of silicon bolometers. In the first project it has been shown that in contrast to the present systems where analog systems are used to control the arrays in acoustic imaging multilevel digital processing systems can be employed to provide for the scanning and focusing of these arrays. The net result is an increase in performance and flexibility of these systems with images in real time. In the second part of the program we have shown that propagating acoustic signals can be used to interrogate an array of silicon bolometers which contain a thermal image. The theoretical and experimental results comprise a foundation for the construction of the thermal imaging device of the type described. The device should outperform existing uncooled thermal imaging devices over a practical range of frequencies. (Author)

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)
