This book was released on 2006-10-11 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-integration of sensors with their associated electronics on a single silicon chip may provide many significant benefits regarding performance, reliability, miniaturization and process simplicity without significantly increasing the total cost. Micromachined Thin-Film Sensors for SOI-CMOS Co-integration covers the challenges and interests and demonstrates the successful co-integration of gas-flow sensors on dielectric membrane, with their associated electronics, in CMOS-SOI technology. We firstly investigate the extraction of residual stress in thin layers and in their stacking and the release, in post-processing, of a 1 μm-thick robust and flat dielectric multilayered membrane using Tetramethyl Ammonium Hydroxide (TMAH) silicon micromachining solution. The optimization of its selectivity towards aluminum is largely demonstrated. The second part focuses on sensors design and characteristics. A novel loop-shape polysilicon microheater is designed and built in a CMOS-SOI standard process. High thermal uniformity, low power consumption and high working temperature are confirmed by extensive measurements. The additional gas flow sensing layers are judiciously chosen and implemented. Measurements in the presence of a nitrogen flow and gas reveal fair sensitivity on a large flow velocity range as well as good response to many gases. Finally, MOS transistors suspended on released dielectric membranes are presented and fully characterized as a concluding demonstrator of the co-integration in SOI technology.

This book was released on 2013-07 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of platinum thin films for application as high temperature resistive sensors. To support NASA Glenn Research Center s high temperature thin film sensor effort, a magnetron sputtering system was installed recently in the GRC Microsystems Fabrication Clean Room Facility. Several samples of platinum films were prepared using various system parameters to establish run conditions. These films were characterized with the intended application of being used as resistive sensing elements, either for temperature or strain measurement. The resistances of several patterned sensors were monitored to document the effect of changes in parameters of deposition and annealing. The parameters were optimized for uniformity and intrinsic strain. The evaporation of platinum via oxidation during annealing over 900 C was documented, and a model for the process developed. The film adhesion was explored on films annealed to 1000 C with various bondcoats on fused quartz and alumina. From this compiled data, a list of optimal parameters and characteristics determined for patterned platinum thin films is given.

Available in PDF, EPUB and Kindle. Book excerpt: The manipulation of cells and microparticles within microfluidic systems using external forces is valuable for many microscale analytical and bioanalytical applications. Acoustofluidics is the ultrasound-based external forcing of microparticles with microfluidic systems. It has gained much interest because it allows for the simple label-free separation of microparticles based on their mechanical properties without affecting the microparticles themselves. Microscale Acoustofluidics provides an introduction to the field providing the background to the fundamental physics including chapters on governing equations in microfluidics and perturbation theory and ultrasound resonances, acoustic radiation force on small particles, continuum mechanics for ultrasonic particle manipulation, and piezoelectricity and application to the excitation of acoustic fields for ultrasonic particle manipulation. The book also provides information on the design and characterization of ultrasonic particle manipulation devices as well as applications in acoustic trapping and immunoassays. Written by leading experts in the field, the book will appeal to postgraduate students and researchers interested in microfluidics and lab-on-a-chip applications.

Abstract: Abstract of thesis entitled A STUDY OF INTERGATED SEMICONDUCTOR THIN-FILM SENSORS ON SiO /Si SUBSTRATE submitted by Bin Li for the degree of Doctor of Philosophy at the University of Hong Kong in April 2001 With the development of the information technology, the need for miniaturized, intelligent and programmable sensors is rapidly increasing. To meet this trend, developing thin-film sensors on silicon substrate is of great importance. In this thesis, two areas are focused on. One is spreading-resistance temperature (SRT) sensor on silicon on insulator (SOI), while the other is the multi-function thin-film microsensor on SiO /Si substrate. Based on the principle of minority-carrier exclusion effect, SRT sensor on bulk Si is intensively studied. Optimizations of structural parameters and processing conditions on thermal characteristics of SRT sensors are carried out. With appropriately small electrode and high substrate doping, bulk SRT sensor can function at temperatures up to 400 C at a low current of 2 mA. ii SRT sensor on SOI is then investigated with emphasis on its resistance versus temperature (R-T), low-temperature and AC characteristics. Moreover, the effect of Si- film thickness on the maximum operating temperature (T ) is simulated and verified by max experiment results. When the silicon film is sufficiently thin, i.e. 0.1 μm, T can be max significantly raised up to 550 C, even at a very low bias current of 1 μA. Measurements under low-temperature or AC condition reveal that SRT sensor behaves like a conventional resistor. A new microsensor consisting of a thin-film resistor and a metal-insulator- semiconductor (MIS) capacitor is developed by depositing perovskite-type thin film on SiO /Si substrate. SrNb Ti O, Ba La TiO and Ba La Nb Ti O chosen as the 2 x 1-x 3 1-x x 3 1-x x y 1-y 3 sensing film present reasonable multi-function sensitivities to light, heat and humidity. Differences in the sensing properties of the films are related to their chemical compositions and grain boundaries. It is hoped that by varying the chemical composition, processing conditions of the film, better performance could be obtained. Finally, the effects of device structure on the sensitivities of perovskite thin-film microsensors are discussed. A new physical model is proposed for humidity-sensitive MIS capacitor with a metal-perovskite-SiO -Si structure. Based on this model, it is deduced that higher sensitivity of thinner film is due to higher porosity of the film. However, thinner film results in lower sensitivity to illumination due to poorer absorption, iii while the film thickness only has minor effects on the thermal sensitivity. The effects of SiO thickness are studied and experimental results demonstrate that an optimal value of 250 A gives rise to good multi-function sensitivities. The dependence of electrical properties of photoresistor on device dimension is investigated. Devices with smaller electrode spacings show reasonably linear I-V characteristics. Moreover, heat treatment in O for an optimal time can increase the photo sensitivity by suppressing dark current. In conclusion, SOI SRT sensors and perovskite-oxide thin-film microsensors are promising candidates for integrated sensor applications.
