...Omar Dhannoon Jumaah; Yogesh Jaluria Chemical vapor deposition (CVD), which involves chemical reactions in gases for deposition on a heated surface, is an extensively used manufacturing technique for obtaining thin films of materials like silicon, graphene, silicon carbide, aluminum nitride...

... susceptor and flow guide is considered. The focus is on gallium nitride (GaN) thin films. The study shows how the computational model can benefit reactor design. It also presents comparisons between model prediction results and experimental data from a physical, practical, system. Commercially available...

... temperatures. The embedding process described in this paper consists of low temperature laser microdeposition of on-fiber silver thin films followed by nickel electroplating in a steel part. A microscale laser-based direct write (DW) method, called laser-assisted maskless microdeposition (LAMM), is employed...

... at critical locations in metallic structures, which are heavily used in hostile manufacturing environments. This paper presents the study of design, fabrication, and characterization of integrated microring sensors. Various thin film optical materials were studied and single ring resonators were designed...

...Jun Shinozuka; Ali Basti; Toshiyuki Obikawa In order to measure temperature fields on tool face during cutting, a cutting tool with built-in thin film thermocouples (TFTs) has been devised. The TFTs composed of a nickel and nichrome thin films were fabricated on the rake face near the cutting edge...

...Youneng Wang; Hongqiang Chen; Jeffrey W. Kysar; Y. Lawrence Yao Micro-scale laser shock peening ( μ LSP ) can potentially be applied to metallic structures in microdevices to improve fatigue and reliability performance. Copper thin films on a single-crystal silicon substrate are treated by using μ...

.... The thin film was modeled using a polycarbonate rectangular block, which was indented with a metallic half-round wedge that represents the industrial cutter blades. The wedge radius and sample size were selected to scale to the ratio of slitting blade radius and industrial film thickness. A compression...

...Yuwen Zhang, Associate Professor, A parametric study on shape and cross-sectional area of the thin film produced by Laser Chemical Vapor Deposition (LCVD) with a moving laser beam is presented. The problem is formulated in the coordinate system that moves with the laser beam, and, therefore...

...Jionghua Jin; Huairui Guo; Shiyu Zhou This paper presents a supervisory generalized predictive control (GPC) by combining GPC with statistical process control (SPC) for the control of the thin film deposition process. In the supervised GPC, the deposition process is described as an ARMAX model...
