Title: Profile and underlayer selectively control on high aspect ratio contact process
Inventor: OUYANG HUEI
IPC: C23F17/00
Filed: 1999-06-09
Granted: 2001-05-01
Abstract: A method of etching oxide for forming multi-layer contact holes on/or polysilicon gate transistor with silicide nitride cap layer on semiconductor substrate or metallic silicide. These multi-layer contact holes are extended until the metal silicide layer on drain/source or the polysilicon layer under silicide nitride cap layer of the gate. The method consists of a main etching step which introduces C2F6, CO and other carrier gases to etch unmask oxide layer; a secondary step which cleans the residues from main etching by mixture etching gas which has lower pressure in the reaction chamber than the main etching step; and the last step which forms the contact holes by the receipt similar to main etching step.

Title: Compact high resolution panoramic viewing system
Inventor: NALWA VISHVJIT SINGH
IPC: H04N7/18
Filed: 1999-07-13
Granted: 2001-05-28
Abstract: A compact high resolution omnidirectional or panoramic viewer has several cameras with a common virtual optical center. The field of view of each of the cameras is arranged to form a continuous 360 degree view of an area when taken as a whole. The cameras are positioned so that they each view a different reflective surface of a polyhedron such as a pyramid. This results in each camera having a virtual optical center positioned within the pyramid. The cameras may be positioned so that their virtual optical centers are offset from each other. The offsets produce narrow blind regions that remove image distortions received from the edges of the pyramid's reflective surfaces. The reflective pyramids may be stacked base to base or nested within each other to produce a more compact panoramic viewer. Using two or more reflective pyramids in such close proximity permits using many cameras with the same virtual optical center. Using many cameras divides a large viewing area into many smaller areas where an individual camera views each smaller area. Since each camera views a smaller area, increased resolution is provided to the user.

Title: The manufacturing of single layer superabrasive tools by infrared brazing
Inventor: WU SHYI-KAAN
IPC: B23K28/00
Filed: 2000-09-18
Granted: 2001-12-11
Abstract: Infrared brazing is a process of fast heating and brazing specimens by infrared generated from the heated W filament in quartz lamp. Since the infrared can transmit quartz tube and be focused on the specimen, the specimen is locally heated by infrared and the rest part of furnace is not heated in joining process. Therefore, infrared brazing is a highly potential process with the characteristics of rapid heating (high energy efficiency), rapid cooling (quick heat dissipation), and fast process. This patent is made use of infrared brazing to manufacture superabrasive tools with single layer superabrasive materials. The process time of infrared brazing is much less than that of traditional brazing heated by electric resistance furnace. The infrared brazing has predominant advantages on both process time and energy saving. Consequently, the cost of such tools can be reduced by application of this technique due to its higher production efficiency and lower energy consumption.
