Title: Optical semiconductor integrated circuit device
Inventor: TABATA TERUO
IPC: H01L27/14
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent a photo diode deteriorated in frequency characteristic due to a parasitic capacitance and adjacent photo diodes from malfunctioning by forming a reverse conductivity type epitaxial layer on a semiconductor substrate and dielectric isolation region piercing the epitaxial layer to the substrate. SOLUTION: A p-type semiconductor substrate 11 uses a Si single crystal substrate to mechanically support a semiconductor integrated circuit device. An n-type epitaxial layer 12 is laminated on the substrate 11 and dielectric isolation region 13 is composed of trenches 17 extending from the surface of the epitaxial layer 12 to the substrate 11, wall oxide film 18, and dielectric layer 19. This region 13 perfectly surrounds and isolates island regions 20 which form an optical semiconductor device. Thus, the frequency characteristic can be greatly improved to realize a high speed operation. Mutual interference due to flow-in of carriers generated by isolation at the p-n junction is completely avoided and this contributes to the elevation of the degree of integration.

Title: Bending method for metal tube
Inventor: HORIUCHI YASUSHI
IPC: B21D7/16
Filed: 1986-01-29
Abstract: PURPOSE:To properly heat and to perform a good work for bending with even a small curvature by alternately impressing time-shared, different frequency voltages to a heating coil and varying a ratio of sharing time at the beginning and finishing of the work. CONSTITUTION:Time-shared, different frequency voltages are alternately impressed to a high frequency induction heating coil HC by periods of time of t1 and t2. When the voltages are impressed with a ratio of t1/t2 adjusted, a heating temp. depth (heating depth) necessary for hot plastic deformation is changed. Thus, the sharing time ratio at the beginning of a bending work is gradually varied from a small prescribed value (a shallow heating depth) to a large prescribed value (a deep heating depth) and the sharing time ratio at the finishing of the bending work is gradually varied from a large value to a small value. Thus, a high quality bending are obtained by suitably adjusting the heating condition, even if a small curvature is required.

Abstract: PURPOSE:To detect the amount of positional deviation between a photomask and a wafer by a method wherein a patterning is performed on a wiring using the mask having two transparent regions slightly covering the slit provided on the wafer from the left and right side directions. CONSTITUTION:A metal film 2 is formed on the substrate 1 having a concaved section 21 with the width of about 4 microns and a photoresist 3 is applied thereon.

The photoresist on the concaved section is not exposed by a direct light, but is exposed by a reflected light and the metal film 2, including the concaved section, is left unetched. Then, the existence of continuity between the two pads corresponding to the transparent regions 51' is detected. If there is no continuity, the decision is given that there is a pattern defect caused by the positional deviation between the wafer and the photomask.
