Title: Insulated-gate electric field effect semiconductor device and its production
Inventor: YAMAZAKI SHUNPEI
IPC: H01L29/786
Filed: 1995-12-22
Abstract: PURPOSE: To reduce the number of masks by matching the boundary between a channel area and a pair of impurity areas with the outer end part of anode oxide film formed on the side of a gate electrode. CONSTITUTION: A semiconductor layer 2 only around a TFT area is patterned in an island shape by using a new photo mask after the layer is formed and before a gate electrode is formed. As a result, the layer 2 hardly exists under the lead wiring part of the gate electrode 8, so that a gate electrode wiring and capacitor may not be constituted. The layer 2 is exposed from the projecting gate part by using the second mask and an anode oxidization film 10 is formed around the side of the electrode 8, then the end part of the source and drain area is matched with the end part of the gate electrode while the ion implanting direction is set to be oblique. Therefore, the film 10 has an insulation property against the electrode wiring and no insulation film is necessitated.  After a metallic film is entirely covered thereon, an electrode 7 is is extended over an insulation film 11 by using the third mask so as to part a source and drain electrode 7. Thus, the title device can be produced by using only two or three masks.

Abstract: PURPOSE: To enable flattening sufficiently smoothly, even in the case of the relatively deep groove-like structures arranged on a semiconductor substrate with a simple method by selectively packing a prepolymer into the groove-like structures and curing the prepolymer, then swelling the prepolymer. CONSTITUTION: The polymer adhesive 14 is packed via a supply reservoir during the V-shaped lead-in of the groove-like structures 14, etched into the semiconductor substrate 10.

Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To minimize that an alarm can not be given when the presence of a worker is to be alarmed or that the alarm is given when alarming is not necessary by mounting a specified dipole antenna on the end surface of a vehicle rear part so that an antenna conductor bar is horizontal to the ground. SOLUTION: A dipole antenna is used as a receiving antenna 7A, and it is mounted on a rear gate 10 which is a metallic end surface vertical to the ground in the rear part of a vehicle so as to be horizontal to the ground. The mounting is performed by use of a proper support member. The length of the receiving antenna 7A is set to the length of 1/2: (λ/2) of the wavelength λ of the radio wave used. The rear gate 10 formed of a metal plate acts also as the reflector of the receiving antenna 7A. The reason of mounting on the metallic end surface vertical to the ground is that the end surface is made to act as the reflector, and the reflecting effect of the reflector is made to appear strongly in the backward horizontal direction.
