Abstract: PURPOSE:To improve element density, by forming transistors in front of semiconductors on an insulating substrate and forming capacitors in the recessed parts of the insulating substrate. CONSTITUTION:While trenches are formed in one surface of a Si substrate 1 or the like, the first polycrystalline Si layer 2 is formed thereon, and every unit consisting of transistors and capacitors is isolated.

Then, after the oxide film 3 on the capacitor parts is then etched and removed, ion implantation of P is performed to reduce the resistance on the capacitor parts of the first polycrystalline Si layer 3 so that N<+> is formed. Successively, the capacitor insulating film 3 is formed on the whole surface and then the second polycrystalline Si layer 4 is grown as a plate electrode on the whole surface, with a photoresist layer 9 being piled thereon to form openings there. Furthermore, the second polycrystalline Si layer 4 is exposed to form a gate oxide film 16 and pile the third polycrystalline Si layer 10 as a gate electrode. Needless parts of the second polycrystalline Si layer 4 are then removed to perform ion implantation of donors into the first polycrystalline Si layer 2 so that source and drain regions are formed, and a SiO2 layer 5 with a pit line 6 piled is formed thereon.

Title: Resistance heating element of graphite
Inventor: MORIMOTO TADAOKI
IPC: H05B3/14
Filed: 1987-07-22
Abstract: PURPOSE:To prevent an alumina protection tube from deterioration and damage and to improve life performance of a graphite heating element by employing a CO gas atmosphere in a heat generator space. CONSTITUTION:Carbon monoxide gas is introduced from an end 14 of a graphite heating element 1 into an inner hole.

Abstract: PURPOSE:To suppress the fluctuation in the voltage of picture element electrodes by capacity coupling so that a sharp image is obtd. by forming an opaque conductive film coated on a drain bus line, gate bus line and thin film transistor via a protective insulating film. CONSTITUTION:The opaque conductive film 7 is formed via the protective insulating film 6 on the drain bus line 2, gate bus line 3 and thin film transistor (TFT) 4 formed on an insulating substrate such as glass substrate 1.

The influence of the potential of the drain bus line 2 on the potential of the picture element electrode 5 is, thereby, extremely minimized. The undesirable fluctuation in the voltages is thereby suppressed and the good image quality is obtd.
