Patent JP-S6477176-A (JP)
Title: Manufacture of semiconductor device
Inventor: SHIBATA SATORU
IPC: H01L21/265
Filed: 1987-09-18
Abstract: PURPOSE:To protect the junction of an electrode-side end and a substrate and thereby to prevent FET quality characteristics, Rs in particular, from deterioration by a method wherein a protecting film is formed on a gate electrode-side wall. CONSTITUTION:An n-type working layer 3 is formed in a GaAs substrate 1. On the GaAs substrate 1, a gate electrode and an n<+> layer 5, for whose formation the gate electrode 4 serves as a mask in ion implantation, are formed. An AlN film 14 is then formed to serve as protection in an annealing process and, thereon, CVD-SiO2 is deposited for the formation of a CVD-SiO2 film 15. Then the entire surface is subjected to RIE using such a gas as CF4. The SiO2 film 15 on the AlN film 14 is retained only on a gate electrode side wall 16 after anisotropic etching in the RIE process. Annealing is accomplished for the activation of the n<+> layer 5. The SiO2 and AlN are removed in a prescribed etching process for the retention of a source electrode 7 and a drain electrode 8 for the construction of a GaAs FET.

Title: Pressure casting device
Inventor: ANDO KATSUHIKO
IPC: B22D17/12
Filed: 1985-10-18
Abstract: PURPOSE:To smooth the operation of a plunger and to decrease casting defects by slidably fitting a pressurizing sleeve to a pouring sleeve and freely slidably fitting the plunger pressed toward a counter to the pressurizing sleeve. CONSTITUTION:A molten metal is admitted from a sprue 46a into the hollow part of the pouring sleeve 44 and is poured into a molten metal storage chamber 50. After the sprue 46a is closed by the pressurizing sleeve 36, the counter 26 is moved toward a cope body 14 by a pressing rod 24. The molten metal flows into a cavity 48 and is packed therein. A pressurizing rod 32 is lowered by the effect of a pressurizing cylinder 30, then the plunger 34 moves along the inside peripheral wall of the pressurizing sleeve 34 and the bottom end thereof bulges into the chamber 50. The molten metal in the cavity 48 is thus pressurized and the formed product structure is made denser. Since the sprue 46a is formed to the inside peripheral wall part of the sleeve 36, the plunger 34 is smoothly slidingly moved.

The 1st liquid crystal layer is subjected to the orientation treatment in such a manner that the liquid crystal is oriented approximately horizontally with the substrate. The liquid crystal molecules are preferentially oriented along this orientation treatment direction. The background color of the cell can, therefore, the made into white or black and the good contrast can be imparted to the cell from the voltage-transmittance characteristic thereof. The unequal colors are thereby hardly generated and the black and white display of the large display capacity is enabled; in addition the light leakage by wavelengths is decreased and, therefore, the cell is usable as an optical shutter for the color display.
