Title: Manufacture of semiconductor device
Inventor: FUJIMURA SHUZO
IPC: H01L21/306
Filed: 1987-10-15
Abstract: PURPOSE:To reduce a residue separated from a resist, which residue is left behind on a substrate, by removing inorganic contaminant adhering to a resist layer surface during ion implantation by etching the contaminant and removing the resist layer by destroying the same with irradiation of a plasma. CONSTITUTION:Upon removal of a resist layer 2 employed as a mask during ion implantation, inorganic contaminant 4 adhering to the surface of the resist layer 2 during the ion 5 implantation is removed by etching. That is, the inorganic contaminant primarily includes Al and Al2O3, etc., and hence it can be removable by treating with an alkaline solution. Other impurities such as the left organic fraction of the resist layer 3, carbide thereof, and B and As implanted into the resist layer 2 are decomposed into volatile components by irradiation of a plasma 6, and removed. Hereby, residues separated from the resist can be reduced, thereby improving the yield in the manufacture of a semiconductor device such as ICs and the like.

The temp. of the molten metal having the lowered temp. rises and the heat insulating property of the riser is enhanced. The gases in the riser emit outside by passing the through-hole 4 and vent hole 11 without generating blowholes. The exothermic core 2 is preferably a molding consisting of a mixture composed of an exothermic material compounded with Al, ferrosilicon, calcium silicide, manganese dioxide, iron oxide, silica sand, etc., and materials, such as potassium nitrate, sodium nitrate and potassium chlorate, which accelerate combustion and lower the firing temp.

Abstract: PROBLEM TO BE SOLVED: To directly form an extended part on the end of a product by immersing the end in a molten pool of an alloy and pulling the end up at speed enough to form the extended part. SOLUTION: An Ni base superalloy material is put in a water cooled copper crucible installed in an operation chamber that can be filled with argon gas and then, the chamber is filled with argon gas, the superalloy is molten in the crucible. In order to immerse, hold and pull up the product, it is arranged in a holding means. A driving means is connected to a control means, which contains a computer controller for controlling the depth of insetting the extension end of the product into the molten material, holding time and pulling-up speed. With a rotor blade lowered into the molten pool, the inserted part of the blade is remelted through an interaction with the molten metal. The rotor blade also functions as a seed crystal for orientation growth for the purpose of solidifying the extended part from the molten superalloy.  Then, the rotor blade is pulled up by moving it upward at a prescribed speed. Thus, the extended part is solidified that is provided with the same polycrystal unidirectional sulidification crystal structure as the rotor blade.

Filed: 1989-10-06
Abstract: PURPOSE:To decrease the standby current of a memory cell by using a circuit to lower the standby voltage of the memory cell. CONSTITUTION:At the cell when a non-select CS1 signal is in the standby state of the HI level, PMOS Tr T2 is turned OFF, and the HI level Vcc is supplied from the CS1 signal to the gate of NMOS Tr T1. But when the potential differ ence between the gate and point A becomes the threshold voltage VT or below of the NMOS Tr T1, the NMOS Tr T1 is turned OFF so that the voltage VB of the point A reaches the equilibrium state at VB=Vcc-VT. Consequently, at the standby time the potential VB of the point A is lowered to Vcc-VT. In such a manner, the decrease of the standby current is contrived.

Title: Semiconductor memory
Inventor: SHIOMI TORU
IPC: H01L27/10
Filed: 1985-11-20
Abstract: PURPOSE:To operate a semiconductor memory at high speed and to improve the reliability by decreasing the thickness of an N<-> type epitaxial layer only in a memory cell to increase a junction capacity between the base and the collector of the cell. CONSTITUTION:When an N<+> type buried layer 2 is formed on a P<-> type substrate 1, an N<-> type epitaxial layer 3 is formed thereon, a peripheral circuit S is masked with a resist, and only a memory cell M is selectively oxidized and etched, the thickness of the layer 3 can be reduced as compared with the circuit S. Thus, when an N-type impurity is floated from the layer 2, a junction capacity between the base 6c and the collector 6a of a memory cell M increases to endure against information inversion of the memory cell due to alpha-ray to provide high reliability. It can also prevent the margin of the width of the cell from decreasing, provide high resistance against a software error, and operate at high speed. Since the N<-> type epitaxial layer of the circuit S is thick, a junction capacity between the base and the collector decreases to operate at high speed.
