Title: Manufacture of semiconductor device
Inventor: SATOU NORIAKI
IPC: H01L29/78
Filed: 1982-08-18
Abstract: PURPOSE:To improve the yield and the reliability of an element by smoothly forming a gradient bent at a diffused layer of source and drain regions due to the reduction in As<+> ions implanted on the source and drain regions in the side surface of a gate electrode, thereby preventing the decrease in the withstand voltage due to a punch-through phenomenon and alleviating the production of hot electrons. CONSTITUTION:A PSG film 19 is covered by an ordinary CVD method on the overall surface of a semiconductor substrate 11 which contains a gate electrode 13, and a resist film 20 is covered on the upper surface. This buries a recess formed on the side surface of the film 19 to be flattened, and is necessary to form the PSG film of the desired wedge shape in next steps. Subsequently, an ion etching unit is used, a reaction gas such as trifluoromethane is used to anisotropically etch the films 20, 19 so as to allow a PSG film 21 of wedge shape to remain only on the side surface of the electrode 13. Then, As<+> is implanted in the substrate 11, the surface is flattened, a heat treatment is performed for diffusion, thereby forming a diffused layer which has a smooth gradient as compared with the gradient of the diffused layer of the source and drain regions according to the conventional method.

Title: Gas chromatograph
Inventor: SHIKIMA NOBUYOSHI
IPC: G01N30/54
Filed: 1982-08-23
Abstract: PURPOSE:To enable an analysis under a continuously rising temperature from a low temperature below the room temperature to a high temperature above the room temperature by arranging a column thermostat made up of a low temperature thermostatic cell and a high temperature thermostatic cell while a column is made movable inside between both thereof. CONSTITUTION:A thermostat of a gas chromatograph is made up of a low temperature specialized thermostatic cell 1 and a high temperature thermostatic cell 2 adapted to control the temperature variably to the level above the room temperature. A column 3 is made movable freely inside between both the thermostatic cells 1 and 2. When a sample is injected from a sample injection part 9 with the column 3 held in the low temperature thermostatic cell 1, a low boiling point component in the sample is separated to be detected 10. Then, as the column 3 is moved into the high temperature thermostatic cell 2, the column 3 grows to a high temperature and a high boiling point component in the sample is separated to be detected 10. This enables the analysis of a sample with a wide range of boiling point from low to high under a rising temperature at one time without use of a refrigerant such as liquified carbon dioxide. This temperature-rising analysis can be continued by moving the column 3 into the low temperature thermostatic cell 1.

IPC: H01L21/3205
Filed: 1987-06-12
Abstract: PURPOSE:To prevent the concentration of an impurity between a silicide and silicon from lowering and to obtain the contact resistance of a low resistance value by a method wherein the surface of the silicide is covered with a substance containing an element of the impurity to be doped into silicon under the surface. CONSTITUTION:Polysilicon 40 is doped with boron in order to realize a low resistance value and to reduce a contact resistance value; a doped polysilicon film 60 containing boron is formed on a silicide 50; an oxide film 70 is formed on the film. Because the concentration of an impurity on the surface of the silicide 50 is higher than that of the silicon 40, the impurity is introduced into the silicide film 50 from the film 60 containing the impurity on the silicide film 50 when this assembly is heat-treated. By this setup, the concentration of the impurity at an interface between the silicide 50 and the substratum silicon 40 is not reduced; an increase in the contact resistance value between the silicide 50 and the silicon 40 can be eliminated.
