Title: Manufacture of semiconductor device
Inventor: HIRAGUCHI TAKAO
IPC: H01L21/28
Filed: 1987-11-18
Abstract: PURPOSE:To easily manage the length of an effective channel by removing an insulating layer at the intermediate to an upper polysilicon layer by anisotropically etching when a double polysilicon gate is patterned and formed, ion implanting a substance having an N-type and small diffusion coefficient to the exposed lower polysilicon layer and then removing the lower polysilicon layer by isotropically etching. CONSTITUTION:When a double polysilicon gate is patterned and formed, a resist mask 6 is formed on an upper polysilicon layer 5, and an insulating layer 4 at the intermediate to the layer 5 is removed by anisotropically etching. Then, after a substance having an N-type and small diffusion coefficient is ion- implanted into the exposed region, a lower polysilicon layer 3 is removed by isotropically etching thereby to reduce the etching amount of the lower polysilicon layer covered with the upper polysilicon layer. Thus, the ratio of the width W of the upper polysilicon layer to the width (w) of the lower polysilicon layer becomes near 1, thereby easily managing the length of an effective channel.

Title: Semiconductor memory
Inventor: FUJII TAKEO
IPC: G11C11/409
Filed: 1987-11-17
Abstract: PURPOSE:To speed up an access time and to prevent malfunction by writing data in a memory cell again in the reset period of a semiconductor memory. CONSTITUTION:Potentials of sense nodal points D1' - the inverse of DN' are quickly amplified because of a relatively small floating capacity C11', and for example, one sense nodal point D1' reaches a supply potential Vcc and the inverse of other sense nodal point D1' reaches the earth potential. Thereafter, column switch transistors, for example, QY1 and the inverse of QY1 selected based on address information given from the external at the time of fall of a column address strobe are driven by rise of an internal signal YSW and are turned on, and data of sense nodal points D1' and the inverse of D1' are transferred to a pair of common data lines I/O and the inverse of I/O, and data is outputted from an output terminal Dout through an output circuit 11. Thus, data is written in the memory cell again in the reset period to not only perform the quick operation of the sense amplifier but also shorten the access time, and the occurrence of malfunction is prevented.

Title: Language process program
Inventor: KAWACHINO HIROKO
IPC: G06F9/45
Filed: 1988-11-17
Abstract: PURPOSE:To shorten the useless executing time by optionally continuing or discontinuing a process when a language process program has a specific error or the error occurring frequency exceeds the designated maximum level. CONSTITUTION:It is checked whether the error occurring frequency exceeds the designated maximum level or not. If so, the control is shifted to a program abnormality end processing part 11. If not, it is checked whether the received error number is equal to the designated one or not. If so, the information showing whether the error number designated the continuation or discontinuation of the process is extracted. When the continuation of the process is designated, an error process part 10 performs the post-process or an error and returns the control to an object program production part 4. While the control is returned to the process 11 when the discontinuation of the process is designated. As a result, the useless executing time is eliminated.

Abstract: PURPOSE:To make it possible to eliminate the necessity of an oil seal, by providing a pressure reducing chamber communicated with the suction side of a second stage side pump, in a rotary shaft coupling a first stage side rotor with a second stage side rotor. CONSTITUTION:A pressure reducing chamber 20 communicated with a passage 8 is formed in the intermediate section of a rotary shaft 4 coupling between first and second rotors 2, 3. Leakage gas from a chamber F causes the pressure in the shaft section of a second stage side pump to rise, and therefore, is liable to flow into the first stage side shaft section due to the pressure differential therebetween. However, the leakage gas reaches on its way the pressure reducing chamber 20 which is communicated with an suction side chamber D in the second stage side pump from which the leakage as is sucked and returned by the second stage side pump. Thus, it is possible to eliminate an oil seal used as a shaft seal between the first and second stage side pumps.
