Title: Manufacture of integrated circuit device
Inventor: SHIMOTORI KAZUHIRO
IPC: H01L21/768
Filed: 1979-06-15
Abstract: PURPOSE:To enhance the withstand voltage between polysilicon layers in an integrated circuit device and reduce the parasitic capacity therebetween by employing a substance having extremely slow oxidate speed for a gate insulating film and independently controlling the thickness of an insulating film between the gate oxide film and the layer without particular mask. CONSTITUTION:Isolation oxide films 102 and a gate oxide film 103 are formed on a P-type silicon substrate 101, an Si3N4 film 105 is coated thereon, and a polysilicon gate electrode 106 is selectively formed thereon. Layers 104 are P<+>-type layers. The polysilicon layer 106 is coated with an SiO2 film 107. At this time the Si3N4 film is not almost oxidized. With a mask 107 the Si3N4 film 105 and the SiO2 film 103 are perforated with openings. Since the SiO2 film 107 has sufficiently thicker thickness than the Si3N4 film 103, most of it is not etched and retained. Then, the gate oxide film 108 is coated as oxidized, and the polysilicon gate electrode 109 is selectively formed thereon. Subsequently, an N<+>-type layer 110, SiO2 film 111 and PSG film 112 are formed as the conventional manner thereon, and electrode wires 114 are provided to complete it. This configuration can improve the withstand voltage between the polysilicon layers, reduces the parasitic capacity between the layers, and accelerates the operation of the integrated circuit.

Title: Device for manufacturing semiconductor device
Inventor: HORI KOICHIRO
IPC: H01L29/78
Filed: 1985-04-10
Abstract: PURPOSE:To enable the sure removal of the gas bubbles deposited on a surface of a semiconductor substrate by delivering an impact to the semiconductor substrate present in a solution. CONSTITUTION:A cassette 2 containing a semiconductor substrate 1 is put on a swing table 3 or is fixed to the table freely for detachment and a swing table 3 is moved. The movement applied to the swing table 3 by an impact mechanism 7 accompanies a rapid acceleration and it removes the gas bubbles deposited on a surface of the semiconductor substrate 1 effectively. Though the larger magnitude of impact is advantageous in respect of the removal of gas bubbles, the magnitude is restrained to such an extent that the semiconductor substrate 1 is not damaged by the collision against the cassette 2. Consequently, the removal of the gas bubbles deposited on the surface becomes sure and the irregularity of a wet process can be reduced.

Title: System for estimating transmission time
Inventor: KUMAZAKI KOTARO
Filed: 1985-04-12
Abstract: PURPOSE:To calculate and notify the time necessary for transmission of the information to be transmitted by actually measuring three kinds of time, accumulation, transfer and output, between transmission/reception terminal and file memory. CONSTITUTION:By accumulating M number of transmission original to be sent to a specified terminal 3 in advance in a file memory 4, and by sending originals 12a-13c sequentially from a transmission terminal 2, a relativinal expression is obtained between the time necessary for input, i.e. reading time Ti and the time necessary for output, i.e. printing time To. Namely. To/Ti originals are outputted during Ti from the terminal 2, therefore, after one original is read out, the number of original remaining in the file memory M' are (M-Ti/To) and the time necessary for sending one original T is (Ti+M'To+To). Assuming that Ti/To 1, T=(M+1)To; and when M>>1, T=MTo. This means that the most of the time necessary for transmission T is occupied by the accumulation retaining time, and the time T is depending on the accumulated number of original M at the time of original input.
