Title: Reactor and control method thereof
Inventor: SHIMIZU TSUTOMU
IPC: H01L21/31
Filed: 1984-12-27
Abstract: PURPOSE:To uniformalize the treatment and improve the yield by a method wherein a reactor is connected with the local exhaust portion by a first and second pipes, and at least the first pipe is provided with a valve and made thicker than the diameter of the second pipe. CONSTITUTION:The connecting pipe 5 of a reactor 1 and the local exhaust portion 4 are connected by pipes 9a, 9b, which have valves 10a, 10b, respectively. The ratio of the opening areas between the pipes 9a, 9b is, for instance, 4:1. At the oxidation or impurity diffusion time, the valve 10a is closed, and the gas in the reactor is exhausted through the pipe 9b. This causes the pressure loss between the reactor and the local exhaust portion to become large, and pressure deviation within the reactor can be controlled to be small, so that the thickness of the oxide film and the concentration distribution of an object to be treated 3 become stable. When the object to be treated enters or exit, both valves are opened, making the pressure loss small. Therefore, the mist adhering to the vicinity of the reactor entrance, which is generated by a reaction product 12 such as P, is forcibly exhausted along with the gas within the reactor, so that the reaction product 12 does not adhere to the surface of the object to be treated.

Title: Memory double writing system
Inventor: ISHIDO TEIICHI
IPC: G11C11/406
Filed: 1989-10-28
Abstract: PURPOSE:To attain the double writing to both working and spare system memories even these two memories perform the refreshing operations independent of each other by providing a circuit to the spare system to write the data into the memory in a cycle except a refresh cycle of the memory. CONSTITUTION:The systems 0 and 1 are used as a working system and a spare system respectively. Thus a memory write signal 7 received from a processor 1 is written to its own system memory 17 after the conflict caused with a refresh signal 13 through a conflict circuit 15. In the same time band, an address and the data are written into a FIFO memory 6. In a spare system, the contents 10 of the memory 6 are read out and written into a spare system memory 18 after the conflict caused with a refresh signal 14. Therefore the spare system includes a circuit which writes the contents 10 into a memory in a cycle except a refresh cycle of the memory 18. As a result, the double write is possible to both systems even when the both system memories are carrying out the refreshing operations independent of each other.
