Title: Method for washing wafer
Inventor: SHOJI SHIGERU
IPC: B08B3/02
Filed: 1989-03-22
Abstract: PURPOSE:To eliminate trouble such that a stain and irregularity are generated on a metal substrate surface especially in the washing of a wafer after plating treatment by substituting oxygen in pure water with nitrogen to remove the same and spraying this pure water to the surface of the wafer. CONSTITUTION:A nitrogen bubbling apparatus 7 is provided between a pure water tank 6 and a high pressure pump 5. Dissolved oxygen in pure water is substituted with nitrogen using said bubbling apparatus 7 to bring the pure water to an oxygen free state and this pure water is supplied into a pure water feed pipe 3 as pressurized pure water by the high pressure pump to be sprayed to the surface of the wafer 2 rotated by a rotary spinner 1 from a jet nozzle 4. By this method, the contaminate on the surface of the wafer 2 is blown off and, at the same time, the surface of the wafer 2 can be substituted with the pure water to be washed. As a result, it is prevented that the metal substrate surface of the wafer 2 generates oxidation or electrochemical reaction by the effect of dissolved oxygen in pure water and trouble such that a stain or irregularity is generated on the metal substrate surface is eliminated.

Title: Load controller by human body detection
Inventor: YAMAMOTO YASUKO
IPC: G01V8/12
Filed: 1995-03-28
Abstract: PURPOSE: To control a load in a short time from the detection of a human being while preventing malfunction when human body detected sensors and the loads are provided at plural positions. CONSTITUTION: While a human being exists in the detection area of a hot ray sensor 1, a comparator 3 repeatedly generates detecting signals. When the detecting signal is generated from the comparator 3, a timer 4 allows a pulse counter 5 to count the number of detecting signals for a limited interval of a fixed time. When the count value reaches a specified number, a valid signal is inputted from the pulse counter 5 to a control circuit 6. When the valid signal is inputted, the control circuit 6 turns of an illuminating load 9 and simultaneously outputs an interlock signal from an interlock output terminal T1. When the interlock signal is inputted from the outside and the detecting signal is generated within a prescribed time from that time point, the control circuit 6 turns on the illuminating load 9 without counting the number of detecting signals by the pulse counter 5.
