Title: Washing of semiconductor wafer
Inventor: AKIYAMA HIROKI
IPC: H01L21/304
Filed: 1990-02-07
Abstract: PURPOSE:To enable washing to be improved by mounting a swing arm at a lower part of a washing carrier and by operating this swing arm for performing washing while enabling only a wafer which is set to the washing carrier to move up and down and the wafer to be lifted from a contact part with the washing carrier. CONSTITUTION:A swing arm 7 is mounted directly below a central part of a wafer 1 and a swing arm operation mechanism 8 enables the swing arm 7 to move up and down. When the device is driven and washing is initiated, a supersonic oscillator 5 is started and a washing liquid 6 generates a supersonic vibration. Then, in this state, a carrier 2 moves up and down due to operation of a pan 3, thus enabling the wafer 1 to be washed. At this time, the swinging arm 7 starts operation and moves up and down as shown by an arrow. With operation of this swing arm 7, the wafer 1 rises from the bottom surface position of the carrier 2 and the wafer 1 itself moves up and down, thus eliminating washing nonuniformity which is generated at a contact part between the wafer 1 and the carrier 2.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to specify padded digital watermark data by outputting digital watermark data inserted into an MPEG(moving picture expert group) stream together with the MPEG stream. SOLUTION: Data outputted from an digital watermark data padding means 3 are quantized by a quantization means 5. The quantized data are encoded to an MPEG stream by an encoding means 6. The generated MPEG stream is transferred to a medium and a terminal by a transfer means 7 to another medium. Digital watermark data inserted by the means 3 are transferred to a medium and a terminal by a transfer means 8 to another medium together with the manufacturing number or the like of the other medium. When the transfer means 7, 8 transfer data to the same medium, the digital watermark data are also transferred to the medium together with the MPEG stream. Thereby the digital watermark data can simply be managed.

The SOG film 9 is then removed from an isolation film 2 through controlled etching. Top face of a trench is then flattened and a second oxidation resistant film 10 is applied tightly onto the first oxidation resistant film 8. When the second oxidation resistant film 10 on an element region 3 is bored through RIE, the isolation film is not etched because the BOG film 9 and the first oxidation resistant film 8 are present below and thereby steep level difference does not occur. According to the invention, element region is bored with gentle level difference.
