Title: Video signal processing circuit
Inventor: YAMAMOTO YUKIO
IPC: H04N9/68
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a video signal processing circuit that can adjust a burst level of a color signal with a simpler circuit configuration. SOLUTION: A clamp circuit 12 clamps a SYNC chip of an analog composite video signal from an input terminal 10 and gives the resulting signal to a variable gain amplifier 14. The variable gain amplifier 14 amplifies the output of the clamp circuit 12 at a gain corresponding to the detection result of a burst level detection circuit 20 and applies the amplified signal to a BPF 18 via an analog/digital converter 16. The BPF 18 extracts a color signal band component from the output data of the analog/digital converter 16. The burst level detection circuit 20 detects the burst level from the output of the BPF 18 and adjusts the gain of the variable gain amplifier 14 so as to bring the burst kevel to a prescribed value lower than the target. A comb-line filter 22 extracts a color component from the output of the BPF 18.  A sbutractor 24 subtracts the output data of the comb-line filter 22 from the output data if the analog/digital converter 16. The variable gain amplifier 26 amplifies the output data of the comb-line filter 22 so as to bring its burst level to the target according to the detection result by the burst level detection circuit 20.

Title: After-etching treatment method for protecting surface against corrosion characterized by plasma etching
Inventor: YE YAN
IPC: H01L21/3205
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To realize a method of markedly reducing or eliminating surface corrosion of an etched metal-containing feature section. SOLUTION: As a part of an after-etching treatment, before pollutants causing corrosion are removed from the surface, moisture is prevented from being condensed by use of high vacuum, a moisture-free inactive purge gas, and the fact that a substrate is kept at a temperature sufficiently high for water to evaporate. When moisture is condensed on a surface before pollutants which cause corrosion to the etched copper surface are removed, it is important that pollutants located surrounding the etched surface, especially pollutants which may form copper carbonate and/or copper sulfate be prevented from coming into contact with the surface. An after-etching treatment contains a method, where a plasma or a gas which contains at least a reactive hydrogen-containing seed is brought into contact with the etched features.
