IPC: H04N5/16
Filed: 1994-04-05
Abstract: PURPOSE:To stably perform a clamping operation without detecting a clasping timing for a signal.with periodicity for a video signal, etc. CONSTITUTION:A detecting part 23 detects the peak value that is the minimum value of the output signal of a video amplifier 1 passing a low-pass filter 2.

Abstract: PROBLEM TO BE SOLVED: To form a trench in a desired shape when it is formed in a semiconductor substrate and make a selectivity for an oxide film large in etching and lower the appearance of an etching residue. SOLUTION: At least in a region to correspond to a depth from the surface of a silicon substrate to a bottom face of a trench, the concentration of oxygen in the silicon substrate is set at 1.3×10<18> cm<-3> or below before formation of an oxide film to prevent an oxygen deposit from being generated at the time of formation of the oxide film. To be more specific, the silicon substrate is annealed with hydrogen to lower the concentration of oxygen in the substrate to the above level or below and then the oxide film is formed and patterned and then a trench is formed with halogen gas (for example, Br gas) as a main reaction gas. By this method, the appearance of an etching residue at the time of formation of the trench can be lowered. Or, such a silicon substrate which has the concentration of oxygen 1.3×10<18> cm<-3> or below would be used instead of doing above process.
