Title: Formation of thermal oxide film
Inventor: TANIMOTO SATOSHI
IPC: H01L21/316
Filed: 1989-03-31
Abstract: PURPOSE:To contrive the improvement of the breakdown strength with the elapse of time of a thermal oxide film by a method wherein the thermal oxide film is grown in its initial thickness at a prescribed growth starting temperature in a state that O2 is introduced in a furnace and the thermal oxide film is grown in a necessary thickness at a temperature higher than the growth starting temperature in a state that the O2 and halogen or a halogen compound are mixed in the furnace. CONSTITUTION:An Si substrate 1 with a crystal face exposed at a region 3 is cleaned and thereafter, the substrate 1 is introduced in a furnace in a dry O2-containing atmosphere of 900 deg.C and a thermal oxide film is grown in its initial thickness of 160Angstrom or thereabouts. Then, 3 to 5% of HCl is mixed in the O2 atmosphere, the atmosphere is heated up to 1000 deg.C at the rate of 5 deg.C/ minute to make an oxidation proceed and a desired film thickness is obtained on the region 3. Then, the introduction of O2 and HCl is stopped, dry N2 is introduced, the atmosphere is cooled down at the rate of 4 deg.C/minute, is held constant at 900 deg.C and 45 minutes or thereabouts elapse from the start of temperature drop to take out the substrate. By this constitution, the breakdown strength with the elapse of time of the thermal oxide film is improved and the high reliability of the film is kept in a severe environment.

Title: Horizontal synchronizing signal separation circuit for digital video signal
Inventor: OKUBO HIROBUMI
IPC: H04N5/08
Filed: 1990-03-30
Abstract: PURPOSE:To separate a horizontal synchronizing signal in a short time by detecting a synchronizing signal by outputting the detection pulse of the horizontal synchronizing signal by an edge detecting pulse after exceeding a preset value not assuming the trailing edge of an equalizing pulse in a vertical scan period as the horizontal synchronizing signal. CONSTITUTION:A pulse signal 9 is outputted from a comparator 3 after the count value 8 of a clock 7 exceeds the number of clocks equivalent to the equalizing pulse width of the vertical scan period. Therefore, when the edge detecting pulse 6 is outputted, the same horizontal synchronizing signal as the synchronizing signal decided without being affected by the equalizing pulse is detected and separated. Following that, the detecting pulse 10 for the horizontal synchronizing signal is inputted to a counter 2, and the counted number of clocks is cleared, and the next counting is started, and the next horizontal synchronizing signal is detected. In such a way, the horizontal synchronizing signal of an inputted digital video signal can be discriminated in a short time.
