IPC: H01L21/3205
Filed: 1990-06-06
Abstract: PURPOSE:To prevent a bit line from coming into contact to a node lead-out part by a method wherein the bit is buried in a semiconductor substrate, an oxide film is formed on the periphery of the bit line and the distance between an oxide film and the oxide film on the periphery of the bit line adjacent to the above oxide film is constituted at an interval that a potential directly under an active region is never interrupted from a substrate potential. CONSTITUTION:A groove 20 is formed in the surface of a one conductivity type semiconductor substrate 19 as a bit line 7 formation region in the substrate 19. Then, after an oxide film 21 and an SiN film 22 are formed, the films 22 and 21, which are situated on the surface of the substrate 19 and the bottom of the groove 20, are removed. Then, the bottom of the groove 20 is further dug down using the film 22 as a mask and an oxide film 23 is formed and filled. Then, the film 22, the film 21 under the film 22 and the film 23 in the groove 20 are completely removed to make the substrate 19 expose and an oxide film 24 is formed on the whole surface. By burying a bit line in the substrate, the bit line does not come into contact to a node lead-out part.

These differences are respectively evaluated by relative values and are monitored. The respective boundary values with the short time rise and long time rise in the respective periods of the decision on the abnormality of the furnace conditions are determined according to the levels of the fluctuations in the respective past air permeabilities. The abnormality of the furnace conditions are decided in accordance with these boundary values and the control to the blast furnace operations is started.
