IPC: H01L27/10
Filed: 1987-09-24
Abstract: PURPOSE:To prevent a breakdown strength and wiring resistance from decreasing due to the use of an Si3N4 film cell gate by forming the sidewall film of a thick insulating film on the sidewall of a memory cell gate. CONSTITUTION:An isolating thick field SiO2 film 52 is formed in an Si substrate 51, a gate SiO2 film 55, a gate Si3N4 film 54, and a first gate polysilicon film 53 are sequentially formed, and a capacitor 56 is formed by photolithographic etching. Then, an SiO2 film or a PSG film 57 is deposited as an insulating film by a normal pressure CVD method on a whole surface. In this case, the film thickness t1 on the film 52 becomes larger than that t2 on the substrate 51. When the film 57 is so etched as to remove only the film thickness of the t2, an insulating film 62 remains on the film 52, and a sidewall film 63 thicker than the film 53 remains on the sidewall of the film 53. The breakdown strength characteristics of a transfer electrode 68 to be formed in later step and the film 53 are improved due to the remainder of the film 63.

Abstract: PROBLEM TO BE SOLVED: To dispense with external cleaning solution and also dispense with washing waste solution disposal by intermittently tilting a pH measuring tank, and washing out crystal particles accumulated in the tank to the original solution tank together with a sampling solution by use of a two-layer flow. SOLUTION: A pH measuring tank 4 is divided into a liquid receiving part 6 to which a sampling solution is directly introduced, and pH measuring part 7 having a pH meter inserted thereto. Both the parts are allowed to communicate with each other in the bottom part to prevent the waving of the received sampling solution in the pH measuring part 7. The measured sampling solution is circulated to the original solution tank through an spilling outlet 8 by the gravity. The pH measuring device 4 is tilted by use of a tilting device every fixed time, and an ON/OFF valve 3 on the upper end of a pneumatic liquid feed pipe 2 is closed, whereby the two-layer flow of the sampling solution and air is carried into the pH measuring tank 4, and the crystals accumulated in the tank bottom are washed out. The crystals are washed out to the original tank together with the sampling solution.  In removal of the crystals, not an external washing solution but the sampling itself is used.
