Title: Formation of insulating film
Inventor: IIJIMA SHINPEI
IPC: H01L21/31
Filed: 1984-02-22
Abstract: PURPOSE:To improve the manufacturing yield by placing a sample on a sample base of the state that the surface temperature is 150 deg.C or lower, then heating while controlling the oxygen concentration on the surface of the sample, thereby forming an insulating film while suppressing the oxidation of the surface of the sample to be feasibly oxidized. CONSTITUTION:A substrate 2 is placed in the state that a sample base 3 rotating around it own axis and around a drive source 4 is maintained at 150 deg.C or lower. Then, air in a reaction vessel 1 is substituted for N2, and the base 3 is heated by a heat source 15. Reaction gas flow rate is regulated by a control system 6. At this time, the gas is bypassed by a solenoid valve 16 to a bypass pipe 17. When arriving at the prescribed temperature, the valve 16 is opened to feed the reaction gas already regulated at the flow rate into the vessel 1. After an insulating film is formed on the substrate 2, it is again substituted for N2. Thus, even if W feasibly oxidized is disposed on the substrate 2, the manufacturing yield can be improved without oxidation.

Title: Semiconductor device
Inventor: YAMAGUCHI KEN
IPC: H01L27/10
Filed: 1985-02-20
Abstract: PURPOSE:To prevent an excess over a prescribed value of leakage currents even when the density of a dRAM with a groove capacitor is increased, and to attain the further elevation of density by forming specific relationship between a distance between grooves standing opposite to each other and groove width. CONSTITUTION:A plurality of grooves are shaped in a first conduction type semiconductor substrate, and the relationship of WM/WM-M<=3 is formed between a distance WM-M between the grooves standing opposite to each other and groove width WM in a semiconductor memory storage with a MIS structure capacitor constituted to at least one part of the side wall of the groove. Leakage currents standardized while using 3 as a boundary in the ratio WM/WM-M of groove width WM to the distance WM-M between the grooves standing opposite to each other are reduced in a region having a small WM/WM-M. That is, leakage currents IL can be minimized to the same value of WM-M by decreasing WM. Accordingly, the distance WM-M between the groove and the groove can further be reduced, thus further increasing the density of dRAM itself.
