Title: Semiconductor device and capacitor device and manufacture thereof
Inventor: OJI YUZURU
IPC: H01L27/04
Filed: 1988-03-09
Abstract: PURPOSE: To obtain a semiconductor device having a capacitor, wherein a highly reliable capacitor insulating film is formed on a polycrystalline silicon film, when a silicon nitride layer is formed on a silicon oxide layer, a part of the thickness of said silicon nitride layer is oxidized, and a silicon oxide layer is formed, by determining the thickness of the silicon nitride layer within a specified range.  
     CONSTITUTION: A silicon nitride film 26 is formed on the surface of polycrystalline cilicon by chemical vapor growth method. Then, a silicon oxide layer 24 is formed on the surface of the polycrystalline silicon when said silicon nitride film 26 is formed. The silicon nitride film 26 is formed on the silicon oxide layer 24 without forming an oxide film any more. Thereafter, the surface of the silicon nitride film 6 is oxidized. At this time, the thickness of the silicon nitride film 26 becomes 18.6nm or less. When the surface of the silicon nitride film is oxidized, the thickness of the remaining silicon nitride film 26 is made to be 3nm or more. Thus the occurrence of local oxidation of a lower polycrystalline silicon electrode 20 is prevented. Therefore, very high reliability can be achieved when the multilayered insulating films are formed on the polycrystalline silicon and a capacitor is formed.

Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To heat a solid food while holding its thickness uniformly by eliminating the shift of the solid food into the axial direction in a rotary drum excepting the time of delivering the solid food. SOLUTION: On the peripheral wall 29 of a rotary drum 9, a stepped part 31 which has delivery guide face 31a oriented into a one rotary direction and extends into a tilted direction with the axial direction, is formed. Further, a delivery aperture 21 which one of the ends of the delivery guide face 31a faces, is provided on one of the end parts of the rotary drum 9. In addition, plural projecting strips mounted facing a direction extending in parallel with the axial direction, are provided on the inner peripheral face 41 of the peripheral wall 29.
