Title: Manufacture of semiconductor element
Inventor: TAKAYASHIKI TETSUYA
IPC: H01L21/318
Filed: 1987-08-21
Abstract: PURPOSE:To arrange a nitride film and an oxynitride film continuously in one plane arbitrarily, by forming a nitride film on the whole surface of a semiconductor element, whose metal wiring process has been finished, selectively implanting oxygen ions, and heating and annealing the implanted part. CONSTITUTION:An electrically writable nonvolatile memory (EPROM) is formed on a semiconductor substrate 1. A nitride film 5 is deposited and grown on the entire surface of a semiconductor element, which is formed to a metal wiring 2. After resist 6 is applied, the resist 6 at only the cell part of the EPROM is removed. Oxygen ions are implanted in the nitride film 5. Then, the resist 6 remaining in the surface is removed. Thereafter, the nitride film 5 is selectively heated and annealed by a quick annealing method. Then, the implanted oxygen ions are activated. The nitride film 5 is transformed into an oxynitride film 7. Thus, the nitride film and the oxynitride film are arbitrarily arranged in the same plane.

Abstract: PURPOSE: To effectively prevent duplicate feed of paper sheets in a paper feed device. CONSTITUTION: The paper sheet 26 on a paper feed table 24 is fed toward a paper separation roll 20 by means of a paper feed roll 22. The upper face 29 of a presser member 28 is projected to the paper separation roll 20 side in the section perpendicular to the axis of the paper separation roll 20. The presser member 28 is energized toward the paper separation roll 20 by a spring 30. An elastic pad 32 is sandwiched between the roll 20 and the presser member 28. One end part on the upper stream side in the paper feed direction of the elastic pad 32 is vertically movable and connected to a movable member 50 energized downward.  When the paper sheets 26 are duplicatedly fed between the elastic pad 32 and the roll 20, the separation angle of the elastic pad 32 in the vicinity of the contact part with the roll 20 is gradually reduced as it goes away from the contact part to the upper stream side in the paper sheet carrying direction. The duplicatedly fed paper sheets are obstructed to move in oder from the paper sheet on the lower side by strong resistance as they approach the contact part, and only the uppermost paper sheet is surely separated and carried.
