Title: Writing/rewriting method for nonvolatile memory
Inventor: HAYASHI YUTAKA
IPC: H01L29/792
Filed: 1980-03-03
Abstract: PURPOSE: To make both write and rewrite available for information by constituting a gate electrode of FET for memory in two layers through an insulating film.  
     CONSTITUTION: A drain domain 25 and a source domain 26 of reverse-conductive type are diffused and formed on a monoconductive semiconductor substrate 24, and then the first gate electrode 28 consisting of a poly-crystal Si is formed through a thin gate SiO 2  film 22 to come on a channel domain 30 on the surface of the substrate 24 surrounded by those domains. Next, the electrode 28 is surrounded by a thick SiO 2  film circumferentially, and the second gate electrode 23 also consisting of poly-crystal Si is provided through an SiO 2  film 27 to come on the electrode 28. Then, a depletion layer 29 is produced in the substrate 24 right beneath the domain 25 and also a pinch-off domain 31 is produced at the end of the domain 25. Thus a carrier supplied to the channel domain 30 is turned to a hot carrier by a high field of the substrate 24, which is allowed to cross an energy barrier between the substrate 24 and the films 22 and 27 to operate for write and rewrite.

Filed: 1985-02-15
Abstract: PURPOSE:To enable to linearly polarize in an oblique direction of 45 deg. with a simple and inexpensive laser oscillator by forming the optical axis position on a perpendicular section to the longitudinal direction of a laser light axis at a vertex of a right triangle and arranging in a zigzag state to horizontally or vertically. CONSTITUTION:A laser light path is folded in the sequence of polarizing mirrors 4d, 4c, 4b, 4a to emit a light from an output mirror 1. Resonance light axes A, B, C are disposed so that the position of the B-axis is disposed to form a vertex of a right isosceles triangle with A- and C-axis. The polarizing directions of a laser light emitted from an oscillator formed in this manner are the direction designated by an arrow (a) and a direction for connecting B and C. When the polarizing direction is the direction of the arrow (a), if the reflectivity of the polarizing direction (a) of the mirrors 4a, 4b is set to that slightly exceeding those of the mirrors 4c, 4d, the polarizing direction can be unitarily set from the interference possibility of the resonance light. Accordingly, a laser light polarized in the oblique direction of 45 deg. is emitted with respect to the mounting direction from the mirror 1.
