Title: Non-volatile semiconductor memory and its operation method
Inventor: IWATA YOSHIHISA
IPC: G11C16/06
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To improve a lifetime of a non-volatile semiconductor memory by performing weak writing, making only a memory cell having large movement in read-disturbe '0' cell, and discovering easily a memory cell having large movement. SOLUTION: A redundant circuit consisting of a second memory cell array 21 and a second row decoder 22 is used for replacing a memory cell with a redundant memory cell when a cell having large movement exists in read- disturb. Week page writing is performed with a shorter pulse than a writing pulse at the time of writing data so that a threshold value of a normal cell is smaller than read-out voltage at the time of reading data. At the time, As a writing speed of a cell having large movement in read-disturb is faster than that of a normal cell, it is made a '0' cell. Next, a cell having large movement can be easily discriminated by verifying whether a '0' cell exists or not.

Abstract: PURPOSE:To strengthen the controllability of etching in the exposure of semiconductor substrates and prevent the characteristics deterioration of electric devices by firstly growing the second material different from the first material which forms a semiconductor substrate and then growing material forming a photoelectric device. CONSTITUTION:Layers forming a photosensitive device 19, those of InxGa1-xAsyP1-y layer 12, N-type InP layer 13 and N-type InxGa1-xAs layer 14 are easily laminated by the liquid-phase epitaxial growth method.

Abstract: PROBLEM TO BE SOLVED: To allow a reflector to make a self-compensation of an alignment deviation by locating a wavelength board so that a fast axis or a slow axis may be matched with a first or a second axis in a flat plane. SOLUTION: A prism 10 has such a structure that a difference between a change in the phase of polarization in an x-axis direction which is a first axis direction in a flat plane vertical to incident light and that in a y-axis direction which is a second axis direction vertical to the x-axis direction may be π. The wavelength board 1 is so structured that the phase of a polarization component in a fast-axis direction is put forward and the phase of a polarization component in a slow-axis direction vertical to the fast axis is put backward by the wavelength board 1 and thereby a difference between a change in the phase given to the fast axis and that given to the slow axis may be 2d=π/2+mπ ('m' is an integer) and is so located that the fast axis or the slow axis may be identical with the x axis or y axis.  By this method, an alignment deviation can be compensated around one axis of a reflector.
