Abstract: PURPOSE:To reduce Vth while holding excellent writing characteristic by continuously locally changing an impurity concentration in a channel region from a source region to a drain region. CONSTITUTION:A channel is formed of a low concentration channel region 4 and a high concentration channel region 5. In order to read, 5V is applied to a control gate 10, about 1V is applied to an n-type region source 2, and 0V is applied to an n-type region drain 3.

About 12.5V is applied to the gate 10, about 7V is applied to the source 2, and 0V is applied to the drain 3. An avalanche breakdown occurs near the drain 3, and part of electrons of generated high energy are implanted in the gate 8. Since the impurity concentration of the region 5 is optimized for wiring, implanting current to the gate 8 is not reduced.

Abstract: PURPOSE:To facilitate assembly work and to reduce cost by deforming a deformation part intentionally formed larger than a calking part and intercepting an unnecessary luminous flux at the deformation part. CONSTITUTION:After lenses 13, 12 and 11 are incorporated in a lens barrel 1, the calking part 1a is thermally deformed or plastically deformed to be calked and the respective lenses are held and fixed in the lens barrel 1.
