Patent ID: 7964905

Claim:
A flash memory device, comprising: a. a substrate; b. at least one core stack, wherein the at least one core stack comprises: (1) a tunnel oxide layer on the substrate; (2) a first polysilicon layer on the tunnel oxide layer; (3) an anti-reflective interpoly layer atop and in contact with the first polysilicon layer, said anti-reflective interpoly layer having an index of refraction n and a thickness d and being configured for use with a light having a wavelength λ 1 , such that d is an odd numbered multiple of approximately λ 1 /4n; and (4) a transmissive second polysilicon layer on the anti-reflective interpoly layer; c. at least one source region adjacent to the at least one core stack; and d. at least one drain region adjacent to the at least one core stack.
