Abstract:
Methods of forming a compact FDSOI OTP/MTP cell and a compact FinFET OTP/MTP cell and the resulting devices are provided. Embodiments include forming a SOI region or a fin over a BOX layer over a substrate; forming a first and a second gate stack, laterally separated, over respective portions of the SOI region or the fin; forming a first and a second liner along each first and second sidewall and of the first and the second gate stack, respectively, the second sidewall over respective portions of the SOI region or the fin; forming a spacer on each first and second liner; forming a S/D region in the SOI region or the fin between the first and the second gate stack; forming a CA over the S/D region; utilizing each gate of the first gate stack and the second gate stack as a WL; and connecting a BL to the CA.
