Abstract:
A method of forming a low-cost and compact hybrid SOI and bulk MTP cell and the resulting devices are provided. Embodiments include forming a bulk region in a SOI wafer; forming an NW in the bulk region and a PW in a remaining SOI region of the SOI wafer; forming first and second pairs of common FG stacks over both of the SOI and bulk regions; forming a first shared N+ RSD between each common FG stack of the first and second pairs in a top Si layer; forming a N+ RSD in the top Si layer of the SOI region on an opposite side of each common FG stack from the first shared N+ RSD; forming a second shared N+ RSD between each common FG stack in the bulk region; and forming a P+ RSD between the first and second pairs in the bulk region.

Claim (Index 1):
A method comprising:\n forming a bulk region in a portion of a silicon on insulator (SOI) wafer; forming an n-type well (NW) in the bulk region in a silicon (Si) substrate of the SOI wafer and a p-type well (PW) in the Si substrate of a remaining SOI region of the SOI wafer; forming a first pair of common floating gate (FG) stacks and a second pair of common FG stacks over both of the SOI region and the bulk region, each common FG stack over a portion of the NW and over and perpendicular to a portion of the PW; forming a first shared N+ raised source/drain (RSD) between each common FG stack of the first pair and the second pair in a top Si layer of the SOI wafer in the SOI region; forming a N+ RSD in the top Si layer of the SOI region on an opposite side of each common FG stack from the first shared N+ RSD; forming a second shared N+ RSD between each common FG stack of the first pair and the second pair in the Si substrate of the bulk region; and forming a P+ RSD between the first pair and the second pair in the Si substrate of the bulk region.
