Ferroelectric nonvolatile transistor |
abstract |
A method of fabricating a ferroelectric memory transistor using a lithographic process having an alignment tolerance of δ, includes preparing a silicon substrate for construction of a ferroelectric gate unit; implanting boron ions to form a p-well in the substrate; isolating plural device areas on the substrate; forming a FE gate stack surround structure; etching the FE gate stack surround structure to form an opening having a width of L 1 to expose the substrate in a gate region; depositing oxide to a thickness of between about 10 nm to 40 nm over the exposed substrate; forming a FE gate stack over the gate region, wherein the FE gate stack has a width of L 2, wherein L 2 ≧L 1+ 2δ; depositing a first insulating layer over the structure; implanting arsenic or phosphorous ions to form a source region and a drain region; annealing the structure; depositing a second insulating layer; and metallizing the structure. n A ferroelectric memory transistor includes a silicon substrate having a p-well formed therein; a gate region, a source region and a drain region disposed along the upper surface of said substrate; a FE gate stack surround structure having an opening having a width of L 1 located about said gate region; a FE gate stack formed in said FE gate stack surround structure, wherein said FE gate stack has a width of L 2, wherein L 2 ≧L 1 +2δ, wherein δ is the alignment tolerance of the lithographic process. |
