WebThe gate-last HKMG process requires two new CMP processes, both requiring extreme control over final gate height and topography. Because the gate stack is at the heart of the active device, it is far more sensitive to dimensions compared to passive interconnect and isolation structures. WebJul 21, 2024 · The TCAT uses metal CGs, owing to the use of the gate-last fabrication method. Poly-Si channel holes are formed using the punched-through method like that in the BiCS structure; however, a notable difference is that the TCAT is connected to a p-type substrate, which allows the bulk erase operation.
