Nanosheet transistor with stable structure |
abstract |
Sacrificial gate structures are simultaneously formed in isolation regions that are wider than the sacrificial gate structures formed in the active region. The wider sacrificial gate structures are formed by taking advantage of a smaller lateral etch of p-type silicon than undoped or n-type doped silicon during reactive ion etching. Amorphous or polycrystalline silicon is used as a sacrificial pattern transfer patterning layer in the gate patterning process. The p-type amorphous or polycrystalline silicon increases the sacrificial gate structure length in the isolation region and thus reduces spacing between the sacrificial gate structures in the isolation region. During inner spacer formation, the inner spacers pinch-off all sacrificial gate structures in the isolation region preventing the shallow trench isolation structure to be undercut and thus preventing the collapsing of the sacrificial gate structures in the isolation region. |
