Abstract:
A method for fabricating semiconductor device includes the steps of: providing a substrate having a memory region and a logic region; forming a stack structure on the memory region and a gate structure on the logic region; forming a first cap layer on the stack structure and the gate structure; performing an oxidation process to form an oxide layer on the first cap layer; forming a second cap layer on the oxide layer; and removing part of the second cap layer, part of the oxide layer, and part of the first cap layer on the logic region to form a spacer adjacent to the gate structure.

Claim (Index 11):
A semiconductor device, comprising:\n a substrate having a memory region and a logic region; buried gates in the substrate on the memory region; a stacked structure on the buried gates on the memory region, wherein the stacked structure comprises:\n a first semiconductor layer; \n a first metal layer on the first semiconductor layer; and \n a first dielectric layer on the first metal layer; \n a gate structure on the logic region, wherein the gate structure comprises:\n a second semiconductor layer; \n a second metal layer on the second semiconductor layer; and \n a second dielectric layer on the second metal layer; \n a first spacer around the gate structure, wherein the first spacer comprises:\n a first cap layer on the stacked structure and the gate structure; \n an oxide layer on the first cap layer; and \n a second cap layer on the oxide layer.
