摘要:
A semiconductor device structure is provided. The semiconductor device structure includes a substrate. The semiconductor device structure includes a gate stack over the substrate. The gate stack has a first upper portion and a first lower portion, and the first upper portion is wider than the first lower portion. The semiconductor device structure includes a spacer layer surrounding the gate stack. The spacer layer has a second upper portion and a second lower portion. The second upper portion is thinner than the second lower portion.
