摘要:
A semiconductor device includes a first semiconductor layer, a second semiconductor layer and a third semiconductor layer. The second semiconductor layer is formed over the first semiconductor layer and includes a recess in a vertical direction towards the first semiconductor layer. The third semiconductor layer is formed in the recess of the second semiconductor layer and includes a seam or void in the recess.
