Abstract:
A semiconductor device including a substrate, a semiconductor layer, and a buffer structure is provided. The semiconductor layer is located on the substrate. The buffer structure is located between the substrate and the semiconductor layer. The buffer structure includes a plurality of first layers and a plurality of second layers. The first layers and the second layers are alternately stacked with a same pitch or different pitches.

Claim (Index 5):
The semiconductor device as claimed in  claim 1 , wherein the buffer structure has a bottom region, a middle region, and a top region, and the number of the first layers at the top region is greater than the number of the first layers at the bottom region, and the number of the first layers at the bottom region is equal to the number of the first layers at the middle region when the first layers and the second layers are alternately stacked with different pitches,\n wherein a sum of thicknesses of the first layers accounts for less than 20% of a total thickness of the buffer structure.
