Abstract
A semiconductor switch device includes a first semiconductor layer, intrinsic layers, and second semiconductor layers that are stacked. There are at least two intrinsic layers. The second semiconductor layers are in a one-to-one correspondence with the intrinsic layers, and each second semiconductor layer is stacked on a side of a corresponding intrinsic layer away from the first semiconductor layer. The first semiconductor layer forms one PIN diode together with each first intrinsic layer and each second semiconductor layer. Any two adjacent PIN diodes are electrically isolated. Automatic parameter matching between the two PIN diodes is implemented by using a geometrically symmetric figure with centers of the two PIN diodes aligned. In addition, the entire semiconductor switch device has a compact structure.
