Abstract Disclosed herein is a semiconductor device comprising a region in which carriers are transferred in the lamination direction of a multiple quantum well. A multiple quantum well multiplication layer according to the present invention can be found in a superlattice APD device, wherein a superlattice structure with a varying well width is introduced to a hetero- interface present in the transfer region, thereby preventing a pile-up of the carriers.
