Semiconductor device

Abstract

A semiconductor device is provided, which has a first long side and a second long side opposite to the first long side. The semiconductor device includes a semiconductor stack, a first lower contact structure, a first mesa contact structure, and a first electrode structure. The semiconductor stack has a lower portion and a mesa portion connected to the lower portion. The first lower contact structure is on the lower portion. The first mesa contact structure is on the mesa portion and includes a first injection part, a first extension part connected to the first injection part, a second injection part separated from the first extension part, and a second extension part connected to the second injection part. The first electrode structure covers a part of the mesa portion and is electrically connected to the first mesa contact structure.
