Patent ID: 10396066

Abstract:
The present application discloses an electro-static discharge (ESD) transistor array apparatus, and relates to the field of semiconductor technologies. The ESD transistor array apparatus may include: a semiconductor substrate, the semiconductor substrate including a semiconductor layer, a doped region on the semiconductor layer, and a substrate contact region, where the doped region and the substrate contact region are isolated, and where the substrate contact region includes at least a first contact region part separately disposed on two sides of the doped region; multiple gates arranged in parallel on the doped region, where a direction of extension of the multiple gates is in parallel with a direction of extension of the first contact region part; and a dissipation layer contact member disposed on each gate along the direction of extension of the gate, where density of the dissipation layer contact member decreases with a decrease in a distance from the gate on which the dissipation layer contact member is located to the first contact region part on a corresponding side. By means of the present disclosure, uniform heat dissipation of an ESD transistor array apparatus can be achieved.
