Title: Silicon wafer
Inventor: KUSABA TATSUMI
IPC: H01L21/322
Filed: 1990-03-30
Abstract: PURPOSE:To reduce warpage of a wafer while giving it intrinsic gettering by coating the back of a wafer with a CVD film of silicon nitride and then with a polysilicon film. CONSTITUTION:A silicon nitride film, having a compressive stress, is grown on the rear surface of a wafer by low-pressure CVD. A polysilicon film, having a tensile stress, is grown on the nitride film. This structure reduces the total stress and thus decreases warpage. Preferably, the silicon nitride film is 0.05 to 0.1mum thick, and the polysilicon film is 0.5 to 1.5mum thick. The same effect may be obtained when such silicon nitride films and polysilicon films are alternately laminated by low-pressure CVD. The wafer is heat-treated to promote the precipitation of oxygen at an approximately 100mum thick surface region on the rear side of the wafer. Consequently, high-density precipitation takes place, and the IG effect is obtained, resulting in improved gettering.

IPC: H01L21/3205
Filed: 1987-04-08
Abstract: PURPOSE:To improve on device reliability by a method wherein a coating is formed on the surface of a substrate, the coating consists of many a layer whose thickness is smaller than the depth of a trench provided in the substrate, the layer is removed except from inside the trench, and then another layer is deposited. CONSTITUTION:This manufacturing method consists of two stages. In the first stage, a coating 19 is formed of many layers on a semiconductor substrate 18a, and the thickness of each layer is smaller than the depth of a trench 18b provided in the surface. In the second stage, the layer is removed, except from inside the trench 18b. The first and second stages are repeated until the trench 18b is filled up with the coating 19. In this way, the thickness of a layer may be smaller than the depth of the trench 18b and, because a next layer is deposited only after the removal from the device surface of the layer previously deposited, there will be no eaves produced on the brim of the trench 18b attributable to the coating 19. The result is a reliable filling, which means a high- reliability wiring.
