Title: Semiconductor integrated circuit
Inventor: IKEDA RIKIICHI
IPC: H01L21/3205
Filed: 1987-06-03
Abstract: PURPOSE:To reduce the resistance due to a wiring, and stabilize the electric potential of a semiconductor substrate, by connecting a wiring layer which forms a bonding pad, to a diffusion layer formed on a semiconductor substrate just under the wiring layer with a connection hole arranged in an interlayer insulating layer formed on the upper part of the diffusion layer. CONSTITUTION:The title device is constituted of diffusion region 2 formed to make contact with a semiconductor substrate 1, a power source wiring layer 4 formed on the diffusion layer via an interlayer insulating layer 3, and a cover layer 5. The diffusion region 2 and the wiring layer 4 are connected with a connection hole 6. The diffusion layer 2 and the connection hole 6 are arranged just under a bonding pad 7. Therefore, the length of a wiring to connect the diffusion region 2 and the bonding pad 7 is short, and its resistance can be reduced. Thereby, the influence of noise voltage caused by a current flowing in the wiring layer 4 can be reduced, and the electric potential of the semiconductor substrate can be stabilized.

Abstract: PURPOSE:To reduce the thickness of a semiconductor device by forming a recess on a tab corresponding part of a film substrate, securing the upper surface of a pellet in the same plane as the surface of the substrate, wiring it and sealing it with resin. CONSTITUTION:A circuit 11 is formed of copper foil on an extremely thin polyimide film substrate 10. A recess 13 is formed at the tab corresponding position of the substrate 10, and a pellet 12 is secured to the bottom. The recess 13 is formed to be slightly deeper than the pellet 12. The circuit 11 on the substrate 10 is extended to the periphery of the recess 13, and leads 14 are formed. The pellet and the leads 14 are connected via wirings 15, resin 16 is dropped and sealed. Since the upper surface of the pellet 12 is lower than the leads 14, it does not shortcircuit with the upper edge of the pellet even if the loop of the wirings 15 is lower. No deformation occurs at the wirings due to the flow of the resin due to a sealing method with dropping of the resin, the height of the loop can be remarkably reduced, and the resin 16 on the substrate 10 is reduced in thickness, thereby obtaining a thin semiconductor device.
