Title: Semiconductor stack
Inventor: YAMAMOTO HIROSHI
IPC: H01L23/40
Filed: 1982-03-01
Abstract: PURPOSE:To prevent effectively generation of corona discharge and a crack in the  semiconductor stack by a method wherein shielding electrodes and contractive tubes  are provided on the insulating double-end studs of the semiconductor stack. CONSTITUTION:Both the edges of the shielding electrode 9 consisting of semiconductive  resin applied on the surface of an insulator 5 are made to have the curved surface  shape for increase of the shielding effect. When assembling is to be performed, by  connecting the shielding electrodes 9 and cooling fins 2 with a conductive material, both are made to have electric potential of the same, electric field at the edge part of  the cooling fin 2 is mitigated according to the shielding electrode 9 thereof, and prevention of generation of corona discharge between the insulating double-end stud 3 and  the cooling fin 2 can be attained. Because the semiconductor and contractive tube 10  equipped by heating thereafter on the metal double-and stud 4 has superior adhesion  with the insulator, and has inferior adhesion with the metal, the tube has the effect to  act as the cushion material mitigating residual stress to be generated after injection  molding of the insulator is performed, and even when total length of the insulating  double-end stud 3 is elongated, a crack is hard to generate, and quality thereof is also  stabilized.

Inventor: TSUTSUMI YASUKI
IPC: H01L21/52
Filed: 1987-02-18
Abstract: PURPOSE:To find the occurrence of cracks in a semiconductor chip beforehand, by providing elements for detecting stress. CONSTITUTION:For example, slender piezoelectric elements 3 having a rectangular shape are provided at the sides of semiconductor chip 1 in parallel on a passivation film at the peripheral part of the semiconductor chip 1. When the piezoelectric element 3 is provided at the peripheral part of the semiconductor chip 1, the stress at the peripheral part, where the largest stress tends to yield, can be detected with good sensitivity based on a voltage across both ends. Both ends of the piezoelectric element 3 are connected to the protruding parts of bonding pads 21 and 22 for the piezoelectric element 3 through opening parts, which are provided in the passivation film (not shown in the Figure). Thus the stress in the semiconductor chip 1 can be detected based on the electric output (voltage) of the piezoelectric element 3. In this way the occurrence of cracks in the semiconductor chip 1 can be found at an early stage.

Abstract: PURPOSE:To set a threshold level with high accuracy with a wide bias adjustment width with respect to an input signal with a small logic amplitude by dividing Schottky junction field effect transistors(TRs) for bias adjustment side. CONSTITUTION:Gates of Schottky junction field effect TRs 14, 15 are connected respectively to input terminals 33, 34 and the conduction of the Schottky junction field effect TRs 14, 15 is controlled by a voltage of a bias signal inputted from the terminals and a current i22 flowing to a resistor 22 is controlled.
