Title: Resin-sealed semiconductor device and manufacture thereof
Inventor: KOMATSU KOZO
IPC: H01L23/50
Filed: 1991-11-27
Abstract: PURPOSE:To enhance a sealed body in reliability by a method wherein an IC chip, wires, an island, and inner leads connected together by bonding are covered with insulating film and then sealed with resin. CONSTITUTION:An IC chip 6 is bonded to an island 2 of a lead frame and connected to an inner lead 4 by a wire 8. The surfaces of the island 2, the inner lead 4, the IC chip 6, and the wire 8 are covered with an insulating film 20 through a spray method, and the coated semiconductor device is sealed with molding resin 10 through a transfer molding method. The insulating film 20 enhances the molding resin 10 not only in reliability by absorbing a stress but also in moisture resistance reliability. Furthermore, molding resin can be prevented from separating from a lead frame due to a thermal expansion difference between them, whereby the semiconductor device can be enhanced in reliability. As a bonding wire is also coated with an insulating film, it can be prevented from being short-circuited when molding, and semiconductor devices of this constitution are lessened in fraction defective and enhanced in yield in a manufacturing process.

Abstract: PROBLEM TO BE SOLVED: To pliably cope with the change in a working space and a mounting method by performing the expansion and contraction of an outrigger beam freely in a state of being detachably attached to an outrigger beam supporting member at the sidepiece of a body frame and in a state of being attached with a counterweight. SOLUTION: A pin hole 35 for inserting a connecting pin 65 of a counterweight 60 is opened in the top of an outer cylinder 30. A lower end of this connecting pin 65 is made so as to be accorded with the top of this pin hole 35, and when height of the counterweight 60 is lowered, insomuch that the connecting pin 65 is inserted into the pin hole 35, the counterweight 60 comes into contact with an outer side face of the outer cylinder 30 and supported by a tip part of a support material 66 as the connecting pin 65 and the pin hole 35 are engaged with each other, and thus installation is all over. Since an outrigger beam 40 is set up in a portal spatial part of the counterweight 60, the counterweight 60 once attached is unable to expand or contract the outrigger beam 40 any longer.
