Title: Film piece pasting apparatus and manufacture of semiconductor device using it
Inventor: MITARAI TADASHI
IPC: H01L21/52
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of defective die bonding by preventing a bubble from being confined when a resin film stripe is pasted to a lead frame. SOLUTION: In a film piece pasting collet 1 for chucking and carrying a resin film stripe 4 and pasting it to the island 3a of a preheated lead frame 3, the film piece chucking part 6 is made of a heat resistant rubber member and a groove 6c intersecting a chuck/exhaust gas hole 6b is made in the suction face 6a continuously to the edge thereof. Since the resin film stripe 4 is chucked softly to retard deformation due to suction, entire surface of the resin film stripe 4 can be pressed even if the parallelism between the suction face 6a and the island 3a is insufficient. Consequently, a bubble is prevented from being confined between the island 3a and the resin film stripe 4.

Abstract: PURPOSE:To reduce the increase of a chip area by providing a means which multiplexes and gives syndromes received from plural syndrome forming circuits onto signal lines wired in common. CONSTITUTION:Signal control parts SCA and SCB are provided to transmission type exclusive OR circuits TMA1 and TMB1. Thus the signal lines can be shared for check bit signals p1-p5 and p6-p10 and syndrome signals s1-s5 and s6-s10 respectively. In other words, the wiring areas are limited to a common signal line CSL only and therefore buffer circuits are limited to a common buffer circuit CBF only. Furthermore, the input/output lines of an inverting circuit are limited to a common inverting circuit CIV and its input/output line only. As a result, a semiconductor memory has a comparatively small chip area.
