Title: Diebonding device
Inventor: USADA KAZUO
IPC: H01L21/52
Filed: 1989-03-13
Abstract: PURPOSE:To prevent development of bubbles in a bonding section by providing a rotating mechanism to rotate a die collet which sucks and holds a die and by die-bonding the die after adhesive is uniformly applied to a rear side of the die. CONSTITUTION:A die collet 1 lowers and attracts a die 3 on a die tray 4 in vacuum. The die collet 1 with the die sucked rotates by 180 deg. upward around a rotating axle 2, and brings the die 3 into contact with a surface of a screen mask 5 of a screen printer. Then, successively, adhesive 6 on the mask 5 is stenciled to a rear side of the die 3 with a squeegee 7. The die collet 1 rotates by 180 deg. downward around the rotating axle 2 to set the die 3 onto a die junction surface of a package 8, then, the die collet 1 is depressed by applying a load a little thereto, and the die 3 is bonded to a die bonding section of the package 8 for die bonding. The package 8 is heated in an oven, and the adhesive 6 which bonds the die 3 to the package 8 is hardened to finish a diebonding process. Thereby, an appropriate and uniform film thickness of adhesive without bubbles can be secured.
