が多くなっている。In the process of manufacturing a semiconductor device, when a semiconductor chip is bonded to a lead frame or the like, usually, a paste-like conductive adhesive is first applied to the lead frame or the like, and a scrub is performed while pressing the semiconductor chip thereon. Then glued. However, in the case of an IC card or the like, there is often not enough space for scrubbing, and because the semiconductor chip is thin, the adhesive may crawl onto the upper surface of the chip, and so on. In many cases, a die-bonding tape (also referred to as a die-bonding ribbon) in which the adhesive is formed into a ribbon is used instead of the adhesive and the cut piece is attached to a heated card substrate.

There was a problem that was. If the suction surface and the card substrate are not parallel to each other well, the die bond tape and the card substrate will adhere locally, and wrinkles will occur on the die bond tape in the areas where they do not adhere, which hinders the bonding of the semiconductor chip.

ことで、達成される。According to the present invention, there is provided [1] a suction head having a cylindrical surface as a suction surface, the suction head vacuum suctioning the suction surface and transporting the suction head onto a substrate. The die-bonding tape sticking device is characterized in that the die-bonding tape is pressed against the substrate, and then pressured air is ejected from the suction surface. [2] In the above [1], the vacuum source and the pressured air are used. A suction passage opening to the suction surface of the suction head so as to communicate with one of the vacuum source and the compressed air source via the passage switching means. [3] After the suction head vacuum-sucks the die bond tape on the suction surface and conveys the die bond tape onto the substrate, the vacuum suction is released, and compressed air is jetted from the suction surface to bring the die bond tape into close contact with the substrate.

It is necessary to adjust the device so that the suction head comes into surface contact with the card substrate, but this is a fairly difficult task, and incomplete adjustment is often made.

Can be expected to be adjusted. However, when the die bond tape is pressed against the card substrate by such a suction head, only the narrow band-shaped portion that is pressed is brought into close contact. Therefore, the remaining portion is made to inject pressured air from the air vent opening on the adsorption surface and is brought into close contact with the air pressure. Since the suction head presses the center of the die bond tape in a strip shape and blows pressure air to both sides of the die bond tape, the die bond tape adheres without wrinkles.
