Abstract
A process for producing a chip, comprising the steps of: PA1 attaching an object to be diced on a pressure sensitive adhesive sheet comprising at least one layer of shrinkable film and a pressure sensitive adhesive layer; PA1 dicing the object into chips, and PA1 shrinking the shrinkable film to thereby reduce an area in which the chips are in contact with the pressure sensitive adhesive. In this process, chips of small thickness and large area can easily be picked up without the need to use a thrust needle in the chip pickup step.
