Abstract
PURPOSE:To make it possible to recognize the pattern of a chip positively and readily, by laminating an adhesive layer, to which the chip is bonded, on a base material layer and laminating a light diffusing film between the adhesive layer, on which light for detecting the position of the chip is projected, and the base material layer. CONSTITUTION:As a light diffusing film 12, which is provided between a base amaterial layer 11 and an adhesive layer 13, soft plastics, in which projected light is diffused, is used. The lamination can be readily performed by immersing the base material 11 in the fused plastics. In a vacuum sucking apparatus, in which a semiconductor chip 14 is sucked with vacuum, the light is projected under the state the chip is bonded for positioning the semiconductor chip 14. The light is reflected from the surface of the semiconductor chip 14. The light, which has reached a piece of tape 10, is scattered in every direction. The reflected light from the semiconductor chip 14 is inputted into a detecting means by a remarkably large amount, and the outer configuration of the chip 14 becomes clear.
