Abstract:
1. A method for manufacturing IC chips, comprising: forming a thin film integrated circuit including an insulating layer, a plurality of elements and a conductive layer over one surface of a glass substrate; providing a first film over the thin film integrated circuit; providing a second film over the first film; grinding a surface opposite to the one surface of the glass substrate; polishing the surface opposite to the one surface of the glass substrate which has been ground; cutting the glass substrate, the insulating layer, and the first film without cutting the second film so as to form a plurality of IC chips in which the glass substrate, the thin film integrated circuit, and the first film are stacked; expanding the second film so as to form a space between the IC chips; providing a base on the surface opposite to the one surface of the glass substrate of the IC chips; heating the base for adhering the surface opposite to the one surface of the glass substrate of the IC chips to the base; irradiating the second film with light after heating the base for adhering; and separating the IC chips from the second film.
