Patent ID: 7776626

Claim:
A method of manufacturing a semiconductor integrated circuit device, comprising the steps of; (a) preparing a semiconductor wafer which is demarcated in a plurality of chip areas, in which a semiconductor integrated circuit is formed in each of the chip areas, and over which a plurality of first electrodes electrically connected with the semiconductor integrated circuit are formed over a main surface; (b) preparing a first card including a first wiring substrate in which a first wiring is formed, a first sheet which is held at the first wiring substrate, in which a plurality of contact terminals for making contact with the first electrodes and a second wiring which electrically connects with the contact terminals are formed, and with which the second wiring electrically connects with the first wiring, and a tip of the contact terminals faces a main surface of the semiconductor wafer, an adhesion ring which spaces out and holds a first region in which the contact terminals are formed in the first sheet from the first wiring substrate, an extrusion mechanism which extrudes the first region in the first sheet from a back surface side, a plunger mechanism which travels to and pushes with a thrust on the extrusion mechanism so as to extend the first sheet, and a pressurizing mechanism which controls an amount of contact pressurization of the contact terminals on the first electrodes by acting on the extrusion mechanism at a time of contacting the tip of the contact terminals to the first electrodes wherein a lower surface of the adhesion ring contacts the first sheet, wherein the extrusion mechanism, the adhesion ring, and the plunger mechanism constitute one mechanism by fixation, wherein the pressurizing mechanism is disposed over the adhesion ring such that the thrust transmitted to the first sheet is controlled by a strength of the pressurizing mechanism; and (c) conducting an electric test of the semiconductor integrated circuit by contacting the tip of the contact terminals to the first electrodes; wherein an extrusion amount of the first region by the extrusion mechanism and the amount of contact pressurization by the pressurizing mechanism are controlled independently, respectively.
