Patent ID: 8865522

Claim:
A method for connecting a semiconductor chip to a metal layer of a carrier substrate, comprising: providing a semiconductor chip comprising a first side, a second side opposite the first side, a glass substrate bonded to the second side of the semiconductor chip and comprising at least one opening leaving an area of the second side of the semiconductor chip uncovered by the glass substrate, and a metallisation region arranged in the opening of the glass substrate and electrically contacting the second side of the semiconductor chip; providing a carrier substrate comprising a metal layer; bringing an electrically conductive bonding material on at least one of the metal layer of the carrier substrate and the metallisation region in the opening of the glass substrate; placing the semiconductor chip with the bonded glass substrate onto the metal layer of the carrier substrate with the electrically conductive bonding material arranged between the metallisation region and the metal layer; and forming a firm mechanical and electrical connection between the metal layer and the metallisation region through the electrically conductive bonding material.
