Claim Text:
1. A method for transferring a chip situated on a transfer foil to a contact substrate, and for establishing contact between the chip and the contact substrate, in which the chip, the back side of which is attached adhesively to a support surface of the transfer foil facing the contact substrate, is charged with laser energy from behind through the transfer foil, and the chip contacts thereof that are arranged opposite a contact surface of the contact substrate are brought into contact with substrate contacts arranged on the contact surface by means of a pressing device from behind through the transfer foil thereby the pressing device deflecting the transfer foil, the contacting of the chip contacts with the substrate contacts being carried out by deflecting the transfer foil, and a thermal bond is created between the chip contacts and the substrate contacts while the foil being in the deflected state.
