Method for producing chips

A method for manufacturing chips (1, 2), in which at least one diaphragm (11, 12) is produced in the surface layer of a semiconductor substrate (10) spanning a cavity (13). The functionality of the chip (1, 2) is then integrated into the diaphragm (11, 12). In order to separate the chip (1, 2), the...

Summary:A method for manufacturing chips (1, 2), in which at least one diaphragm (11, 12) is produced in the surface layer of a semiconductor substrate (10) spanning a cavity (13). The functionality of the chip (1, 2) is then integrated into the diaphragm (11, 12). In order to separate the chip (1, 2), the diaphragm (11, 12) is detached from the substrate composite. The method according to the present invention is characterized by metal plating of the back of the chip (1, 2) in an electroplating process before the chip is separated.
