Abstract
In a device for attaching a semiconductor chip ( ) to a chip carrier ( ), thereby producing an electrically conducting connection between contact areas ( ) arranged on a surface of the semiconductor chip ( ) and contact areas ( ) on the chip carrier ( ) by means of an anisotropically conducting film ( ) or an anisotropically conducting paste ( ), a pressure die ( ) is used for the application of the pressure to the chip ( ) with an adjustable pressing force against the chip carrier ( ). A counter-pressure support ( ) accepts the chip carrier ( ) with the semiconductor chip ( ) arranged on it with the interposition of the anisotropically conducting film ( ) or the anisotropically conducting paste ( ). An elastic body ( ) is arranged either between the pressure die ( ) and the semiconductor chip ( ) or between the chip carrier ( ) and the counter-pressure support ( ).
