ABSTRACT:
A method for the connection of two wafers (11, 12), in which a contact area (15) is formed between the wafers (11, 12) by placing the two wafers one on top of the other, and in which the contact area (15) is heated locally and for a limited time. A wafer arrangement is also described in which two wafers (11, 12) which have been placed one on top of the other and between whose opposite surfaces a contact area (15) is located. The wafers are connected to one another at selected areas (21) of their contact area.
