Abstract:
1. A method for securing a first an electronic structure to an electronic supporting structure by pressure sintering, the method comprising: a) applying a pastelike layer, comprising a metal powder and a solvent, directly to a first, structured supporting film; b) disposing the electronic structure on said pastelike layer; c) drying said pastelike layer, thereby forming metal chips, on said first, structured supporting film; d) applying a second film, thinner than said first, structured supporting film, to said electronic structure on a side thereof which is opposed to said dried pastelike layer; e) subjecting said first, structured supporting film, said dried pastelike layer, the electronic structure and said second film to pressure, whereby the adhesive force between said dried pastelike layer and the electronic structure becomes greater than the adhesive force between said dried pastelike layer and said first, structured supporting film and causes said metal chips of said dried pastelike layer to adhere at least partly to the electronic structure; f) removing said second film, and the electronic structure with said dried pastelike layer adhering thereto, from said first, structured supporting film; g) applying at least one of the electronic supporting structure and a conductor track to said dried, pastelike layer adhered to the first electronic structure; h) removing said second film from the electronic structure; and i) subjecting said at least one of said conductor track and the electronic supporting structure with the electronic structure and metal chips of said dried pastelike layer disposed therebetween, to pressure, for mutually connecting them by sintering.
