Abstract: Presse de liaison par diffusion (10) et methode pour effectuer la liaison par diffusion par thermo-compression de tampons contraints en cuivre structures (55, 65) directement sur l'une ou chacune des deux surfaces principales opposees (70a, 70b) d'une tranche d'un dispositif semi-conducteur sans substrat (70) ayant un premier revetement metallique (94, 96) de titane, chrome ou nickel et une couche (98, 100) de cuivre, argent ou or. La plaque de support en tungstene ou molybdene couteuse habituellement utilisee pour donner une integrite structurelle a la tranche du dispositif semi-conducteur relativement fragile est ainsi eliminee. La tranche peut avoir une surface des bords exterieurs biseautes passives (70c) avant une liaison. Une partie determinee de chaque tampon contraint en cuivre structure est liee par diffusion sur la tranche du dispositif semi-conducteur tout en soumettant la tranche seulement a une force sensiblement compressive, evitant ainsi la cassure de la tranche pendant le procede de liaison. Les tampons contraints en cuivre structures peuvent avoir des etendues laterales qui ne sont pas superieures a l'etendue laterale de la surface de la tranche du dispositif semi-conducteur qui sont respectivement en contact, permettant le nettoyage et la passivation de la surface biseautee apres la fixation des tampons contraints sur la tranche par liaison par diffusion. Lorsqu'un seul tampon (55 ou 65) est lie sur la tranche, un organe rigide, tel que du quartz peut etre interpose entre la plaque de la presse et la surface non-revetue de la tranche.

Abstract: The composite cover plate for the locking of compartments of electric components, especially for locking the metallic can compartment of an electric condenser consists of an aluminum disc sandwiched between a rubber coating applied on its one side and a disc of artificial material on its opposite side. The disc of artificial material is forced flush against the free surface of the aluminum disc by electric lead-through elements, especially lead-through rivet elements. The rubber coating is disposed around the outer edge of the aluminum disc extending up to a ring-shaped edge portions on the side of the aluminum disc on which the disc of artificial material lies. This ring-shaped rubber coating encloses the outer edge of the disc of artificial material in substantially definite form. Each lead-through rivet is secured against displacement through riveting on the bottom side of the disc of artificial material. Sealing of the lead-through rivet is effected in that the area provided on the head of the rivet is forced onto the surface of the rubber coating through the riveting process. The lead-through rivet is led through an opening in the aluminum disc whose diameter is larger than the diameter of the shaft of the lead-through rivet so that the lead-through element is insulated against the aluminum disc. A burstable valve is provided through a weakening of rubber coating over an opening in the aluminum disc and a coaxial opening in the disc of artificial material.
