Abstract
The invention relates to a process for producing a metal-ceramic substrate (1), comprising: —providing a ceramic element (10), a metal ply (40) and at least one metal layer (30), —forming an ensemble (18) of the ceramic element (10), the metal ply (40) and the at least one metal layer (30), —forming a gas-tight container (30) surrounding the ceramic element (10), wherein the at least one metal layer (30) is arranged between the ceramic element (10) and the metal ply (40) in the container, and—forming the metal-ceramic substrate (1) by hot isostatic pressing.
Claims15
A method for producing a metal-ceramic substrate (1), comprising:
- providing a ceramic element (10), a metal ply (40), and at least one metal layer (30), wherein both the metal ply and the at least one metal layer are made from copper respectively,
- forming an ensemble (18) of the ceramic element (10), the metal ply (40), and the at least one metal layer (30),
- forming a gas-tight container surrounding the ceramic element (10), wherein the at least one metal layer (30) is arranged between the ceramic element (10) and the metal ply (40) in the container;
- and
- forming the metal-ceramic substrate (1) by hot isostatic pressing, wherein for forming the metal-ceramic substrate (1) between the at least one metal layer and the ceramic element (10), only an active metal layer (15) is arranged without a solder material and wherein the metal layer and the metal ply becomes part of the metallization in the metal ceramic substrate during the hot isostatic pressing.
