Patent abstract

A method is disclosed for producing a ceramic substrate made of base that includes a stack of layers. Each layer in the stack includes a non-sintered ceramic material and a binder. The method includes debinding the layers in a temperature interval of TE1-TE3, where TE1 is a minimum debinding temperature and TE3>TE1, and sintering the layers at a temperature TS, where TS≧TE3. Debinding and sintering are performed in a same furnace, and a temperature T of the base does not fall below TE1 during debinding and sintering.
