Abstract
In an embodiment a method for producing a substrate includes forming a green sheet stack including first green sheets and second green sheets, wherein each of the first green sheets and the second green sheets contains a ceramic material as a main component, and wherein the second green sheets further contain a sintering aid in addition to the ceramic material.
Claims20
A method for producing a substrate, the method comprising:
- forming a green sheet stack comprising first green sheets and second green sheets,
- wherein each of the first green sheets and the second green sheets contains a ceramic material as a main component,
- wherein the first green sheets are free from a first sintering aid,
- wherein the second green sheets contain a second sintering aid, and
- wherein the green sheet stack is formed such that each terminating layer of the green sheet stack consists of at least one first green sheet forming the outermost layer of the green sheet stack.
