Abstract
A ceramic substrate manufacturing method is provided in which a copper sheet is etched and then bonded to a ceramic substrate, so that the ceramic substrate has reduced to overall processing time and improved reliability and product lifespan. The ceramic substrate manufacturing method includes the steps of: etching a copper sheet so as to prepare a metal substrate; etching a ceramic substrate so as to prepare a unit ceramic substrate; assembling the metal substrate and the unit ceramic substrate; bonding the metal substrate and the unit ceramic substrate so as to form a stack; partially printing a metal paste on the surface of the stack; and sintering the metal paste.
Claims4
A ceramic substrate manufacturing method, the method comprising:
- preparing metal substrates separated into two or more parts by etching copper sheets;
- preparing a unit ceramic substrate with protruding patterns separated into two or more parts corresponding to a shape of the metal substrates by etching a ceramic substrate including the unit ceramic substrate;
