Method of manufacture of ceramic composite wiring structures for semiconductor devices

A method of constructing a composite structure for use with at least one semiconductor device, comprising the steps of:

• providing at least one patterned electrically conductive member to form a portion of an electrical network that will be directly contacted to the at least one semiconductor device;
• forming a predetermined wiring circuit as part of said electrical network, said predetermined wiring circuit comprising a plurality of conductive components, at least in part by bonding terminal points of said conductive components to said at least one patterned electrically conductive member;
• providing at least one thermal conductor to form a portion of a thermal network;
• and
• applying a ceramic or organo-ceramic dielectric material to the composite structure comprising said patterned electrically conductive member, said conductive components and said at least one thermal conductor by forming a direct covalent bond between said conductive components and said dielectric material and between said at least one thermal conductor and said dielectric material, said composite structure being fully encompassed by said dielectric material except for those portions of the composite structure that are to be used to make electrical/thermal contact with objects external to the composite structure.
