Abstract

Abstract A method for manufacturing a hybrid integrated circuit device comprising a step of forming an Al 2 O 3 layer (22) on a metal substrate (21), a step of forming on the Al 2 O 3 layer (22) a resist layer (23) having a pattern opposite to that of a copper layer (24) which will be formed on the Al 2 O 3 layer (22) by a later step, a step of forming the copper layer (24) on the Af 2 0 3 layer (22) using the resist layer (23) as a mask, a step of impregnating thermosetting material into both the Al 2 O 3 layer (22) and the copper layer (24), and a step of providing at least one semiconductor element (26, 27, 28) on the copper layer (24).
