  • Production of resistor from insulating material by local heating
    Patent number: 4584456
    Abstract: A resistor is formed by locally heating an insulating material layer between conductors to convert the heated material into a first resistor element. A second resistor element is formed to contact the first resistor element while measuring the resistance between the conductors, until a desired resistor composed of the first and second resistor elements and having a predetermined resistance value is obtained.

  • Method for manufacturing a hybrid integrated circuit device
    Patent number: 4412377
    Abstract: A method for manufacturing a hybrid integrated circuit device comprising a step of forming an Al.sub.2 O.sub.3 layer on a metal substrate, a step of forming on the Al.sub.2 O.sub.3 layer a resist layer having a pattern opposite to that of a copper layer which will be formed on the Al.sub.2 O.sub.3 layer by a later step, a step of forming the copper layer on the Al.sub.2 O.sub.3 layer using the resist layer as a mask, a step of impregnating thermosetting material into both the Al.sub.2 O.sub.3 layer and the copper layer, and a step of providing at least one semiconductor element on the copper layer.
