Abstract:
1. A method of manufacturing a hybrid integrated circuit device comprising: preparing a lead frame which is constituted by units each having a plurality of leads; and fixing a circuit substrate on each unit of the lead frame by fixing pads formed on a surface of the circuit substrate to the leads, providing the circuit substrate with a first side edge and a second side edge opposite to said first side edge, and also with a third side edge and a fourth side edge opposite to said third side edge, with said first and second side edges extending in a first direction and said third and fourth side edges extending in a second direction that is substantially perpendicular to said first direction, further including disposing a plurality of pads in the vicinities of and along the first side edge from the vicinity of a first end of said first side edge to the vicinity of a second end of said first side edge, wherein a space between a first pad of said plurality of pads which is formed at said first end of said first side edge of the circuit substrate and a second pad which is adjacent to the first pad is set narrower than a space between other pads of said plurality of pads, wherein a space between a third pad of said plurality of pads which is formed at said second end of said first side edge of the circuit substrate and a fourth pad which is adjacent to the third pad is set narrower than a space between said other pads, further including transfer molding said circuit substrates on said lead frame to perform sealing with resin, wherein the fixing of the leads and the pads to each other is performed with only brazing material, and further including said circuit substrate being surrounded around all of said first, second, third and fourth side edges by a support portion of the lead frame.
