Patent ID: 7872337

Claim:
A semiconductor device, comprising: a case; an insulating substrate provided within said case; a plurality of semiconductor chips mounted on said insulating substrate, each of said semiconductor chips having a first chip electrode for receiving a control signal; and a flexible board supported by said case, including a body portion and a plurality of integrally formed lead portions that are arrayed in a first direction and that extend from the body portion in the same plane in a second direction that is substantially perpendicular to the first direction; said body portion and said plurality of lead portions of said flexible board each comprising a flexible insulating film and conductive patterns formed thereon such that at least one of the conductive patterns is formed on each respective one of said plurality of lead portions, the plurality of lead portions being spaced from each other in the first direction such that each lead portion is separated from an adjacent lead portion in the first direction by an open space that is free of the flexible insulating film; wherein each of the first chip electrodes is electrically connected with one of the conductive patterns on the flexible insulating film in the respective one of the lead portions.
