Abstract

Salient electrodes on a semiconductor chip and leads on a film substrate are to be connected together with a high accuracy. A change in lead pitch which occurs at the time of connecting salient electrodes on a semiconductor chip and inner leads on a film substrate with each other is taken into account and a correction is made beforehand to the pitch of the inner leads. Likewise, a change in lead pitch which occurs at the time of connecting electrodes on a liquid crystal substrate and outer leads on the film substrate with each other is taken into account and a correction is made beforehand to the pitch of the outer leads.
