Abstract
A semiconductor device has a substantially linear array of semiconductor blocks of one conductive type, each includes a diffusion region of the opposite conductive type and a electrode. The array is paralleled by an array of electrode pads, each connected to two semiconductor blocks, being connected to the diffusion region in one of the two semiconductor blocks and to the electrode in the other one of the two semiconductor blocks. The electrode pad can thus activate both semiconductor blocks, activating one semiconductor block when placed at one potential, and activating the other semiconductor block when placed at another potential. Efficient driving with a comparatively small number of electrode pads thus becomes possible.
