Semiconductor apparatus, which is constituted in minimum cell array area, while cell array property is maintained in which dummy cell is used

摘要

A semiconductor apparatus includes a cell and a dummy cell. The cell has a first conductivity type of diffusion layer formed in a second conductivity type of semiconductor region. The second conductivity type is opposite to the first conductivity type. The dummy cell has the second conductivity type of dummy diffusion layer formed in the semiconductor region. The dummy cell is adjacent to the cell.
