Abstract
PURPOSE:To facilitate a pattern design and to make the size of a mask pattern small, by realizing pull up or pull-down by only addition of a pattern of contact on a cell. CONSTITUTION:Input signal lines 1 and 2 are made to cross with a power source line 3 with an insulation layer in between, and input signal lines 1' and 2' are disposed to cross with a ground line 4. When the input signal lines 1, 1' and 2, 2' are made to be on pull-down and pull-up states respectively, a desired mask pattern is realized by forming patterns of contact holes 5 and contact pads 6 additionally on respective regions where the input signal lines 1' cross with the ground line 4 and where the input signal lines 2 cross with the power source line 3. Accordingly a pattern design is facilitated and a size of a mask pattern is made small.
