<p>PURPOSE:To standardize a semiconductor device and to eliminate the error in the wiring pattern of the device by forming in advance the wiring pattern secured on a substrate in the midway of the wire which connects an input/output level converter to an internal logic circuit in the peripheral pattern of complicated shape. CONSTITUTION:Input converters 41, 42 and output transistor 51 are respectively formed at a ratio of 1:1/2 at terminal pads 21, 22, and virtual external terminal groups 71, 72, 73 disposed at the end of a wiring channel and virtual external terminal groups 74, 75, 76 are respectively corresponded to pads 21 and 22. Wiring pattern pads 21, 22 which connect the virtual external terminal groups corresponding to the respective pads are prepared in advance with stationary wires 81, 82 corresponding thereto. Patterns 91, 92 are inhibited in wiring due to complicated pattern shape. In this manner, a program due to the design automation can be facilitated, and the error in the pattern can be eliminated, thereby standardizing and simplifying the wiring shape.</p> |
