Abstract
There is herein disclosed a semiconductor device comprising an internal cell area,on which various logic circuits are formed, an I/O cell area,via which a signal is received/transmitted between a pad for connection to the outside and said internal cell area,an external pad area,formed outside the I/O cell area,and an internal pad area,formed between the internal cell area,and the I/O cell area,Since the internal pad area,is disposed not only outside the I/O cell area,but also between the I/O cell area,and the internal cell area,the number of pads for the connection to the outside can be increased more than that of a conventional art, and a large number of pins of a chip can be handled. Moreover, since a pad interval does not have to be narrowed, reliability is improved, and manufacture yield is raised.
