Semiconductor device and a method of manufacturing the same

A semiconductor device comprising:

• a semiconductor element formed on a substrate;
• a wiring layer formed over said semiconductor element and having wiring connected to said semiconductor element;
• and
• a pad formed over said wiring layer,
• wherein in said wiring layer, an area occupation rate of wirings arranged in an area of a planar region of said pad and formed under said pad is at least 50% of said area, and
• wherein there are a plurality of said semiconductor element that constitute circuits for driving a liquid crystal display.

A semiconductor device comprising:

• a wiring layer formed over a semiconductor element on a substrate;
• and
• a first pad and a second pad formed over said wiring layer,
• wherein in said wiring layer, area occupation rates of wirings arranged in areas of respective planar regions of said first and second pads, and formed under said first and second pads, are at least 50% of the respective areas.
