| 摘要 |
The semiconductor device according to the present invention has a planar semiconductor chip having projecting connection terminals provided on one surface thereof. A shelf is provided where a peripheral edge of a surface of the semiconductor chip opposite one surface thereof onto which connection terminals are provided is removed. This makes it possible to secure a larger volume of the fillet portion of the underfill, thereby helping improve the function of preventing the rising up of the excess underfill by providing a shelf in the semiconductor chip.
