Abstract:
A semiconductor device comprising:a substrate made of an electro-insulating material and having first and second surfaces, the substrate having connector terminals formed on the first surface thereof and external connecting terminals formed on the second surface thereof, wherein a plan view contour of the substrate is selected from the group consisting essentially of a substantially square shape and a substantially rectangular shape, having in a plan view two pairs of parallel sides and two diagonal lines;a semiconductor chip having electrodes, wherein the semiconductor chip is mounted on the first surface of the substrate, so that the electrodes of the semiconductor chip are flip-chip bonded with the connector terminals of the substrate, wherein a plan view contour of the semiconductor chip is selected from the group consisting essentially of a substantially square shape and a substantially rectangular shape, having in a plan view two pairs of parallel sides and two diagonal lines;the semiconductor chip being arranged with respect to the substrate in such a manner that a center of the semiconductor chip coincides with a center of the substrate in plan view, wherein in plan view each diagonal line of the semiconductor chip is not parallel to a diagonal line of the substrate and each side of the semiconductor chip is not parallel to a side of the substrate; anda cured adhesive that fills a gap between the substrate and the semiconductor chip, wherein warpage of the substrate is less than warpage in a semiconductor device that has each side of the semiconductor chip parallel to a side of the substrate.
