Problems solved by technology

[0006] However, when a chip is flip-chip mounted on a printed circuit board via bumps, an adhesive interface (contact resistance) is generated between the bonding material and the pad, resulting in a large heat transfer loss.

Abstract

The present invention provides a semiconductor device and a manufacturing method thereof. The semiconductor device can be installed with a flip-chip with a little heat loss between a chip and a printing substrate. The semiconductor device comprises: a printing substrate and a chip. The main surface of the printing substrate is configured with a substrate electrode pad with a plurality of spikes composed of graphite on the surface. The main surface of the chip opposite to the substrate electrode pad is provided with a chip electrode pad with conductive resin film contacted with the front ends of the spikes.

Description

technical field [0001] The present invention relates to a semiconductor device having a chip flip-chip mounted on a printed board and a method of manufacturing the same. Background technique [0002] As one method of mounting a chip on which a semiconductor element is formed on a printed board, flip chip mounting is used. For example, by flip-chip mounting a light emitting diode (LED), the number of electrodes arranged on the light emitting surface of the LED can be reduced. Therefore, the luminous efficiency of LED improves. [0003] In order to perform flip-chip mounting of LEDs, a method of forming bumps on electrodes arranged on LEDs, etc. have been studied (for example, refer to Patent Document 1). The LED and the printed board are electrically connected by electrically connecting bumps formed on the LED to pads arranged on the printed board. [0004] As for the bump forming method, there are ball bonding method, printing method, and the like. For example, solder pa...
