Semiconductor device, method of manufacturing thereof, circuit board and electronic apparatus
View Patent ↗A semiconductor device is provided comprising: a semiconductor element including a plurality of electrodes; first wirings coupled to the electrodes and directed toward a center of the semiconductor element from a portion coupled to the electrodes; second wirings coupled between the first wirings and external terminals, the second wirings being directed to an outer area of the semiconductor element relative to the center; and at least one resin layer formed between the first wirings and the second wirings.
1. A semiconductor device comprising:
a first wiring being connected to an electrode;
a first resin layer on the first wiring having a through hole;
a second wiring on the first resin layer being connected to the first wiring via the through hole;
a terminal being provided on the second wiring;
a second resin layer on the first resin layer and the second wiring having a lower elasticity than the first resin layer; and
a third resin layer on the second resin layer having a lower elasticity than the second resin layer.
2. The semiconductor device according to claim 1 , wherein the terminal is provided nearer a circumferential region of the semiconductor device than the through hole.
3. The semiconductor device according to claim 1 , wherein the terminal is protruded from the second resin layer and the third resin layer.
4. The semiconductor device according to claim 1 , wherein the terminal comprises a solder ball.
5. A circuit substrate including the semiconductor device according to claim 1 .
6. An electronic apparatus including the semiconductor device according to claim 1 .
