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 semiconductor element including a substrate having a plurality of electrodes on a circumferential region thereof;
a first wiring coupled to one of the electrodes and disposed above the substrate;
at least one resin layer above the substrate and the first wiring;
a second wiring coupled to the first wiring and disposed above the at least one resin layer; and
a terminal provided on the second wiring,
wherein the terminal is provided nearer the circumferential region of the semiconductor element than a portion of the semiconductor element where the first wiring is coupled to the second wiring.
2. The semiconductor device according to claim 1 , wherein the semiconductor device is packaged with a chip size packaging method.
3. The semiconductor device according to claim 1 , wherein the terminal comprises a solder ball.
4. The semiconductor device according to claim 1 , wherein the first wiring and the second wiring are connected via a bore hole in the at least one resin layer.
5. The semiconductor device according to claim 1 , wherein the semiconductor device is cut from a silicon wafer by dicing.
6. The semiconductor device according to claim 5 , wherein the at least one resin layer is spaced apart from a portion of the silicon wafer to be cut during dicing.
7. The semiconductor device according to claim 1 , wherein the at least one resin layer is disposed on a region of the semiconductor element in which the electrodes are located.
8. A circuit substrate including the semiconductor device according to claim 1 .
9. An electronic apparatus including the semiconductor device according to claim 1 .
