Semiconductor device and its writing method
View Patent ↗A semiconductor device mounted on a mother board has a circuit board to be positioned on the mother board and a semiconductor chip positioned on the circuit board. The circuit board has a connection pad, a relay pad spaced away from the connection pad, and a wire connecting between the connection pad and the relay pad on a surface of the circuit board supporting the semiconductor chip. Also, the semiconductor chip has a connection pad corresponding to the connection pad formed on the circuit board. Further, the connection pad on the circuit board and the connection pad on the semiconductor chip are electrically connected to each other through a bonding wire.
1. A semiconductor device, comprising:
a first semiconductor chip having a first pad;
a second semiconductor chip having a second pad,
a third pad and a connecting wire electrically connecting the second pad with the third pad;
a circuit board having a fourth pad;
a first bonding wire connecting the first pad and the second pad;
a second bonding wire connecting the third pad and the fourth pad,
wherein the connecting wire is interlaid under the second pad and the third pad in the second semiconductor chip, spaced apart from a top surface of the second semiconductor chip,
the second pad is formed on the top surface of the second semiconductor chip, beside one edge, and
the third pad is formed on the top surface of the second semiconductor chip, beside another edge.
