Abstract
A substrate with reinforced contact pad structure includes a metal wiring layer and a solder mask formed over its surface. The metal wiring layer includes at least a NSMD (Non-Solder Mask Defined) type contact pad, a trace and an extension. The extension connects the contact pad and the trace, and has an upper surface which is covered by the solder mask so as to enhance the connecting strength between the trace and the contact pad and to improve the position stability of the NSMD type contact pad on the substrate. In an embodiment, the contact pad is circular for bonding a bump or a solder ball. The first extension is fan-shaped. The extension also has a sidewall exposed out of the solder mask.
