Abstract

A flip chip type semiconductor device for reducing signal skew includes: a chip with bonding pads, and a plurality of bumping pads on the chip. Between each bonding pad and corresponding bumping pads is connected with a metal redistribution trace covered by a passivation layer. Each metal trace has an equal trace length for reducing signal skew.
