Patent ID: 8540001

Claim:
A die bonder, comprising: a bonding head that adsorbs a die from a wafer and bonds it to a substrate; a first adjustment mechanism that positions the bonding head in order to position a position of the die at predetermined accuracy; a second adjustment mechanism that is provided to the bonding head, and adjusts the position of the die at higher accuracy than the first adjustment mechanism; a positioning controller that controls the first adjustment mechanism and the second adjustment mechanism; a reference mark provided to a substrate or in the vicinity of the substrate; a first imaging means that images the reference mark and a recognition pattern provided to a bonding position of the substrate; a second imaging means that images the reference mark and the die brought close to the bonding position; and a misregistration detector provided with a correcting means that corrects a position of the die brought close to the bonding position based upon imaged data acquired by the first and second imaging means.
