Abstract:
1. An apparatus for forming bumps on a workpiece having a semiconductor wafer, comprising: a bump bonding device for forming bumps on members arranged in a grid pattern on a workpiece, the members including ICs; a recognition device, including an image pickup camera movable in column and row directions above the workpiece to image detection marks on the workpiece, for detecting a position and an inclination of the members based upon image pickup information of said image pickup camera; a control device configured to: a wafer turning member onto which the semiconductor wafer is to be loaded, said wafer turning member being rotatable in a circumferential direction of the semiconductor wafer when loaded on said wafer turning member; and a turning device for turning said wafer turning member in the circumferential direction via control of said control device; wherein the control device is also configured to:
