Abstract: <P>PROBLEM TO BE SOLVED: To improve the recognition accuracy of an electrode pad at the time of bonding and probing.  <P>SOLUTION: Around the opening of a pad protective film 6 on the electrode pad (1), a different level 7 whose cross section is tapered or arcuate is formed. Thus, at the time of recognizing the electrode pad (1) at the time of bonding and probing, since the reflected amount of light becomes largely different between the different level 7 of the pad protective film 6 and the other part at the time of irradiating a pad with the light from above, the different level 7 is easily recognized and the recognition accuracy is substantially improved. The electrode pad (1) is recognized by recognizing the different level 7, and the recognition accuracy of the electrode pad is remarkably improved. Thus, the electrode pad is easily recognized even at the time of pad pitch reduction and pad opening side reduction by a fine process.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
