Title: Probing method for semiconductor
Inventor: KATO KENICHI
IPC: H01L21/66
Filed: 1985-12-16
Abstract: PURPOSE:To identify which marking mechanism malfunctions on two simultaneous measurements by completing the test of pellets in one wafer, conducting specific decision operation and mechanically performing marking. CONSTITUTION:The test of pellets in one wafer is completed, and at least one or more of nondefectives in a first chip and a second chip are checked. When there are one or more of nondefectives as the result of the check, the first chip is forwarded to a position as nondefectives, and the second chip is fed to a position as defectives and retested. The coincidence of the result of the retest and data on the test of the pellet is checked, the first chip as the nondefective in the process is marked intentionally, and a change into a defective of the first chip is checked when the chip is checked again. Consequently, the operation of a mechanism in which the defective chip is marked is made sure. Accordingly, the malfunction of any marking mechanism can be confirmed even on two simultaneous measurements.

Title: Semiconductor device and its manufacture
Inventor: YAMAZAKI SATOSHI
IPC: H01L29/78
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To obtain desired circuit characteristics, without shorting a source- drain-forming silicide layer with a semiconductor substrate by forming the silicide layer apart from a field oxide film. SOLUTION: Since an oxide film 7 should be patterned not to expose the ends of a field oxide film 2, the etching ends of the oxide film 7 have extensions 9 located on a diffusion layer 6 at inner Tr regions. A Ti film of about 350nm thick is formed on the entire surface by the sputtering and heated at 700-900 deg.C in an inert gas atmosphere to from a Ti silicide layer 8 on the diffusion layer 6 at the inner Tr regions. Since the field oxide film 2 is covered with the film 7, the silicide layer on the diffusion layer 6 is distant from the ends of the oxide film 2 and hence never contacts an Si substrate 1. This improves the electrostatic breakdown resistance.
