Title:
配線ショート箇所の検査方法及び検査装置
Document Type and Number:
Japanese Patent JP4290316
Kind Code:
B2
Abstract:
In a method for detecting a line-short between conductive layers, a potential (or temperature) distribution of the conductive layers is detected while applying a DC voltage thereto. The method is particularly applicable to interdigitated conductive layers. A potential distribution across a wide range perpendicular to the conductors is detected to determine a first location of the line short. Potential distributions between conductors at points parallel to the conductors near the first location are then examined to determine a second location where the potential between the conductors is minimal. Potential distribution at points along a conductor are then examined to determine a location where the potential is sharply changed.
