One embodiment of this invention pertains to a high throughput screening
technique to identify current leakage in matrix-structured electronic
devices. Because elements that are likely to develop a short have
relatively high leakage current at zero operation hours, by identifying
elements with the relatively high leakage current, the electronic devices
that are more likely to later develop a short can be differentiated. The
screening technique includes performing the following actions: selecting
one of multiple first lines; applying a first voltage to the selected
first line; applying a second voltage to the one or more of the first
lines that are not selected; floating the multiple second lines; and
measuring the voltages on the second lines, either sequentially one line
at a time or measuring all the lines at the same time.
