Disclosed is a method for analyzing a defect of a semiconductor device,
and more particularly a method for electrically analyzing a defect of a
transistor formed in a cell having a latch structure, such as SRAM or a
sense amplifier of DRAM. The defect analyzing method according to the
present invention comprises the steps of forming a test SRAM cell array
in a scribe lane region of a wafer which is formed with a plurality of
SRAM chips, forming a pad portion for testing the SRAM cell array on the
scribe lane region, and applying a predetermined test voltage to the SRAM
cell array through the pad portion. The respective array cells
constituting the SRAM cell array are provide with two word lines, and
individual test voltages can be applied through the pad portion to the
two word lines, respectively.
