Abstract: A method of detecting low-probability defects in large transistor arrays (such as large arrays of SRAM cells), where the defects manifesting themselves as asymmetrical leakage in a transistor (such as a pulldown nFET in an SRAM cell). These defects are detected by creating one or more test arrays, identical in all regards to the large transistor arrays up until the contact and metallization layers. The test array(s) is (are) disposed side-by-side with the “normal” array(s) on the same reticle so that process variations that affect the normal array will also affect the test array. The contact and metallization layers for the test array are adapted to connect groups (sub-blocks) of transistors together in parallel for leakage testing. The group size is chosen to ensure that the leakage current associated with a single defective transistor is significantly greater than the aggregate leakage current associated with all of non-defective transistors in the group.
