Abstract

See full text

A semiconductor device includes a semiconductor substrate. The semiconductor substrate includes multiple chip regions and a strip line for separating the chip regions. A test key is formed in the strip line and is used for a bit line contact (BLC) resistance test. The test key includes active regions and connecting structures. The active regions are formed in the semiconductor substrate. The connecting structures are located at ends of the active regions. The multiple active regions located on the same column are sequentially connected end to end by the connecting structures.
