摘要： A method for fabricating the semiconductor device comprises providing a semiconductor substrate having a device region and a testkey region. A first trench is formed in the device region and a second trench is formed in the testkey region. A conductive layer with a first etching selectivity is formed in the first and second trenches. A first implantation process is performed in a first direction to form a first doped region with a first impurity and an undoped region in the conductive layer simultaneously and respectively in the device region and in the testkey region. A second implantation process is performed in the second trench to form a second doped region with a second impurity in the conductive layer, wherein the conductive layer in the second trench has a second etching selectivity higher than the first etching selectivity.
