Abstract
A transistor structure includes a semiconductor substrate, a gate region, a first trench, a first isolation region and a first conductive region. The semiconductor substrate is with an original semiconductor surface. The gate region is over the semiconductor surface. The first trench is formed below the original semiconductor surface. The first isolation region is in the first trench. The first conductive region is formed with a first doping region and a second doping region; wherein the first doping region is within the semiconductor substrate and the second doping region is formed outside from the semiconductor substrate.
