SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME |
摘要 |
Provided is a method for fabricating a semiconductor device, including the following steps. A substrate having a plurality of pillars is provided, wherein a plurality of trenches are formed around each pillar. A doped region is formed in the substrate and below each pillar. The doped region below each trench is removed to form an opening such that the doped regions below the adjacent pillars are separated from each other. A shielding layer is formed in each opening. |

1. A method for fabricating a semiconductor device, comprising:
providing a substrate having a plurality of pillars, wherein a plurality of trenches are formed around each pillar; forming a doped region in the substrate below each pillar; removing the doped region below each trench to form an opening such that the doped regions below the adjacent pillars are separated from each other; and forming a shielding layer inside each of the opening. |
