Abstract
A semiconductor device with trench isolation structure is disclosed. The invention uses a trench isolation structure that can be formed by using conventional methods to prevent problems such as drain induced barrier lowering (DIBL), punch-through leakage and spiking leakage. Thus these poor electrical properties of the conventional semiconductor device with a shallow junction depth resulting from the shrink of design rules can be solved.
