Abstract
A method can be used to manufacture a charge storage cell with a first trench and a second trench in a substrate material. The first trench is filled with a doped material. The second trench is filled with a second trench material. The method includes causing the dopant to diffuse from the first trench to thereby provide a doped region adjacent to the first trench. The material from the first and second trenches is removed and at least one of the trenches is filled with a capacitive deep trench isolation material to provide capacitive deep trench isolation.
