摘要:
A memory cell includes a transistor and a capacitor that is a doped polysilicon filled trench. A doped polycrystalline strap provides a low resistance connection between a source region of the transistor and the polysilicon fill and is shaped to overlie both a top surface and a side surface of the source region of the transistor.
