Abstract:
1. A method of forming a semiconductor structure comprising: providing a semiconductor-on-insulator substrate that comprises at least one via contact extending through an SOI layer and a buried insulating layer of said semiconductor-on-insulator substrate and at least one storage capacitor including a node conductor; providing an oxide cap atop a portion of said node conductor, while leaving another portion of said node conductor exposed; recessing the exposed portion of the node conductor and forming a conductive strap in said recess; removing the oxide cap and forming a top trench oxide atop a portion of said node conductor and said conductive strap; and forming a read wordline atop the top trench oxide and forming a write wordline atop an exposed surface of said SOI layer, wherein said read wordline is an element of a transistor which includes side-gating and a top gate.
