Publication number: 20140015143Abstract: Electrical contacts may be formed by forming dielectric liners along sidewalls of a dielectric structure, forming sacrificial liners over and transverse to the dielectric liners along sidewalls of a sacrificial structure, selectively removing portions of the dielectric liners at intersections of the dielectric liners and sacrificial liners to form pores, and at least partially filling the pores with a conductive material. Nano-scale pores may be formed by similar methods. Bottom electrodes may be formed and electrical contacts may be structurally and electrically coupled to the bottom electrodes to form memory devices. Nano-scale electrical contacts may have a rectangular cross-section of a first width and a second width, each width less than about 20 nm. Memory devices may include bottom electrodes, electrical contacts having a cross-sectional area less than about 150 nm2 over and electrically coupled to the bottom electrodes, and a cell material over the electrical contacts.Type: ApplicationFiled: July 12, 2012Publication date: January 16, 2014Applicant: MICRON TECHNOLOGY, INC.Inventors: Jun Liu, Kunal R.

Patent number: 8629542Abstract: A Three-Dimensional Structure (3DS) Memory allows for physical separation of the memory circuits and the control logic circuit onto different layers such that each layer may be separately optimized. One control logic circuit suffices for several memory circuits, reducing cost. Fabrication of 3DS memory involves thinning of the memory circuit to less than 50 ?m in thickness and bonding the circuit to a circuit stack while still in wafer substrate form. Fine-grain high density inter-layer vertical bus connections are used. The 3DS memory manufacturing method enables several performance and physical size efficiencies, and is implemented with established semiconductor processing techniques.Type: GrantFiled: March 17, 2009Date of Patent: January 14, 2014Inventor: Glenn J.
