Publication number: 20110201161Abstract: A mask layer formed over a semiconductor substrate is lithographically patterned to form an opening therein. Ions are implanted at an angle that is normal to the surface of the semiconductor substrate through the opening and into an upper portion of the semiconductor substrate. Straggle of the implanted ions form a doped region that laterally extends beyond a horizontal cross-sectional area of the opening. A deep trench is formed by performing an anisotropic etch of a semiconductor material underneath the opening to a depth above a deep end of an implanted region. Ion implantation steps and anisotropic etch steps are alternately employed to extend the depth of the doped region and the depth of the deep trench, thereby forming a doped region around a deep trench that has narrow lateral dimensions. The doped region can be employed as a buried plate for a deep trench capacitor.Type: ApplicationFiled: February 15, 2010Publication date: August 18, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Joseph Ervin, Geng Wang

Patent number: 7791124Abstract: A bottle shaped trench for an SOI capacitor is formed by a simple processing sequence. A non-conformal dielectric layer with an optional conformal dielectric diffusion barrier layer underneath is formed on sidewalls of a deep trench. Employing an isotropic etch, the non-conformal dielectric layer is removed from a bottom portion of the deep trench, leaving a dielectric spacer covering sidewalls of the buried insulator layer and the top semiconductor layer. The bottom portion of the deep trench is expanded to form a bottle shaped trench, and a buried plated is formed underneath the buried insulator layer. The dielectric spacer may be recessed during formation of a buried strap to form a graded thickness dielectric collar around the upper portion of an inner electrode. Alternately, the dielectric spacer may be removed prior to formation of a buried strap.Type: GrantFiled: May 21, 2008Date of Patent: September 7, 2010Assignee: International Business Machines CorporationInventors: Kangguo Cheng, Herbert L.
