Publication number: 20060148178Abstract: The present invention relates to a method for producing a vertical transistor, and to a vertical transistor. A sacrificial gate oxide and a sacrificial gate electrode are used during the production of the vertical transistor to makes it possible to considerably reduce or entirely avoid negative effects that normally result from the production of insulation structures between the vertical transistors. In particular, broadening of the gate oxide at the edge of the gate electrode can be prevented, and the edge of the gate electrode can be influenced deliberately. This allows vertical transistors to be produced having a current/voltage characteristic that can be adjusted specifically. In particular, vertical transistors can be produced having a pronounced corner effect.Type: ApplicationFiled: March 3, 2006Publication date: July 6, 2006Inventors: Dietrich Bonart, Gerhard Enders, Peter Voigt

Patent number: 6838335Abstract: A semiconductor memory is fabricated with a vertical transistor situated in an upper section of a trench above a trench capacitor. First, an auxiliary insulation layer is applied to the conductive material of an inner electrode or to a connecting material of the trench capacitor. The connecting material is situated on the inner electrode, so that, during an epitaxial deposition, semiconductor material grows only on the uncovered sidewalls in the upper section of the trench. A nitride layer, is deposited conformally and the residual cavity between the inner electrode and the epitaxial semiconductor layer is filled with a doped further conductive material. The nitride layer isolates the epitaxial semiconductor layer from the further conductive material, so that no crystal lattice defects can propagate from there into the epitaxial semiconductor layer. Dopants are outdiffused from the further conductive material into the epitaxial semiconductor layer to form a doping region.Type: GrantFiled: July 25, 2003Date of Patent: January 4, 2005Assignee: Infineon Technologies AGInventors: Dietrich Bonart, Gerhard Enders, Peter Voigt
