Patent number: 7223651Abstract: A memory cell includes a selection transistor and a trench capacitor. The trench capacitor is filled with a conductive trench filling on which an insulating covering layer is arranged. The insulating covering layer is laterally overgrown, proceeding from the substrate with a selectively grown epitaxial layer. The selection transistor is formed in the selectively grown epitaxial layer, comprises a source region connected to the trench capacitor and a drain region connected to a bit line. The junction depth of the source region is chosen so that the source region reaches as far as the insulating covering layer. Optionally, the thickness of the epitaxial layer can be reduced to a thickness by oxidation and a subsequent etching. Afterwards, a contact trench is etched through the source region down to the conductive trench filling, which trench is filled with a conductive contact and electrically connects the conductive trench filling to the source region.Type: GrantFiled: June 5, 2002Date of Patent: May 29, 2007Assignee: Infineon Technologies, AGInventors: Frank Richter, Dietmar Temmler, Andreas Wich-Glasen

Patent number: 7129155Abstract: Process for producing a plurality of gate stacks approximately the same height and equidistant on a semiconductor substrate. The process includes providing a gate dielectric on the semiconductor substrate and applying and patterning at least a first layer and a second layer, above the first layer, to the gate dielectric to produce the gate stacks. An oblique implantation of an oxidation-inhibiting implantation species is carried out into two opposite, uncovered side faces of the second of the gate stacks, with respectively adjacent gate stacks serving to shadow the uncovered side faces of the first layer of the gate stacks. Oxidation to simultaneously form a first oxide layer on uncovered side faces of the first layer of the gate stacks and a second oxide layer on uncovered side faces of the second layer of the gate stacks is carried out, the thickness of the first oxide layer being greater than the thickness of the second oxide layer.Type: GrantFiled: August 12, 2004Date of Patent: October 31, 2006Assignee: Infineon Technologies AGInventors: Martin Popp, Andreas Wich-Glasen

Patent number: 7125778Abstract: A description is given of a method for a selective masking of a structure with a small structure surface with respect to a structure with a larger structure surface. To that end, the structures are filled with a covering layer. The covering layer is formed with a larger thickness above the first structure, which has the larger structure surface, than above the second structure. Afterward, the covering layer is removed by a homogeneous removal method, so that first the structure surface of the second structure is uncovered. A simple self-aligning method for fabricating a mask for uncovering the second structure is thus provided.Type: GrantFiled: August 27, 2002Date of Patent: October 24, 2006Assignee: Infineon Technologies AGInventors: Dirk Efferenn, Ulrike Grüning Von Schwerin, Hans-Peter Moll, Jörg Radecker, Andreas Wich-Glasen

Publication number: 20060231918Abstract: A transistor is provided which advantageously utilizes a part of the area which, in conventional transistors, is provided for the isolation between the transistors. In this case, the channel width can be enlarged in a self-aligned manner without the risk of short circuits. The field-effect transistor according to the invention has the advantage that it is possible to ensure a significant increase in the effective channel width for the forward current ION compared with previously used, conventional transistor structures, without having to accept a reduction of the integration density that can be attained. Thus, by way of example, the forward current ION can be increased by up to 50%, without having to alter the arrangement of the active regions or of the trench isolation.Type: ApplicationFiled: June 19, 2002Publication date: October 19, 2006Inventors: Martin Popp, Frank Richter, Dietmar Temmler, Andreas Wich-Glasen

Patent number: 7119384Abstract: The invention relates to a field effect transistor in which the planar channel region on the upper surface of the elevation is extended in width by means of additional vertical channel regions on the lateral surfaces of the elevation. Said additional vertical channel regions connect directly to the planar channel region (vertical extended channel regions). Said field effect transistor has the advantage that a significant increase in the effective channel width for the current flow ION can be guaranteed relative to conventional transistor structures used up until the present, without having to accept a reduction in the achievable integration density. Said field effect transistor furthermore has a low reverse current IOFF. The above advantages are achieved without the thickness of the gate insulators up to the region of the charge transfer tunnels having to be reduced or a reduced stability.Type: GrantFiled: June 25, 2002Date of Patent: October 10, 2006Assignee: Infineon Technologies AGInventors: Martin Popp, Frank Richter, Dietmar Temmler, Andreas Wich-Glasen
