Patent number: 6734063Abstract: Memory cell transistors with back-channel isolation are produced without using an SOI substrate. With the word line stack acting as a mask, the semiconductor material is etched on both sides of the world line, first anisotropically and then isotropically to widen the etch hole and form an undercut beneath the gate electrode and at a distance from the ONO storage layer forming the gate dielectric. The undercut is filled, whereby a buried oxide layer of at least 20 nm maximum thickness is formed underneath the channel region. The latter is p-doped at a density of at least 1017 cm−3.Type: GrantFiled: July 22, 2002Date of Patent: May 11, 2004Assignees: Infineon Technologies AG, Ingentix GmbH & Co.

Patent number: 6472696Abstract: The memory cell configuration has a large number of memory cells provided in a semiconductor substrate and having bit-line trenches which extend in parallel in the longitudinal direction in the main face of the semiconductor substrate, at the bottoms of which in each case a first conductive region is provided, at the peaks of which in each case a second conductive region of the same conduction type as the first conductive region is provided, and in the walls of which in each case an intermediately located channel region is 0 provided; and having word lines which extend in the transverse direction along the main face of the semiconductor substrate, through specific bit-line trenches, to activate transistors provided there. An additional dopant is introduced into the trench walls of the bit-line trenches which are located between the word lines, in order to increase the corresponding transistor turn-on voltage there to suppress leakage currents.Type: GrantFiled: August 25, 2000Date of Patent: October 29, 2002Assignee: Infineon Technologies AGInventors: Ulrich Zimmermann, Thomas Böhm, Manfred Hain, Armin Kohlhase, Yoichi Otani, Andreas Rusch, Alexander Trüby

Patent number: 6281557Abstract: A read-only memory cell array has vertical MOS transistors formed on trench walls, and is programmed with a programming mask which covers only the areas at which a transistor is not to be produced. As a result, the word lines can be formed with minimum grid spacing and the risk of short-circuiting between adjacent word lines is eliminated by buried ploy stringers.Type: GrantFiled: July 30, 1998Date of Patent: August 28, 2001Assignee: Infineon Technologies AGInventors: Alexander Trueby, Ulrich Zimmermann, Armin Kohlhase

Patent number: 6258658Abstract: The memory cell configuration has a multiplicity of preferably ferroelectric memory cells in a semiconductor substrate. Mutually parallel bit line trenches run in the longitudinal direction in the main surface of the semiconductor substrate. Bit lines are disposed in the bottoms of the trenches. Source/drain regions are formed in the crowns of the trenches. Channel regions are provided in the walls of the trenches. The channel region on a wall in each case is configured such that a drivable selection transistor of the relevant memory cell is formed there, while the channel region on the other wall is configured such that the transistor located there is closed. Insulated word lines for driving the selection transistors run in the transverse direction along the main surface of the semiconductor substrate through the bit line trenches.Type: GrantFiled: February 12, 1999Date of Patent: July 10, 2001Assignee: Infineon Technologies AGInventors: Thomas Böhm, Volker Weinrich, Manfred Hain, Armin Kohlhase, Yoichi Otani, Andreas Rusch, Till Schlösser
