Abstract:
PROBLEM TO BE SOLVED: To provide a memory device which can be easily manufactured and whose cell size can be shrunk. SOLUTION: The memory device, in which tunnel field-effect transistors (TFET) and embedded bit lines are used, includes a matrix containing a plurality of rows and columns of memory cells. Each memory cell includes at least one cell transistor (T01 to Tmn). The cell transistor includes a first doped region and a second doped region, wherein the one is a source region (98) and the other is a drain region (152). The memory device includes a plurality of word lines (WL0 to WLn). Each word line is connected to the memory cells belonging to the row and to the bit lines, while each bit line is connected to the memory cells belonging to the column. The doping type of the first doped region and that of the second doping region are different. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
An integrated circuit has a high voltage area, a logie area and a memory array for forming a system on a chip that includes linear, logic and memory devices. The memory has floating gate transistors disposed in a triple well structure with a raised drain bit line 13 substantially vertically aligned with a buried source bit line 14. The memory array separates the columns with deep trenches 46 that may also be formed into charge pump capacitors.
Abstract:
The invention relates to a memory circuit arrangement comprising a memory cell region (12) that contains a plurality of memory cell transistors (T00 to T21). The memory cell transistors (T00, T01) in a column are selected by means of a selection transistor (TD0). Said selection transistor (TD0) is a triple control-region transistor, whose control region extends as far as isolation trenches (G0, G1). The latter (G0, G1) also isolate the memory cell transistors (T00, T10) of different columns in the memory cell field (12). Said arrangement increases the level of integration.
Abstract:
The invention relates to a bitline structure with a surface bitline (DLx) and a buried bitline (SLx), whereby the buried bitline (SLx) is embodied in a trench with a trench insulation layer (6) and connected to doped regions (10) for contacting, by means of a surface connection layer (12) and a self-aligning junction layer (13) in an upper part region of the trench.
Abstract:
The invention inter alia relates to a method for producing a tunnel field-effect transistor (T1). The inventive method is characterized by producing differently doped connecting areas (28, 80) by means of self-aligned implantation methods.
Abstract:
The invention relates to a memory-circuit arrangement (10) wherein parts of the memory are located on two different substrates. A memory cell field (16), amongst other things, is located on one substrate. A control switch (38), amongst other things, is located on the other substrate. The production costs thereof are significantly reduced due to the clever division of memory.
Abstract:
A method for the production of bitlines (40) for a memory cell array, firstly comprises the step of preparation of a layer structure from a substrate (10) with a transistor trough (12) implanted in a surface thereof, a memory medium layer sequence (20), provided on the surface of the substrate (10) and a gate region layer (22), provided on the memory medium layer sequence (20). Bitline recesses are generated in the gate region layer (22), extending to the memory medium layer sequence (20). Insulating separation layers (36) are then generated on lateral surfaces of the bitline recesses, whereupon a source/drain implantation (38) is carried out after a complete or partial removal of the memory medium layer sequence (20) in the region of the bitline recesses. The substrate is completely exposed in the region of the bitline recesses should this not be the case before the implantation. A metallisation is then generated on the exposed substrate for production of metallic bitlines (40). Said metallisation is insulated from the gate region layer (22) by means of the insulating separation layers (36).
