Abstract: In first step specified insulation (5) is deposited on semiconductor substrate (1) and onto surface is applied memory layer stack of first boundary layer (2), memory layer (3) and second boundary layer (4). In second step, first conductivity doped troughs (6) are formed by mask technique and application of doping material into semiconductor substrate. In third step, opposite conductivity doped troughs (7) are formed by doping semiconductor substrate. By using the same mask, in second step at least second boundary layer in region (10) for first conductivity troughs is removed. By using the same mask, in third layer at least second boundary layer in region (11) for second conductivity troughs is removed.

Abstract: The method involves applying two spacer layers conformally on a structure layer, and etching the spacer layers anisotropically, so that a spacer (5) is formed on side walls of lamellar portions of the structure layer and a spacer (7) is formed on side walls of the spacer (5).. The structure layer is removed, so that the spacer stays with the respective side walls, and a complementary layer (8) is applied to fill free spaces. An even surface is formed on an upper side of the spacers and the complementary layer, and the two spacers or the complementary layer are removed.

Abstract: Production of planar NROM (nitrided read only memory) cells having gate electrodes, a gate oxide and bit lines comprises forming an oxide for insulating the bit lines and an oxide for forming the gate oxide whilst thermally oxidizing a semiconductor material. Nitrogen is implanted in the region of the bit lines before the oxide of the bit lines is formed in the semiconductor material so that an oxidation rate is adjusted. Preferred Features: Additional low voltage components are produced. Implantation of nitrogen in the region of the bit lines is carried out so that the oxidation rate is lower than the oxidation rate in the region of the components.

Abstract: The device has electronic chips and a memory device with a stored classification map with position and classification information for at least one part of the chip. The position information gives the position of each chip on the wafer and the classification information gives a classification of each chip in accordance with a given criterion. An Independent claim is also included for a wafer manufacturing method.

Abstract: The bit lines are produced by an implantation of a dopant by means of a sacrificial hard mask layer, which is later replaced with the gate electrodes formed of polysilicon in the memory cell array. Striplike areas of the memory cell array, which run transversely to the bit lines, are reserved by a blocking layer to be occupied by the bit line contacts. In these areas, the hard mask is used to form contact holes, which are self-aligned with the implanted buried bit lines. Between the blocked areas, the word lines are arranged normally to the bit lines.
