Abstract: A memory cell and a process for making it are disclosed. The ROM code is not implanted in the floating gate for cells selected to be "off". This memory cell has a much lower threshold voltage than conventional cells and the implantation induced crystal damage is avoided.

Abstract: A security element for the authentication of a substrate has a pattern comprising optical diffraction elements which are embossed in a carrier material of plastic material and unembossed neutral areas. On the embossing side of the carrier material a reflecting layer covers only surfaces with relief structures of the diffraction elements while the neutral areas which lie therebetween are free of the reflecting layer and are therefore non-reflecting. If the security element is stuck in the form of a stamp onto the substrate and the carrier metal is transparent, image portions, which are covered by the stamp, of a feature on the substrate can be discerned through the neutral areas.

Abstract: A buried bit line memory cell and fabrication process are disclosed. A plurality of exposed windows of a semiconductor material are formed which are separated by mesas. An oxide region is then formed in the vicinity of each exposed surface window. The formed oxide regions encroach under the mesas and therefore cover and area which is greater than the original windows. The mesas are then removed to expose a second set of narrow windows of the surface of the semiconductor material separated by the oxide regions. Impurities are then implanted or diffused into the substrate through the second set of narrow surface windows to form doped regions. The doped regions are delineated by the edges of the oxide regions and are therefore narrower than the width of the mesas. At least some of the doped regions form the buried bit lines of the memory cells.

Abstract: A ROM array comprises orthogal sets of buried bit lines and polysilicon wordlines. The buried bit lines comprise trenches with insulating material on the side walls, the trenches then being filled with polysilicon. This reduces bit line sheet resistance and increases the punch-through voltage between adjacent bit lines.

Abstract: In accordance with the invention, the emitter region of a BJT is formed prior to the formation of the base contact regions so that the base contact regions are not enlarged during a thermal cycle used to form the emitter and the base contact regions remain small. Preferably, the base contact regions are formed by ion implantation after the emitter is formed. In addition, the base interconnect links may be metal (or polycide) rather than polysilicon so that the base interconnect resistance is reduced.This results in the following advantages:(1) reduced emitter-base junction leakage(2) reduced collector-base junction capacitance.(3) reduced base interconnection series resistance.

Abstract: A pixel block transfer system has a shifter, at least two registers, an extractor and a mask. Parameter evaluation logic is used to generate most of the parameters needed in the pixel block transfer. The start address of the source block, the start address of the destination block, the number of pixels in the source block and the number of rows in the source block are input to the parameter evaluation logic. The parameter evaluation logic then determines the left shift number, the number of read data, the number of write data, the two write flag, the two read flag, the left mask number and the right mask number. The start addresses, the flags and the read and write numbers are sent to a state machine. These are used to control the pixel block transfer. The left shift number is sent to the shifter and the extractor. It signifies the number of pixels to be shifted left. The left and right mask numbers are sent to the mask to control which pixels are masked and, therefore, not modifiable.
