Abstract: Memory devices having improved TPD characteristics and methods of making the memory devices are provided. The memory devices contain two or more memory cells on a semiconductor substrate and bit line dielectrics between the memory cells. The bit line dielectrics can extend into the semiconductor. The memory cell contains one or more charge storage nodes, a first poly gate, a pair of first bit lines, and a pair of second bit lines. The second bit line can be formed at a higher energy level, a higher concentration of dopants, or a combination thereof compared to an energy level and a concentration of dopants of the first bit line.

Abstract: A method is disclosed for the definition of the poly-1 layer in a semiconductor wafer. A non-critical mask is used to recess field oxides in the periphery prior to poly-1 deposition by an amount equal to the final poly-1 thickness. A complimentary non-critical mask is used to permit CMP of the core to expose the tops of core oxide mesas from the shallow isolation trenches.

Abstract: The present invention details a method which characterizes an STI fabrication process, and more particularly provides information relating to a variation in the STI sidewall profile between trenches in a middle portion of an array and a trench on an outer portion thereof. The method comprises forming two STI arrays with an STI fabrication process, forming a conductive layer over each array, biasing each conductive layer and determining a current associated therewith. The two current are then utilized to ascertain the variation of interest.
