    摘要: A method and apparatus for testing semiconductors comprising shallow trench isolation (STI) edge structures. An edge intensive shallow trench isolation structure (500) is coupled to a voltage source (310) and a current profile is recorded. A planar structure (600) on the same wafer is coupled to a voltage source and a current profile is recorded. A comparison of current profiles obtained for the two types of structures may indicate the presence and/or extent of STI corner effects. More specifically, a steeper slope for a normalized current versus time plot for an STI edge intensive structure (500) compared to a slope of a normalized plot of a planar structure (600) is indicative of an increased rate of electron trapping in STI corners, which may indicate that the STI corners are too thin. In this novel manner, STI corner thickness is observed in a non-destructive, electrical test process, resulting in higher quality and greater reliability of semiconductors using STI processes.

An edge intensive shallow trench isolation structure (500) is coupled to a voltage source (310) and a current versus voltage profile is recorded. A planar structure (600) on the same wafer is coupled to a voltage source and a current versus voltage profile is recorded. An electrical stress is applied to both structures. Additional current profiles of each structure are obtained after the electrical stress. A comparison of difference current profiles obtained for the two types of structures may indicate the presence and/or the extent of STI corner effects. More specifically, a value for a normalized gate current difference for an STI edge intensive structure (500) greater than normalized gate current difference of a planar structure (600) is indicative of an increased rate of electron trapping in STI corners, which may indicate that the STI corners are too thin. In this novel manner, STI corner thickness may be observed in a non-destructive, electrical test process, resulting in higher quality and greater reliability of semiconductors using STI processes.

    摘要: Commonly, read times of a memory line are slowed due to voltage overshoot and/or voltage undershoot. To eliminate these problems, a control component can manage voltage while a leakage component manages timing of voltage. This allows for a line pre-charge that produces increase read times. The control component can implement as a variable resistor that modifies value to compensate for temperature. The leakage component can include a capacitor configuration that allows voltage to pass.

    摘要: Manners for transferring information within a flash memory device across a memory array are described. A controller retrieves information from a storage unit and then a decoder decodes the information. The information is set across a series of bitlines through a pass gate to a second controller. The bitlines are both associated with the storage unit as well as bitlines associated with other storage units. A series of transistors is associated with each bitline. Different transistors are active based on if the bitlines are associated with the currently used storage unit.

    摘要: A voltage regulator comprises resistor elements that mitigate variations in a program voltage (VPROG). In particular, the resistors allow copies of the voltage regulator to be fabricated more consistently across a semiconductor substrate. As such, variations in respective program voltages applied to different bitlines of a memory arrangement are mitigated. This mitigates yield loss as more devices perform as desired, thus necessitating fewer discards.
