  • Publication number: 20170103813
    Abstract: Disclosed is an effective programming method for non-volatile flash memory including memory cells, each formed of a select transistor and a floating transistor. The method includes imposing a positive voltage onto a control gate of the floating transistor as a word line, supplying a zero voltage to a triple well, a deep N well, and a select gate of the select transistor to turn off the select transistor, and finally providing a moderate positive voltage to a drain of the control transistor. Owing to the junction band-to-band tunneling effect, the electron of the hole-electron pair generated between the junction of the bit line and the triple well leaps to the floating gate of the floating transistor driven by the positive electric field to form a higher threshold voltage for the memory cell such that the process of programming is accomplished.

  • Publication number: 20030190873
    Abstract: A chemical-mechanical polishing platform that comprises a polishing table, a wafer carrier, a polishing pad, a slurry supplier, a conditioner, and a means for cleaning the polishing pad. With respect to in-situ or ex-situ chemical-mechanical polishing, the wafer carrier, conditioner, and means for cleaning the polishing pad are adequately disposed above the polishing pad. The chemical-mechanical polishing is performed by rotation of the polishing pad; the region of the polishing pad that has polished the wafer then passes sequentially through the conditioner, the means for cleaning that removes diamond particles that may drop on the polishing pad, and through the slurry supplier that provides adequate slurry such that the polishing process can be repeated without scraping damage of the wafer. The means for cleaning of the present invention can have any shapes adapted to remove diamond particles on the polishing pad, such as circular or cylindrical brush sweeper.
