    摘要： Disclosed herein is a method of forming a silicon gate stack onto a silicon substrate for a silicon device. The method of forming the silicon gate stack comprises the steps of growing an oxide layer onto the silicon substrate, depositing a thin layer of silicon to form a thin layer of silicon over the oxide layer, depositing a thick layer of silicon over the thin layer of silicon, and introducing impurities into only the thick layer of silicon to form a silicon gate whereby the silicon gate includes the thin layer of silicon and the thick layer of silicon having the impurities. The impurities being introduced with a concentration, the impurities concentration and the thick layer thickness impeding an encroachment by the oxide layer into the silicon gate during application of a protective screen oxide layer around the silicon gate stack.

    摘要： A method of providing thick and thin oxide structures reduces step changes between a core region and a peripheral region on an integrated circuit. Thin LOCOS structures are provided in a core region of a flash memory device, and thick LOCOS structures are provided in a peripheral region of the flash memory device. The device and process are not as susceptible to "race track" problems, "oxide" bump problems, and "stringer" problems. The process utilizes two separate nitride or hard mask layers.

    摘要： A series select transistor and a source select transistor are connected in series at the end of a NAND string of floating gate data storage transistors. The floating gates, the series select gate, and the source select gate are all preferably formed of polysilicon. The same tunnel oxide layer is used as gate oxide for the series select transistor and source select transistor as well as for the floating gate data storage transistors. Two layers of polysilicon in the series select gate and the source select gates are tied together. The series select transistor is tied to the last transistor in the NAND string. The source select transistor is tied to the array Vss supply. In order to program inhibit a specific NAND cell during the programming of another NAND cell, the gate of the series select transistor is raised to Vcc, while the gate of the source select transistor is held to ground. The two transistors in series are able to withstand a much higher voltage at the end of the NAND string without causing gated-diode junction or oxide breakdown in either the series or the source select transistor.

    摘要： A system and method for micromanipulating samples are described to perform automatic, reliable, and high-throughput sample microinjection of foreign genetic materials, proteins, and other molecules, as well as drawing genetic materials, proteins, and other molecules from the sample. The system and method overcome the problems inherent in traditional manual micromanipulation that is characterized by poor reproducibility, human fatigue, and low throughput. The present invention is particularly suited for adherent cell microinjection but can be readily extended to aspiration, isolation, and electrophysiological measurements of microorganisms, unicellular organisms, or cells.
