  • Publication number: 20120067971
    Abstract: A showerhead for film-depositing vacuum equipment having an effect shortening the length of injection tubes for a reactive gas is presented. The injection tubes extend from the bottom of a reactive gas showerhead module, and two different kinds of reactive gases are mixed with an injection support gas within a reactive showerhead module so as to inject the mixed gas. The showerhead for film-depositing vacuum equipment includes the reactive gas showerhead module above a cooling jacket and a purge gas showerhead module above the reactive gas showerhead module. The injection tubes of the reactive gas showerhead module pass through the cooling jacket disposed below the reactive gas showerhead module, and the injection tubes of the purge gas showerhead module pass through the reactive gas showerhead module disposed below the purge gas showerhead module, thereby enabling the purge gas to flow into a purge gas redistribution space defined above the cooling jacket.

  • Patent number: 8040297
    Abstract: An emission control driver that applies an emission control signal for controlling an emission operation of a pixel circuit is provided. The emission control driver includes an emission control circuit with a plurality of transistors and a capacitor placed between a positive power supply voltage and a negative power supply voltage.

  • Publication number: 20110235412
    Abstract: A system and methodology that can minimize disturbance during an AC operation associated with a memory, such as, program, read and/or erase, is provided. The system pre-charges all or a desired subset of the bit lines in a memory array to a specified voltage, during an AC operation to facilitate reducing AC disturbances between neighboring cells. A pre-charge voltage can be applied to all bit lines in a block in the memory array, or to bit lines associated with a selected memory cell and neighbor memory cells adjacent to the selected memory cell in the block. The system ensures that source and drain voltage levels can be set to desired levels at the same or substantially the same time, while selecting a memory cell. This can facilitate minimizing AC disturbances in the selected memory cell during the AC operation.
