  • Integrating high-voltage CMOS devices with low-voltage CMOS
    Patent number: 7781843
    Abstract: High-voltage CMOS devices and low-voltage CMOS devices are integrated on a common substrate by forming a sacrificial film over at least active device areas, lithographically defining device active regions of the high-voltage CMOS devices, implanting dopants selectively through the sacrificial film into the lithographically defined device active regions of the high-voltage CMOS devices, diffusing the implanted dopants, removing the sacrificial film, and subsequently forming low-voltage CMOS devices.

  • Method and apparatus for driver circuit to provide a desired voltage level to a device
    Patent number: 7486588
    Abstract: A method includes a row precharge voltage applied to a node and a column voltage that is set. A row enable signal is pulsed to a switching device coupled between the node and the column voltage to cause the node voltage to be lowered to a desired level.

  • Method and apparatus for driver circuit in a MEMS device
    Patent number: 7203111
    Abstract: An embodiment includes a first semiconductor element coupled between a precharge signal and a node, the first semiconductor element to allow current to flow from the precharge signal to the node when a positive voltage is present on the precharge signal, and a switching device coupled between the node and a voltage signal, the switching device to allow current flow between the node and the voltage signal when an enable signal is asserted.

  • Methods and devices for modulating fluid flow in a micro-fluidic channel
    Publication number: 20060243934
    Abstract: The present invention is drawn to a method for modulating fluid flow in a micro-fluidic channel, comprising the step of applying heat to a valve of a micro-fluidic channeling device. The valve can include an elastically resilient portion having a first configuration prior to application of heat and a second configuration after application of heat. In one aspect, the first configuration provides an open valve configuration and the second configuration provides a closed valve configuration. In another aspect, the first configuration provides a closed valve configuration and the second configuration provides an open valve configuration.
