  • Process for forming a porous silicon member in a crystalline silicon member
    Patent number: 6004450
    Abstract: Fabrication and use of porous silicon structures to increase surface area of heated reaction chambers, electrophoresis devices, and thermopneumatic sensor-actuators, chemical preconcentrates, and filtering or control flow devices. In particular, such high surface area or specific pore size porous silicon structures will be useful in significantly augmenting the adsorption, vaporization, desorption, condensation and flow of liquids and gasses in applications that use such processes on a miniature scale. Examples that will benefit from a high surface area, porous silicon structure include sample preconcentrators that are designed to adsorb and subsequently desorb specific chemical species from a sample background; chemical reaction chambers with enhanced surface reaction rates; and sensor-actuator chamber devices with increased pressure for thermopneumatic actuation of integrated membranes.
    Type: Grant
    Filed: September 30, 1998
    Date of Patent: December 21, 1999
    Assignee: The Regents of the University of California
    Inventors: M. Allen Northrup, Conrad M. Yu, Norman F. Raley
