    摘要: The present invention relates to a method for improving an interface of a semiconductor device. The method comprises providing a first and second substrate having an oxidized region, and establishing a first loading position in a first process chamber. The first and second substrates are consecutively inserted into the first process chamber and generally simultaneously processed, wherein the oxidized region is reduced by exposure to a first plasma. The first and second substrates are then consecutively removed and the first substrate is inserted into a second process chamber and subsequently processed. The second substrate is then inserted into the second process chamber and the first and second substrates are simultaneously processed. The first substrate is the removed, and the second substrate is processed again. According to one exemplary aspect, the first and second substrates are exposed to a first temperature in the first process chamber for approximately half the time the first and second substrates are exposed to a higher second temperature in the second process chamber while maintaining throughput of substrates.

    摘要: One aspect of the invention provides a method of forming a semiconductor device (100). One aspect includes forming transistors (120, 125) on a semiconductor substrate (105), forming a first interlevel dielectric layer (165) over the transistors (120, 125), and forming metal interconnects (170, 175) within the first interlevel dielectric layer (165). A carbon-containing gas is used to form a silicon carbon nitride (SiCN) layer (180) over the metal interconnects (170, 175) and the first interlevel dielectric layer (165) within a deposition tool. An adhesion layer (185) is formed on the SiCN layer (180), within the deposition tool, by discontinuing a flow of the carbon-containing gas within the deposition chamber. A second interlevel dielectric layer (190) is formed over the adhesion layer (185).

    摘要: A novel method of modulating the motion or displacement of function units in MEMS (micro-electro-mechanical-system) devices (or MEMS motion transducers) is described. This method generates small vertical displacement of one MEMS component (activation component) in the device and effectively translates that displacement into the displacement of another MEMS component (function unit) in the same device in an in-plan direction that is perpendicular to the direction of the vertical displacement of activation component. The activation component has a large surface area of electrostatic interaction with its interacting electrode, capable of generating large activation force at small voltages. Therefore this method makes it effective to modulate the motion or displacement of the function unit of MEMS motion transducers in an in-plan direction at low voltages. Specific designs of MEMS motion transducers employing this method are disclosed.
