  • Patent number: 7374980
    Abstract: A field effect transistor and a method of fabricating the field effect transistor. The field effect transistor includes: a silicon body, a perimeter of the silicon body abutting a dielectric isolation; a source and a drain formed in the body and on opposite sides of a channel formed in the body; and a gate dielectric layer between the body and an electrically conductive gate electrode, a bottom surface of the gate dielectric layer in direct physical contact with a top surface of the body and a bottom surface the gate electrode in direct physical contact with a top surface of the gate dielectric layer, the gate electrode having a first region having a first thickness and a second region having a second thickness, the first region extending along the top surface of the gate dielectric layer over the channel region, the second thickness greater than the first thickness.

  • Publication number: 20080085456
    Abstract: A mask, a method for creating a mask, and a method for irradiating a substrate through use of the mask. Creating the mask establishes the mask by designing the mask, forming the mask, or both designing and forming the mask. Creating the mask includes receiving a specified target transmittance (TS) of the substrate with respect to radiation propagated from a radiation source and transmitted through the mask with spatial selectivity in accordance with a spatially varying transmissivity (TM) of the mask with respect to the radiation. The mask is disposed between the radiation source and the substrate. The mask includes transparent portions and reflective portions distributed within the transparent portions. The first radiation after having passed through the mask is transmitted into the substrate in accordance with a spatially varying reflectance (R) of the substrate such that TM*(1?R) is about equal to TS.

  • Publication number: 20080070422
    Abstract: A method for configuring J electromagnetic radiation sources (J?2) to serially irradiate a substrate. Each source has a different function of wavelength and angular distribution of emitted radiation. The substrate includes a base layer and I stacks (I?2; J?I) thereon. Pj denotes a same source-specific normally incident energy flux on each stack from source j. In each of I independent exposure steps, the I stacks are concurrently exposed to radiation from the J sources. Vi and Si respectively denote an actual and target energy flux transmitted into the substrate via stack i in exposure step i (i=1, . . . , I). t(i) and Pt(i) are computed such that: Vi is maximal through deployment of source t(i) as compared with deployment of any other source for i=1, . . . , I; and an error E being a function of |V1?S1|, |V2?S2|, . . . , |VI?SI| is about minimized with respect to Pi (i=1, . . . , I).
