    摘要: A method includes placing a first wafer onto a surface of a first wafer chuck, the first wafer chuck including multiple first profile control zones separated by one or more shared flexible membranes. The method also includes setting a first profile of the surface of the first wafer chuck. Setting a first profile of the surface of the first wafer chuck includes adjusting a first volume of a first profile control zone of the multiple first profile control zones. Setting a first profile of the surface of the first wafer chuck also includes adjusting a second volume of a second profile control zone of the multiple first profile control zones, the first volume of the first profile control zone being adjusted independently from the second volume of the second profile control zone, and the second adjustable volume encircling the first adjustable volume.

    摘要: A system and method for forming pixels in an image sensor is provided. In an embodiment, a semiconductor device includes an image sensor including a first pixel region and a second pixel region in a substrate, the first pixel region being adjacent to the second pixel region. A first anti-reflection coating is over the first pixel region, the first anti-reflection coating reducing reflection for a first wavelength range of incident light. A second anti-reflection coating is over the second pixel region, the second anti-reflection coating reducing reflection for a second wavelength range of incident light that is different from the first wavelength range.
