    摘要: A method for processing a wafer having microelectromechanical system structures at the first main surface includes applying a masking material at the second main surface and structuring the masking material to obtain a plurality of masked areas and a plurality of unmasked areas at the second main surface. The method further includes anisotropically etching the wafer from the second main surface at the unmasked areas to form a plurality of recesses. The masking material is then removed at least at some of the masked areas to obtain previously masked areas. The method further includes anisotropically etching the wafer from the second main surface at the unmasked areas and the previously masked areas to increase a depth of the recesses and reduce a thickness of the wafer at the previously masked areas.

    摘要: Some embodiments of the present disclosure relate to an infrared (IR) opto-electronic sensor having a silicon waveguide implemented on a single silicon integrated chip. The IR sensor has a semiconductor substrate having a silicon waveguide extends along a length between a radiation input conduit and a radiation output conduit. The radiation input conduit couples radiation into the silicon waveguide, while the radiation output conduit couples radiation out from the silicon waveguide. The silicon waveguide conveys the IR radiation from the radiation input conduit to the radiation output conduit at a single mode. As the radiation is conveyed by the silicon waveguide, an evanescent field is formed that extends outward from the silicon waveguide to interact with a sample positioned between the radiation input conduit and the radiation output conduit.
