    Abstract: The present disclosure relates to an image sensor having a photodiode surrounded by a back-side deep trench isolation (BDTI) structure, and an associated method of formation. In some embodiments, a plurality of pixel regions is disposed within an image sensing die and respectively comprises a photodiode configured to convert radiation into an electrical signal. The photodiode comprises a photodiode doping column with a first doping type surrounded by a photodiode doping layer with a second doping type that is different than the first doping type. A BDTI structure is disposed between adjacent pixel regions and extending from the back-side of the image sensor die to a position within the photodiode doping layer. The BDTI structure comprises a doped liner with the second doping type and a dielectric fill layer. The doped liner lines a sidewall surface of the dielectric fill layer.

    Abstract: In some embodiments, the present disclosure relates to a microelectromechanical system (MEMS) comb actuator including a comb structure. The comb structure includes a support layer having a first material and a plurality of protrusions extending away from a first surface of the support layer in a first direction. The plurality of protrusions are also made of the first material. The plurality of protrusions are separated along a second direction parallel to the first surface of the support layer. The MEMS comb actuator may further include a dielectric liner structure that continuously and completely covers the first surface of the support layer and outer surfaces of the plurality of protrusions. The dielectric liner structure includes a connective portion that continuously connects topmost surfaces of at least two of the plurality of protrusions.

    Abstract: In some embodiments, a semiconductor fabrication tool is provided. The semiconductor fabrication tool includes a first processing zone having a first ambient environment and a second processing zone having a second ambient environment disposed at different location inside a processing chamber. A first exhaust port and a second exhaust port are disposed in the first and second processing zones, respectively. A first exhaust pipe couples the first exhaust port to a first individual exhaust output. A second exhaust pipe couples the second exhaust port to a second individual exhaust output, where the second exhaust pipe is separate from the first exhaust pipe. A first adjustable fluid control element controls the first ambient environment. A second adjustable fluid control element controls the second ambient environment, where the first adjustable fluid control element and the second adjustable fluid control element are independently adjustable.
