    Abstract: According to an exemplary embodiment, a semiconductor die including at least one deep silicon via is provided. The deep silicon via comprises a deep silicon via opening that extends through at least one pre-metal dielectric layer of the semiconductor die, at least one epitaxial layer of the semiconductor die, and partially into a conductive substrate of the semiconductor die. The deep silicon via further comprises a conductive plug situated in the deep silicon via opening and forming an electrical contact with the conductive substrate. The deep silicon via may include a sidewall dielectric layer and a bottom conductive layer. A method for making a deep silicon via is also disclosed. The deep silicon via is used to, for example, provide a ground connection for power transistors in the semiconductor die.

    Abstract: A light sensor having a chemically resistant and robust reflector stack is disclosed. The reflector stack is formed over a substrate, and includes an adhesion layer, a patterned reflector layer over the adhesion layer, and a smoothing layer over the patterned reflector layer. The patterned reflector layer has a substantially flat top surface. A conformal passivation layer covers the reflector stack. An absorbing layer is situated above the reflector stack and separated from the reflector stack. The absorbing layer is supported by vias over the substrate. The absorbing layer is connected to at least one resistor, where a resistance of the at least one resistor varies in response to light absorbed by the absorbing layer. The vias are disposed on via landing pads on the substrate.
