  • Patent number: 9728667
    Abstract: A device that detects single optical and radiation events and that provides improved blue detection efficiency and lower dark currents than prior silicon SSPM devices. The sensing element of the devices is a photodiode that may be used to provide single photon detection through the process of generating a self-sustained avalanche. The type of diode is called a Geiger photodiode or signal photon-counting avalanche diode. A CMOS photodiode can be fabricated using a “buried” doping layer for the P-N junction, where the high doping concentration and P-N junction is deep beneath the surface, and the doping concentration at the surface of the diode may be low. The use of a buried layer with a high doping concentration compared to the near surface layer of the primary P-N junction allows for the electric field of the depletion region to extend up near the surface of the diode. With a low doping concentration through the bulk of the diode, the induced bulk defects are limited, which may reduce the dark current.

  • Patent number: 9722052
    Abstract: A method of forming semiconductor fins is provided. Sacrificial fins are provided on a surface of substrate. A hard mask layer, formed around the sacrificial fins and the gaps therebetween, is made coplanar with a topmost surface of the sacrificial fins. A fin cut mask then covers a portion of the sacrificial fins and partly covers a sacrificial fin. Trenches are formed in the hard mask layer by removing sacrificial fins not covered by the fin cut mask and that portion of the sacrificial fin not partly covered by the fin cut mask. Spacers are formed on the sidewalls of the trenches and a plug is formed in the trench formed by removing that portion of the sacrificial fin not partly covered by the fin cut mask. Semiconductor fins are grown epitaxially in the trenches having the spacers from the exposed surface of the substrate upward.

  • Patent number: 9673091
    Abstract: Disclosed is a method of forming back end of the line (BEOL) metal levels with improved dielectric capping layer to metal wire adhesion. The method includes process step(s) designed to address dielectric capping layer to metal wire adhesion, when the metal wire(s) in a given metal level are relatively thick. These process step(s) can include, for example: (1) selective adjustment of the deposition tool used to deposit the dielectric capping layer onto metal wires based on the pattern density of the metal wires in order to ensure that those metal wires actually achieve a temperature between 360° C.-400° C.; and/or (2) deposition of a relatively thin dielectric layer on the dielectric capping layer prior to formation of the next metal level in order to reduce the tensile stress of the metal wire(s) below without causing delamination. Also disclosed is an IC chip formed using the above-described method.

  • Patent number: 9653664
    Abstract: Disclosed is a chip substrate. The chip substrate includes: conductive portions laminated in one direction to constitute the chip substrate; insulation portions alternately laminated with the conductive portions to electrically isolate the conductive portions; a cavity formed at a predetermined depth in a recessed shape in a region including the insulation portions on an upper surface of the chip substrate; and a groove portion disposed outside the cavity in a spaced-apart relationship with the cavity and formed at a predetermined depth in a recessed shape. According to the present invention, an adhesive agent is applied in a groove portion formed in advance. It is therefore possible to prevent the adhesive agent from being exposed to the light emitted from optical elements and to prevent the adhesive agent from being denatured. This makes it possible to enhance the reliability of lens bonding. Furthermore, there is no need to use an expensive resistant adhesive agent.
