  • Publication number: 20190172907
    Abstract: An integrated circuit is formed by forming an isolation trench through at least a portion of an interconnect region, at least 40 microns deep into a substrate of the integrated circuit, leaving at least 200 microns of substrate material under the isolation trench. Dielectric material is formed in the isolation trench at a substrate temperature no greater than 320° C. to form an isolation structure which separates an isolated region of the integrated circuit from at least a portion of the substrate. The isolated region contains an isolated component. The isolated region of the integrated circuit may be a region of the substrate, and/or a region of the interconnect region. The isolated region may be a first portion of the substrate which is laterally separated from a second portion of the substrate. The isolated region may be a portion of the interconnect region above the isolation structure.

  • Publication number: 20190109245
    Abstract: An integrated circuit that includes a substrate, a photodiode, and a Fresnel structure. The photodiode is formed on the substrate, and it has a p-n junction. The Fresnel structure is formed above the photodiode, and it defines a focal zone that is positioned within a proximity of the p-n junction. In one aspect, the Fresnel structure may include a trench pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In another aspect, the Fresnel structure may include a wiring pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In yet another aspect, the Fresnel structure may include a transparent dielectric pattern that functions as a refractive means for redirecting and concentrating incident photons to the focal zone.

  • Publication number: 20180179054
    Abstract: An apparatus includes a lens material forming a lens. The apparatus also includes a piezoelectric capacitor over the lens material, where the piezoelectric capacitor is configured to change a shape of the lens material in response to a voltage across the piezoelectric capacitor to thereby change a focus of the lens. The apparatus further includes at least one stress compensation ring over a portion of the lens material and over at least a portion of the piezoelectric capacitor. The at least one stress compensation ring is configured to at least partially reduce bending of the lens material caused by stress on or in the lens material.

  • Patent number: 9793106
    Abstract: It has been discovered that poor TDDB reliability of microelectronic device capacitors with organic polymer material in the capacitor dielectric is due to water molecules infiltrating the organic polymer material when the microelectronic device is exposed to water vapor in the operating ambient. Water molecule infiltration from water vapor in the ambient is effectively reduced by a moisture barrier comprising a layer of aluminum oxide formed by an atomic layer deposition (ALD) process. A microelectronic device includes a capacitor with organic polymer material in the capacitor dielectric and a moisture barrier with a layer of aluminum oxide formed by an ALD process.

  • Publication number: 20150376000
    Abstract: A method includes forming a piezoelectric optical micro-electromechanical system (MEMS) device having a piezoelectric capacitor over a lens material. The lens material forms a lens, and the piezoelectric capacitor is configured to change a shape of the lens material in order to change a focus of the lens. The piezoelectric capacitor includes first and second electrodes separated by at least one piezoelectric material. The method also includes performing a first anneal on the piezoelectric optical MEMS device in nitrogen gas and performing a second anneal on the piezoelectric optical MEMS device in oxygen gas after performing the first anneal. The method further includes depositing a protective oxide layer over the lens material and the piezoelectric capacitor after performing the second anneal. The first anneal in the nitrogen gas causes the piezoelectric optical MEMS device to be substantially free of discharge defects.
