  • Patent number: 9647155
    Abstract: The disclosure provides a photo-detection device for use in long-wave infrared detection and a method of fabrication. The device comprises a GaSb substrate, a photo absorbing layer comprising InAs/InAsSb superlattice type-II, a barrier layer comprising AlAsSb, and a contact layer comprising InAs/InAsSb superlattice type-II. The barrier layer is configured to allow minority carrier holes current flow while blocking majority carrier electrons current flow between the photo-absorbing and contact layers. The disclosure further provides a method of producing the photo-detector using photolithography which includes selective etching of the contact layer that stops on the top of the barrier so no etching is made to the barrier layer so the barrier may operate as a passivator too.

  • Patent number: 9627533
    Abstract: A silicon nitride cap on a gate stack is removed by etching with a fluorohydrocarbon-containing plasma subsequent to formation of source/drain regions without causing unacceptable damage to the gate stack or source/drain regions. A fluorohydrocarbon-containing polymer protection layer is selectively deposited on the regions that are not to be etched during the removal of the nitride cap. The ability to remove the silicon nitride material using gas chemistry, causing formation of a volatile etch product and protection layer, enables reduction of the ion energy to the etching threshold.
