  • Publication number: 20240300808
    Abstract: Described herein are manufacturing techniques for achieving stress isolation in microelectromechanical systems (MEMS) devices that involve isolation trenches formed from the backside of the substrate. The techniques described herein involve etching a trench in the bottom side of the substrate subsequent to forming a MEMS platform, and processing the MEMS platform to form a MEMS device on the top side of the substrate subsequent to etching the trench.

  • Patent number: 12087713
    Abstract: Gallium nitride-based monolithic microwave integrated circuits (MMICs) can comprise aluminum-based metals. Electrical contacts for gates, sources, and drains of transistors can include aluminum-containing metallic materials. Additionally, connectors, inductors, and interconnect devices can also comprise aluminum-based metals. The gallium-based MMICs can be manufactured in complementary metal oxide semiconductor (CMOS) facilities with equipment that produces silicon-based semiconductor devices.

  • Publication number: 20240253979
    Abstract: A stress-isolated microelectromechanical systems (MEMS) device and a method of manufacture of the stress-isolated MEMS device are provided. MEMS devices may be sensitive to stress and may provide lower performance when subjected to stress. A stress-isolated MEMS device may be manufactured by etching a trench and/or a cavity in a first side of a substrate and subsequently forming a MEMS device on a surface of a platform opposite the first side of the substrate. Such a stress-isolated MEMS device may exhibit better performance than a MEMS device that is not stress-isolated. Moreover, manufacturing the MEMS device by first forming a trench and cavity on a backside of a wafer, before forming the MEMS device on a suspended platform, provides increased yield and allows for fabrication of smaller parts, in at least some embodiments.
