Publication number: 20220029092Abstract: Aspects of the present technology are directed toward Integrated Circuits (IC) including a plurality of trenches disposed in a substrate about a set of silicide regions. The trenches can extend down into the substrate below the set of silicide regions. The silicide regions can be formed by implanting metal ions into portions of a substrate exposed by a mask layer with narrow pitch openings. The trenches can be formed by selectively etching the substrate utilizing the set of silicide regions as a trench mask. An semiconductor material with various degree of crystallinity can be grown from the silicide regions, in openings that extend through subsequently formed layers down to the silicide regions.Type: ApplicationFiled: August 16, 2021Publication date: January 27, 2022Inventors: Kuk-Hwan Kim, Dafna Beery, Marcin Gajek, Michail Tzoufras, Kadriye Deniz Bozdag, Eric Ryan, Satoru Araki, Andy Walker

Publication number: 20200353166Abstract: A fluid sensing apparatus and method for detecting pressure and the presence of bubbles within a fluid tube. The fluid sensor comprises a housing configured to receive a portion of the tube and to house the pressure sensor and the ultrasonic transmitter. The pressure sensor is positioned adjacent the tube and is configured to receive a pressure sensor signal, which correlates to a detected pressure differential within the tube. A controller transmits a drive signal to the ultrasonic transmitter, which emits ultrasonic waves through a portion of the tube and to the pressure sensor. The pressure sensor receives both the ultrasonic waves and a pressure sensor signal, and subsequently transmits an output signal to the controller. In the presence of a pressure differential or a bubble within the tube, the output signal will exhibit a DC shift or a distortion of its signal characteristics, respectively.Type: ApplicationFiled: May 10, 2019Publication date: November 12, 2020Inventors: Andy Walker Brown, Adam D.
