Assignee:
Western Digital (Fremont), LLC - Fremont CA
International Classification:
G11B 5/33
US Classification:
428800, 428810, 428812, 428815
Abstract:
A method for fabricating a magnetic transducer having an air-bearing surface (ABS). An underlayer having a first and second regions and a bevel connecting these regions is provided. The first region is thicker and closer to the ABS than the second region. An intermediate layer conformal with the underlayer is provided. A hard mask layer having a top surface perpendicular to the ABS is formed on the intermediate layer. Part of the hard mask and intermediate layers are removed to provide a trench. The trench has a bottom surface and sidewalls having a first angle between the bottom surface and the intermediate layer and a second angle corresponding to the hard mask layer. A pole is provided in the trench. The pole has a pole tip, a yoke distal, and a bottom bevel. At least the yoke includes sidewalls having sidewall angles corresponding to the first and second angles.

Inventors:
Lingyun Miao - Fremont CA, US
Sarp Satir - San Francisco CA, US
International Classification:
G01N 29/24
B06B 1/02
Abstract:
An ultrasound device is described. The ultrasound device comprises a capacitive micromachined ultrasonic transducer (CMUT). The CMUT comprises a membrane, a substrate, a cavity disposed between the membrane and the substrate, wherein the cavity comprises a bottom surface adjacent to the substrate, and non-uniform pedestals protruding from the bottom surface of the cavity into the cavity and towards the membrane.

US Patent:
20210361260, Nov 25, 2021
Filed:
May 21, 2021
Appl. No.:
17/326938
