Patent number: 11598828Abstract: The present disclosure generally relates to a Wheatstone bridge array that has four resistors. Each resistor includes a plurality of TMR structures. Two resistors have identical TMR structures. The remaining two resistors also have identical TMR structures, though the TMR structures are different from the other two resistors. Additionally, the two resistors that have identical TMR structures have a different resistance area as compared to the remaining two resistors that have identical TMR structures. Therefore, the working bias field for the Wheatstone bridge array is non-zero.Type: GrantFiled: December 30, 2019Date of Patent: March 7, 2023Assignee: Western Digital Technologies, Inc.Inventors: Yuankai Zheng, Christian Kaiser, Zhitao Diao, Chih-Ching Hu, Chen-jung Chien, Yung-Hung Wang, Dujiang Wan, Ronghui Zhou, Ming Mao, Ming Jiang, Daniele Mauri

Patent number: 11201280Abstract: A Wheatstone bridge array comprising a tunneling magnetoresistive (TMR) sensor and a method for manufacturing is disclosed. The bottom lead for the TMR sensor has a very small surface roughness due to not only chemical mechanical planarization (CMP) but also due to forming the bottom lead from multiple layers. The multiple layers include at least a bottom first metal layer and a top second metal layer disposed on the first metal layer. The second metal layer generally has a lower surface roughness than the first metal layer. Additionally, the second metal layer has a slower polishing rate. Therefore, not only does the second metal layer reduce the surface roughness simply be being present, but the slower polishing rate enables the top second metal film to be polished to a very fine surface roughness of less than or equal to ˜2 Angstroms.Type: GrantFiled: December 30, 2019Date of Patent: December 14, 2021Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventors: Ronghui Zhou, Ming Mao, Ming Jiang, Yuankai Zheng, Chen-jung Chien, Yung-Hung Wang, Chih-Ching Hu
