Patent number: 11177065Abstract: Examples herein include thermally conductive pathways for glass substrates such as used by passive on glass devices that may be used to enhance the thermal conductivity of an integrated POG device. By using a thermally conductive material for passivation of the device pathways during manufacturing, the device pathways may be able to conduct heat away from the device. For example, by using a selected poly (p-phenylene benzobisoxazole) (PBO) based material (e.g., poly-p-phenylene-2, 6-benzobisoxazole) instead of conventional polyimide (PI) materials during a Cu pattern passivation process, the overall thermal performance of the device, may be enhanced.Type: GrantFiled: March 30, 2020Date of Patent: November 16, 2021Assignee: QUALCOMM IncorporatedInventors: Kai Liu, Xiaoju Yu, Xia Li, Bin Yang
