Patent number: 12211811Abstract: An electronic device includes a substrate, an electronic component, a first interposing layer and a second interposing layer. The substrate is non-planar and the substrate includes a first substrate pad and a second substrate pad. The electronic component includes a first component pad and a second component pad corresponding to the first substrate pad and the second substrate pad respectively. When the first component pad contacts the first substrate pad, a height difference exists between the second component pad and the second substrate pad. The first interposing layer connects between the first component pad and the first substrate pad. The second interposing layer connects between the second component pad and the second substrate pad. A thickness difference between the first interposing layer and the second interposing layer is 0.5 to 1 time the height difference.Type: GrantFiled: March 24, 2022Date of Patent: January 28, 2025Assignee: Industrial Technology Research InstituteInventors: Yu-Ming Peng, Chien-Chou Tseng, Chih-Chia Chang, Kuan-Chu Wu, Yu-Lin Hsu

Patent number: 10757804Abstract: A flexible hybrid electronic (FHE) system includes a carrier, a first redistribution structure on the carrier, a first device on the first redistribution structure, and an encapsulation layer encapsulating the first device. The carrier has a first Young's modulus Y1. The first redistribution structure has a second Young's modulus Y2. The first device and a portion of the encapsulation layer form a top surface of the first redistribution structure to a top surface of the first device is a first portion having a third Young's modulus Y3. The other portion of the encapsulation layer from the top surface of the first device to a top surface of the encapsulation layer is a second portion having a fourth Young's modulus Y4. A ratio of Y3/Y4 is between 1.62 and 1.98; a ratio of Y3/Y2 is between 0.18 and 0.22; and a ratio of Y3/Y1 is between 280.62 and 342.98.Type: GrantFiled: March 11, 2020Date of Patent: August 25, 2020Assignee: Industrial Technology Research InstituteInventors: Yu-Ming Peng, Kuan-Chu Wu, Kai-Ming Chang, Chen-Tsai Yang
