Publication number: 20240136346Abstract: A semiconductor die package includes an inductor-capacitor (LC) semiconductor die that is directly bonded with a logic semiconductor die. The LC semiconductor die includes inductors and capacitors that are integrated into a single die. The inductors and capacitors of the LC semiconductor die may be electrically connected with transistors and other logic components on the logic semiconductor die to form a voltage regulator circuit of the semiconductor die package. The integration of passive components (e.g., the inductors and capacitors) of the voltage regulator circuit into a single semiconductor die reduces signal propagation distances in the voltage regulator circuit, which may increase the operating efficiency of the voltage regulator circuit, may reduce the formfactor for the semiconductor die package, may reduce parasitic capacitance and/or may reduce parasitic inductance in the voltage regulator circuit (thereby improving the performance of the voltage regulator circuit), among other examples.Type: ApplicationFiled: April 17, 2023Publication date: April 25, 2024Inventors: Chien Hung LIU, Yu-Sheng CHEN, Yi Ching ONG, Hsien Jung CHEN, Kuen-Yi CHEN, Kuo-Ching HUANG, Harry-HakLay CHUANG, Wei-Cheng WU, Yu-Jen WANG

Publication number: 20230058158Abstract: Aspects of the disclosure relate to an automated iterative predictive modeling computing platform that iteratively requests additional data from external data sources to iteratively generate a more accurate insurance premium estimation. In some instances, the automated iterative predictive modeling computing platform may generate an insurance premium estimation using affordable insurance data and using estimated data in place of missing data. If the insurance premium estimation does not meet predefined confidence thresholds, the automated iterative predictive modeling computing platform may retrieve additional data that is more expensive but also has a likelihood to generate a more accurate insurance premium estimation. This process may be repeated using different data sets from different external data sources until a sufficiently accurate insurance premium estimate is generated by the automated iterative predictive modeling computing platform.Type: ApplicationFiled: August 19, 2021Publication date: February 23, 2023Inventors: Dylan Wienke, Brian Paul Guntli, Vishal Krishna Varma, Chien-Hsun Yu, Yu Jen Liu
