VERTICALLY INTEGRATED DEVICE STACK INCLUDING SYSTEM ON CHIP AND POWER MANAGEMENT INTEGRATED CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240105762 titled 'VERTICALLY INTEGRATED DEVICE STACK INCLUDING SYSTEM ON CHIP AND POWER MANAGEMENT INTEGRATED CIRCUIT
Simplified Explanation
The semiconductor device described in the patent application consists of a package substrate, a system-on-chip (SoC) die, and a power management integrated circuit (PMIC) die arranged in a vertical stack. The SoC die is placed on the first surface of the package substrate, while the PMIC die is attached to the second surface of the package substrate. The PMIC die is connected to the SoC die through via connectors on the package substrate, providing DC power to the SoC die via DC connectors also on the package substrate. The PMIC die includes thin film inductors corresponding to the DC connectors, located on its surface adjacent to the package substrate.
