Patent ID: 10304750

Abstract:
A package structure is provided, which includes: a first polymer layer with a first surface; a second polymer layer with a second surface on the first polymer layer; a circuit device with opposing third and fourth surfaces, the circuit device disposed on the second polymer layer and with multiple metal pads on the fourth surface; a first high-filler dielectric layer enclosing the circuit device and the second polymer layer and covering the first polymer layer; a first conductive wiring formed on the first high-filler dielectric layer; a first conductive passage formed in the first high-filler dielectric layer and connecting the first conductive wiring to the metal pads; a second high-filler dielectric layer enclosing the first conductive wiring and covering the first high-filler dielectric layer; and a second conductive passage formed in the second high-filler dielectric layer and connecting the first conductive wiring to an external circuit.
