Abstract:
1. A method for integrally forming a capacitor and a microcoil on a semiconductor substrate, the method comprising: depositing and patterning a dielectric layer on the substrate; depositing and patterning a sacrificial layer on the substrate; depositing and patterning conductive material on the semiconductor substrate, the patterned conductive material including a windings portion of the microcoil, an overlapping electrode portion of the capacitor and a support portion for the electrode portion of the capacitor; depositing and patterning a polymer layer on the semiconductor substrate; removing an exposed portion of the conductive material exposed by the patterned polymer layer to release a portion of the conductive pattern from the semiconductor substrate to form out-of-plane windings of the microcoil; depositing a second conductive material on exposed portions of the conductive material; and removing the sacrificial layer.
