Claim 9:
10. A photonic integrated circuit component, comprising:
a semiconductor substrate;
an optical waveguide disposed over the semiconductor substrate;
a heater disposed over the optical waveguide, the heater comprising a heating portion overlapping with the optical waveguide, pad portions disposed aside of the heating portion and tapered portions, wherein each of the tapered portions respectively comprises a first end connecting to the pad portions and a second end opposite to the first end, and the first end is wider than the second end; and
an interconnect structure disposed over the optical waveguide and the heater, and the heater being between the interconnect structure and the optical waveguide;
an interlayer dielectric layer covering the optical waveguide and the heater; and
conductive contacts embedded in the interlayer dielectric layer and electrically connected to the pad portions of the heater.
