Claim Text:
1. A method of doping a substrate with first and second pluralities of dopant particles, the method comprising: exposing the substrate comprising an organic polymer to a first layer comprising a first plurality of dopant particles, wherein a thermal conductivity of the organic polymer is less than 5 Wm irradiating the substrate and the first layer to an energy source operating at an operating frequency such that the first plurality of dopant particles of the first layer diffuse into the organic polymer of the substrate; continuing the irradiating for a first desired time to achieve a first depth of penetration of the first plurality of dopant particles into the organic polymer; exposing the substrate to a second layer comprising a second plurality of dielectric dopant particles, wherein the lossiness organic polymer that is less than a lossiness of the second plurality of dopant particles; irradiating the substrate and the second layer to an energy source operating at the operating frequency such that the second plurality of dopant particles of the second layer diffuse into the organic polymer of the substrate; and continuing the irradiating for a second desired time such that, the second plurality of particles, having a composition that is different from a composition of particles of the first plurality achieve a second depth of penetration that is different from the first depth of penetration.
