Nanoparticle structure and process for manufacture
A method for forming nanoparticles includes forming a stack of alternating layers including a first material disposed between a second material. The stack of alternating layers is patterned to form pillars. A dielectric layer is conformally deposited over the pillars. The pillars are annealed in an oxygen environment to modify a shape of the first material of the alternating layers. The dielectric layer and the second material are etched selectively to the first material to form nanoparticles from the first material.
