Abstract
A method of etching a foil for use in an electrolytic capacitor utilizes a nanoimprinted optic to control the etch pattern. The optic is formed by creating a self-assembled monolayer (SAM) of hemispheres onto the surface of an optical quartz substrate. A laser is directed onto the optic while the foil underlies the optic, and the concentrated light source is used to effectively image an array of submicron spots. The resulting spots allow for controlled initiation of etch tunnels during a subsequent electrochemical etch of the foil, with the purpose of ultimately increasing foil capacitance through the increased surface area.
