Laser-Activated Metal Deposition.
Abstract
A process to selectively deposit copper on polyimide was developed. Laser irradiation of organometallic palladium compounds with a CW argon ion laser at 351 nm was used to selectively deposit catalytic amounts of palladium on polyimide. Subsequent immersion of the irradiated samples in an electroless copper solution resulted in selective copper deposition. Since only a few monolayers of palladium were needed to catalyze the electroless copper process, fast writing speeds of up to 10 cm/s were achieved. Copper lines with 1.5 micro thickness and resistive of 3 mohm-cm were produced by this technique. (MJM)
