In the first step, a localized platinum film, less than 10 .ANG. high, is deposited. Subsequently the whole surface is covered by a few microns of Cu(HCOO)2.2H2O. Heating to about 70 Deg causes the formate to decomp. exclusively where the surface had been seeded with the thin film of platinum clusters. Line resistivities of about twice that of pure bulk copper can be obtained in this way. In principle this method should permit direct writing of metal stripes at very high speeds and good spatial resoln.7440-06-4 (Platinum) Role: RCT (Reactant)RACT (Reactant or reagent) (decompn. of copper formate on clusters ofin selective growth of copper conductive lines); 544-19-4 (Copper formate) Role: RCT (Reactant)RACT (Reactant or reagent) (decompn. ofocopper film growth platinum cluster; resistivity copper line selective growthtext::journal::journal article::research article
