A method of making a metallic pattern (250) comprises: depositing a layer
of photoresist (130) on a substrate (110); forming a pattern on the
photoresist; depositing a layer of metal nanoparticles (190) on the
photoresist and pattern; removing the photoresist and overlying metal
nanoparticles on the photoresist; and sintering the remaining
nanoparticles to form a metallic pattern.
