Low‐pressure cold welding has been used to fabricate 200 μm diameter organic light‐emitting devices (OLEDs) (see Figure). The contacts are made by transferring a metal film from a patterned, soft elastomeric stamp onto unpatterned organic and metal layers on a substrate. The process does not adversely affect the OLED performance when compared with those fabricated by shadow mask patterning.
