How

  • Process description: Microcontact printing (μCP, mCP) of alkanethiols on gold
  • Purpose: A process is described for transferring a pattern from a silicon master via an elastomeric stamp onto a solid substrate.
  • Major advantages: In comparison to standard photolithography, microcontact printing is a low-cost,large-area, high-resolution patterning process.
  • Process: Casting PDMS (silicone) precursor (elastomer base and curing agent) onto a structured template in a Petri dish. Curing (hardening) by heat (60°C, 12-24 h).
  • Application: Microfluidic devices - Photonic crystals
