SIPOL series

T-NIL resist (Tg = 63 °C) with a 10% content of covalently bonded Silicon acting as an etch mask in a bilayer approach for the realization of very high aspect ratio patterns after subsequent dry etch processes

Unique Features

Material deposition on top of underlayer UL1 using spin-coating technique

  • High oxygen plasma resistance due to a Si content of 10 %
  • Good stamp release characteristics give rise to a low defectivity rate

Applications

  • Fabrication of micro/nano-scale patterns with high aspect ratios >> 3
  • Patterned sapphire substrates (PSS) for fabrication of high brightness LEDs
  • Micro/nanopillars for nanofluidic devices, e.g. DNA electrophoresis
  • Fabrication of photonic crystals
