Article Synopsis
  • A new silicon mold process using picosecond lasers offers an alternative to traditional SU-8 soft lithography for creating PDMS microchannel chips, achieving a minimum feature size of 50 μm.
  • The silicon patterns are created by cutting a 550 μm thick silicon wafer, then processed to remove debris and a protective oxide layer before being bonded to glass substrates via anodic bonding.
  • This maskless process does not require a photolithography facility, although it does need specialized laser cutting services from off-campus providers, and demonstrates potential applications like particle separation in PDMS microchannel chips.
