Adhesives

Fine patterning is possible by photolithography process. These photosensitive adhesives are suitable for Si to Si, Si to glass, and glass to glass bonding of semiconductor devices, MEMS sensors, semiconductor substrates, and support plates by selectively forming a fine patterned adhesive layer. It has low autofluorescence and low cytotoxicity, which makes it suitable for BioMEMS.
Photosensitive adhesives with high transmittance (99.9%@400nm, n=1.52@550nm) are also available.

Photosensitive Film Type TMMF NA1000 (Liquid Type TMMR NA1000PM) 

Structure Formation and Substrate Bonding Can Be Done With a Single Material

  • Negative type dry film resist (solvent development type)
