Abstract
Provided is a dry-film suitable for use in forming an optical component. The dry-film includes a carrier substrate having a front surface and a back surface. A negative-working photoimageable polymeric layer is disposed over the front surface of the carrier substrate, and includes a photoactive component and units of the formula (RSiO), wherein R is a substituted or unsubstituted organic group. In each of the units, R is free of hydroxy groups. The units include units of the formula (RSiO) and (RSiO), wherein Ris a substituted or unsubstituted aliphatic group and Ris a substituted or unsubstituted aromatic group. A protective cover layer is disposed over the front surface or back surface of the carrier substrate. Also provided are methods of forming optical devices with dry-films. The invention finds particular applicability in the optoelectronics industry.
