Properties

CYCLOTENE* advanced electronics resins from The Dow Chemical Company are high-purity polymer solutions that have been developed for microelectronics applications. The resins are derived from B-staged bisbenzocyclobutene-based (BCB) monomers and are formulated as high-solids, low-viscosity solutions.

Notable properties of the resins include:

Low dielectric constant
Low loss at high frequency
Low moisture absorption
Low cure temperature
High degree of planarization
Low level of ionics
High optical clarity
Good thermal stability
Excellent chemical resistance
Good compatibility with various metallization systems
Less than 5% shrinkage during cure
