IC Substrate

IC substrates: critical interfaces between the semiconductor chip and the printed circuit board

Fabricators of these IC substrates require the capability to deliver interconnect densities far beyond that of the typical printed circuit board fabricator. To successfully build these complex designs, manufacturers require a partner with proven solutions and specialty chemical expertise in high density designs. We are that solutions provider.

Our Systek™ line of IC substrate chemicals provide the solutions for the most technically challenging high-density designs. No other company has the breadth of chemistries and technical expertise to meet the most stringent requirements while achieving higher productivity at economical costs.
