VertaCure
YES-VertaCure is a production-proven automated vacuum cure system, equipped with 5-zone uniform temperature control and laminar gas flow. This system provides excellent film performance, much higher throughput and lower CoO than atmospheric curing, and delivers superior mechanical, thermal and electrical properties for a large variety of polymers for wafer-level packaging (WLP) applications. YES-VertaCure also provides superior wafer-to-wafer (WtW) and die-to-wafer (DtW) bonding anneal.

Automated Vacuum Cure Systems

YES pioneered the use of vacuum curing, and has continued to perfect and patent the many innovations required to provide YES customers with superior film performance at twice the speed and half the cost of ownership of conventional cure technology. The VertaCure is the result of the company’s decades of experience, and large semiconductor manufacturers depend upon it for high reliability, cost-effective production.

VertaCure is a fully automated vacuum curing system that provides complete removal of residual solvents, uniform temperature distribution, complete imidization, and precise management of heating and cooling rates. Benefits include no outgassing after cure, better thermal, mechanical and electrical properties, and excellent particle performance.

The VertaCure system is available with one or two modules, for processing 50 or 100 wafers in a single run. It accommodates wafer sizes of 300mm and 200mm, and offers 200mm/300mm bridge processing capability.

Applications include advanced semiconductor packaging, wafer-to-wafer bonding, thick epoxy or PID devoiding cure, and hybrid interconnector bonding anneal.

Unparalleled Innovation

Production-proven Excellence

Utilizing YES’s patented vacuum cure process, the VertaCure offers shorter cure time, excellent temperature uniformity and high uptime for high volume manufacturing (HVM).

Chamber Exhaust Condensate Trap

Protect vacuum lines, valves, and vacuum pump performance from the accumulation of solvent condensates during the cure process. Easily dispose of the condensates.

Laminar Flow Technology

The VertaCure ensures laminar flow of gas (parallel to the wafers) to eliminate gas turbulence, resulting in excellent temperature uniformity and industry-leading particle performance.
