VertaCure Specs (200/300mm)
Process Management Software (option)
The YES-VertaCure automated, high temperature cure series of ovens is designed
for today’s most advanced MEMS and semiconductor process applications.
Whether it’s for proper curing of polyimide in Wafer-level Packaging (WLP)/ Redistribution Layers (RDL) applications or annealing copper in an advanced semiconductor
device, the YES-VertaCure helps achieve total environmental control to increase
yields and extend device performance.
The system incorporates the laminar flow technology of the YES-PB series.
It accommodates 200 and 300mm wafers with one or two load ports and a wafer
handling robot inside an integrated Class 1 mini-environment. Up to 50 wafers are
loaded into a stainless steel cassette-type rack on the oven chamber door and,
when loading is complete, lifted up into the vacuum chamber.
Chamber Exhaust Condensate Trap
Solvent vapor that evaporates from wafer films during the cure process condenses as soon as the process gas cools. If condensation is not controlled, condensable process effluents can plug vacuum lines, affect control valve operation and degrade the performance of vacuum pumps. YES-VertaCure Series tools use a coalescing condensate trap assembly to control the accumulation and disposal of solvent condensates. (Actual specifications of drawing may vary.)
Unique Cooling Package YES Oven Cooling Airflow
The YES-VertaCure Series cooling package allows for faster chamber cooling times as well as temperature uniformity control throughout the process. Adjustable air mixing ratio for chamber cooling adapts the tool for best performance over a broad range of operating temperatures. The design allows the process engineer total control of ramp down rates within the tool's specifications.
Exhaust Diffuser Assembly (optional)
The YES-VertaCure Series Exhaust Diffuser Assembly, when supplied with facilities cooling water, reduces facilities air-conditioning requirements by lowering the temperature of the chamber cooling air exhaust. In most cases, additional facilities ventilation is not needed. The airflow in the Exhaust Diffuser Assembly is modulated with temperature control feedback.
