INFICON Recognized with Supplier Excellence Award from ON Semiconductor

Sponsored by Businesswire

INFICON Inc., a leading supplier of vacuum instrumentation and process
control software to the semiconductor manufacturing industry, has been
recognized by ON Semiconductor as their 2018 Front End Site Supplier of
the Year. Jeffrey P. Wincel, Vice President and Chief Procurement
Officer, ON Semiconductor, presented the award to Steve Lakeman, Senior
Director of INFICON’s Intelligent Manufacturing Systems division at a
ceremony in Vietnam on April 30, 2019. This prestigious award
acknowledges the contributions the INFICON FabGuard® Process
Control System provides in meeting the quality and consistency
challenges of today’s semiconductor manufacturing.

“Our experiences working with INFICON are truly in the spirit of
win/win,” said Wincel. “They are flexible with our ever demanding and
growing needs to continuously improve. They in turn work these needs
into a cost and licensing structure that accommodates our budgets. They
are indeed a true partner to ON Semiconductor.”

As ON Semiconductor wafer fabs began to deploy the FabGuard software,
the company realized immediate results as FabGuard improved yield and
reduced wafer scrap. Since then, ON Semiconductor fabs, existing and
newly acquired, continue to deploy this level of control well beyond the
original scope. INFICON is working closely with ON Semiconductor to
develop new capabilities, including targeting the monitoring and control
of subfab and facilities equipment.

“We are extremely proud of this award from On Semiconductor and will
continue to expand our manufacturing software capabilities to provide
this great partner the tools they need to provide innovative solutions
to their customers,” said Oliver Wyrsch, President, INFICON Inc.

The proven success of FabGuard at ON Semiconductor has permeated into
their supply chain, as many of its suppliers now also use FabGuard
software to maximize their own processes.
