Scrapping the Costs of an
Astandard sounds easy to meet, but semicon- ductor manufacturers know cleanroom stan- dards are anything but run-of-the-mill. The heavy price of lost product demands that
custodial partners provide service as exceptional
as the wafers you’re producing. Safeguarding profit
margins means particle control practices must be
rigorously compliant, expertly effective, and above
all, 100 percent integrated with your cleanroom
A current look at IC device manufacturing states
75 percent of yield losses happen because of contamination. When contamination is found, it’s often
smart risk management to scrap an entire batch —
easily a loss of millions of dollars. The possibility
of expensive investigations, downtime, and loss of
client and customer confidence only compound the
loss of product and productivity.
Untangling risk and cost
The pressure of production goals can also be a
source of risk. As nanometer measurements have
thinned in the semiconductor world, the prospect
of thinning profit margins has put decision-makers
up and down the supply chain to the test. If cleaning is compromised in favor of pushing production
goals, risk of contamination and risk to those same
production goals can rise.
Expert cleanroom cleaning takes that tension off
the table by protecting production with cost-effective, efficient, and most importantly results-driv-en service. In addition, proper cleaning not only
protects against the high costs of lost product, but
efficient cleaning process can affect day-to-day profitability.
A 2017 survey by Controlled Environments noted
36 percent of cleanroom cleaning tasks still reside
with cleanroom production workers themselves.1
A Gallup statistic states that people using their
strengths are six times more likely to be engaged at
work, so it’s clear that high-skill workers asked to
take on cleaning tasks may become disengaged. If
cleaning tasks are deprioritized for other responsibilities, the chance of contamination rises. An expert in
cleanroom custodial is free to focus on cleaning as a
core task and take pride in their work.
No matter how careful people are, contaminants are
introduced. Tools or equipment in the room will
generate or collect particulates that must be captured before they can migrate to sensitive surfaces.
Protecting the integrity of a cleanroom depends on
proper cleaning to reduce those contaminants.
The biggest source of contamination is people,
so training on procedure and protocol is the largest

expertly effective, and
