SESHA 2011 Program Book - Semiconductor Safety Association

product is 12-inches wafer, and it covers an area of 54
million square meters, of which the gross Investment
reaches to 5.26 billion dollars. About 3700 employees
from Korea and China work for HSCL.Safety and Health
Committee Safety and Health committee is a communication
bridge between employee and employer, created
by Hynix and Hynix labor union together for the purpose
of promoting mutual understanding between the
labor and the capital, dissolving and improving internal
issues of environmental, health and safety related to employees,
making the optimal working environment for
employees. Specificity 1. Specialty As far as the organization
structure is concerned, Safety and Health committee
is a newborn thing. Similar organization structure
has not been found by now in other related industry. 2.
Innovation In a point of view of foreign labor unions’
operating mode, there is a sharp contradiction in terms
of interests between labor union and enterprises. But the
Hynix labor union is designed to protect and coordinate
the interests of both sides of labor and capital, satisfy
the employees and promote the enterprise development
as well. Operation Overview 1.Organization Chairman
of a committee; Chinese labor union chairman, Korean
deputy general manager Committee member; Korean
leaders from manufacturing department, technology
department, general affairs department, and personnel
labor union committee Executive:Responsible persons
from ESH department 2.Operation Mode: Practical
meeting: We collect advice and suggestions monthly
from the basic level by various means and hold the practice
meeting to take them over in the end/beginning of
a month. Solutions will be taken out and significant issues
would be submitted to periodic meeting for further
discussion.Periodic meeting:Periodic meeting is held
quarterly to debrief the results of practical meeting and
provide advice and solutions to significant issues. 3.Operation
Content: Safety: Clean room odor, PPE, toxic
gas monitoring Environment: Dorm odor, corporate
environment, sewage treatment Occupational health:
noise, psychological consult, smoking and drinking, individual
radiation dosimeter 4.Operation results Safety
and Health Committee has collected and disposed more
than 200 advice and suggestions from 2008. Our operating
environment and the safety consciousness of workers
has been greatly improved. And the sense of trust
between labor and capital has been enhanced a lot as
well. As a result, our employees put more energy into
production, makes more output and profit. In 2010, We
Hynix got the historically highest profits.

Odor is caused by one or more
volatilized chemical compounds that human being can
perceive by the sense of olfaction and can feel unpleasant
and disgusted. It is one kind of sensory pollution that
results in physical and psychological harm. Especially,
semiconductor industry have had difficulty in managing
unclear odor as air pollutants generated by many
kinds of gasesous chemical compounds and considering
reduction measures. Hynix Semiconductor Inc. judged
that odor problems will be issued by residents because
the residential areas have been created close to Cheongju
site. Therefore, our company put technical measures
to practical use for odor management generated from
semiconductor plant. In first step, the correlation between
the concentration of exit specific compounds(e.g.
HF, NH3) and the odor was considered for selecting
odor index. The complex odors in itself were selected
for the optimal management index. In second step, reduction
characterisitics by emission sources for the
practical use of odor reduction were studied. Especially,
the exhaust part of the thin film process had the
highest odor concentration based on the result derived
from the priority for the classification of the emission
odors. A wet scrubber in installed to treat the odor intensively
between the plasma scrubber to decompose
PFC gas at high temperature and the final wet scrubber.
Also, the odor removal efficiency of Hume generated
from SC-1 wastewater(Mixed of NH4OH and H2O2)
improved with building the wet scrubber (H2SO4 neutralization)
for NH3. Its process is seperated from existing
wet scrubber(NaOH neutralization) for acid. Hynix
Semiconductor Inc. was able to decrease about 70% of
complex odors in 2010 compared to 2009 with the odor
reduction technologies as state above. Odor monitoring
systems for odor quality analysis and real-time management
are being currently investigated. This research introduces
our company’s odor reduction control system
for win-win strategy between the semiconductor industries
and the nearby residents.
