What Must Be Monitored for Manufacturers of Electronics Devices?

Measure or estimate these parameters annually

~

~

~

~

Annual manufacturing capacity of
each fab (m2).

Annual production in terms of
substrate surface area (m2) for
each fab, including specification of
the substrate.

Amount of each fluorinated GHG
consumed in process sub-types,
and process types; and the amount
of N2O consumed in CVD and
other N20-using processes (kg).

Annual fab-level emissions of each
fluorinated GHG, including each
input gas and each by-product gas,
used for the plasma etching/wafer
cleaning process type and each of
the process sub-types associated
with the chamber cleaning process
type, including in-situ plasma
chamber clean, remote plasma
chamber clean, and in-situ thermal
chamber clean (metric tons).

Inventory of each fluorinated

~	GHG and N2O stored in containers
at the end of the reporting year.

Acquisitions of each fluorinated

~	GHG and N2O through purchase
records or other transactions (kg).

~ Disbursements of each fluorinated
GHG and N20.

~

~

~

Disbursements under exceptional
circumstances of gases through sales
or other transactions.

Number of containers of gas returned
by the facility to gas distributors.

Full capacities of gas containers
used.

Annual emissions of N2O for each

~	N20-using process type, on a fab
basis (metric tons).

Inventory of each fluorinated GHG

~	and N2O stored in containers at the
beginning of the reporting year.

Fab-wide heel factors for each gas
and container type used.

Process sub-type-specific, and
process type-specific fluorinated
GHG apportioning factors; and
CVD-specific and other N20-using
process-specific N2O apportioning
factors.

-------
If you elect to use the stack test method:

~

For each stack system in the fab for
which testing is required, measure the
emissions of each fluorinated GHG
from the stack system by conducting
an emission test. In addition, measure
the fab-specific consumption of each
fluorinated GHG by the tools that are
vented to the stack systems tested.

~

~

Develop fab-specific emission
factors for each fluorinated GHG
input gas consumed and each
fluorinated GHG formed as a by-
product; and calculate fab-level
fluorinated GHG emissions.

Total annual emissions of fluorinated
GHGs from all of the combined
stack systems that are not tested in
the fab.

If you use fluorinated heat transfer fluids (HTFs):

Annual emissions of fluorinated
~ HTFs on a fab basis using the mass
balance approach, as applicable.

~

~

~

The density of each fluorinated HTF
used at the facility.

Inventory of each fluorinated HTF in
containers, other than equipment, at
the beginning of the reporting year.

Inventory of each fluorinated HTF in
containers, other than equipment, at
the end of the reporting year.

~

~

~

~

Acquisitions of each fluorinated
HTF, including the amounts
purchased from chemical suppliers,
equipment suppliers with or inside
equipment, and returned to the
facility after off-site recycling.

Total nameplate capacity of
equipment that uses a fluorinated
HTF and is newly installed during
the reporting year.

Total nameplate capacity of
equipment that uses a fluorinated
HTF and is removed from service
during the reporting year.

Disbursements of each fluorinated
HTF, including amounts returned to
chemical suppliers, sold with or
inside of equipment, and sent off-site
for verifiable recycling or
destruction.

If controlled emissions from the use of abatement systems are reported:

Fraction of each fluorinated GHG
used in process sub-types, or process
~ types with abatements systems; and	~

the fraction of N2O used in CVD or
other N20-using processes.

~

Fraction of each fluorinated GHG
destroyed or removed in abatement
systems for process sub-types, or
process types; Fraction of N2O used
~ in each N20-using process with

abatement systems; and the fraction
of N2O destroyed or removed in
abatement systems for CVD or other |—|
N20-using processes.

~

The total time, in minutes, that
abatement system p, connected to
process tool(s) in the fab using
input gas in process sub-type or
process type j, is not in operational
mode.

Properly measured and class average
DREs, when the EPA default DRE
factor is not used.

Uptime of each abatement system
used at the facility connected to
process tools in the fab.

The total time each abatement
system is in operational mode and
fluorinated GHGs or N2O are
flowing through the connected
process tools.

Amount of each fluorinated GHG
consumed for process sub-type, and
process type fed into each abatement
~ device used at the facility; the amount
of N2O consumed for CVD and other
N20-using processes fed into each
abatement system used at the facility.

~

The total time fluorinated GHGs or
N2O are flowing through process
tools connected to each abatement
system.
