About Epson Semiconductor

Text SizeSmallLarge

Epson thinks goof quality product comes from the attention to the earth's environment and produdct safety. We have been trying to harmonize with the grobal environment.

We achieved CFC-free manufacturing for the first time in the world. After that, according to our original environment managment system, we have been developing and manufacturing environmentally conscious products. and fulfiled our social responsibility to use resources effectively and prevent environment pollution.

Semiconductor Operations' Business Environmental Policy

  1. We build the sustainable environment management system, to reduce the loads to the global environment,This system is updated every year.
  2. We establish environmental objectives and targets, continuously reduse environmental impacts:
    • (1)Create and provide earth-friendly products.
    • (2)Transform all processes to reduce environmental loads.
      • a. Efficiently and effectively utilize natural resources and energy.
      • b. Reduce usage of materials that result in the global warming.
      • c. Suitably control chemical substances.
      • d. Purchase "Shift to green purchaing" materials.
      • e. Reduce, recycle, and reuse wastes.
      • f. Strengthen the plant & office management to enviromental risks.
    • (3)Collect and recycle used products.

Earth-friendly product information [Green purchasing, RoHS , Lead-free]

Banned chemical substance management system

We build the banned chemical substance management system based on green perchasing, purchasing the materials which pays attention to the environment from the vendors who pays attention to the environment.

Using materials that have 2 step approval

STEP1:Approving green vendor

We approve vendors who perform environmental activities and will continue to keep environmental commitment with us.

  • Are they environmental conscious?
  • Do they keep the commitment that they would not use banned chemical substances?
  • Do they control wastes properly?

STEP2:Approve raw materials

We confirm the report of chemical substances in raw materials that green vendors supply to us. We would approve these materials after knowing they are not harmful.

  • What sort of chemical substances are there and how much do these contain in a material?
  • Would you report the analysis data for chemical substances in a material?
  • Can you replace materials if contain banned chemical substances?

  • Not using banned chemical substances
  • Recycling wastes
  • Reducing emission of substances that impact global warming
  • Keeping on saving energy

* We ask our vendors to cooperate green purchase activity.

Chemical substance control status

Placing of chemical substances control is one of major environmental activities,Epson has been positively working on them . In particular, Epson has originally decided banned chemical substances not to be contained. PBBs and PBDEs, two of the six substances targeted by the EU's RoHS Directive, as prohibited substances.

Response to the EU's RoHS Directive

In FY1999, Epson commenced an initiative seeking to completely eliminate lead solder, a substance that had been pointed to as a possible environmental pollutant. In addition, to respond to the EU's RoHS Directive, the Seiko Epson Group in August 2003 began initiatives to eliminate the six substances targeted in the directive (lead, mercury, cadmium, hexavalent chromium, PBBs (polybrominated biphenyls) and PBDEs (polybrominated diphenyl ethers) from all electric/electronic products it manufactured or sold; these efforts have since reached completion.

Non-use of ozone-depleting substances (ODSs)

Epson does not use ozone-depleting substances in its manufacturing processes. In 1988 Epson declared that it would eliminate chlorofluorocarbons (CFCs), a goal that it reached company-wide in 1992. Furthermore, Epson had completely eliminated three chlorinated organic solvents (trichloroethylene, methylene chloride and tetrachloroethylene) by 1999.

*Epson does not use the ozone-depleting substances listed below in its manufacturing processes.

  1. Substances listed in Montreal Protocol Annexes A, B, E and C-II
    • (1) A Group I CFC-11, 12, 113, 114, 115
    • (2) A Group II Halon-1211, 1301, 2402
    • (3) B Group I CFC-13, 111, 112, 211, 212, 213, 214, 215, 216, 217
    • (4) B Group II Carbon tetrachloride
    • (5) B Group III 1,1,1-trichloroethane
    • (6) C Group II Halon substitutes (HBFCs)
    • (7) C Group III Chlorobromomethane
    • (8) E Group I Methyl bromide
  2. Substitute fluorocarbons (Montreal Protocol Annex C-I)
    HCFC-21, 22, 31, 121, 122, 123, 124, 131, 132, 133, 141, 141b, 142, 142b, 151, 221, 222, 223, 224, 225, 225ca, 225cb, 226, 231, 232, 233, 234, 235, 241, 242, 243, 244, 251, 252, 253, 261, 262, 271

Abolished PFOS (perfluorooctanesulfonic acid and its salt)

The PFOS (*1) was newly selected as the abolition/restriction target on the POPRC (Persistent Organic Pollutants Review Committee (*3)) of POPs treaty (*2), and it was specified as the Class I Specified Chemical Substances by the Act on Evaluation of Chemical Substances and Regulation of Their Manufacture, etc. (*4) in Japan (in April 2010).

Although the materials for semiconductor manufacturing applications are currently exempt from the regulations, we switched to using alternatives in our semiconductor manufacturing process at the end of September 2009 (our subcontractors manufacturing process at the end of June 2010), and have totally abolished the use of materials that contain the PFOS.

  • *1: PFOS: Perfluorooctanesulfonic acid and its salt
  • *2: POPs treaty: Stockholm Convention on Persistent Organic Pollutants (POPs)
  • *3: POPRC: Persistent Organic Pollutants Review Committee, a subordinate organ of the Conference of the Parties Convention on POPs treaty
  • *4: Act on Evaluation of Chemical Substances and Regulation of Their Manufacture, etc.: The Japanese law concerning the regulation of examination and manufacturing of chemicals
Abolished PFOA (Perfluorooctanic acid)

The PFOA*1 is promoted reduction based on "2010/2015 PFOA Stewardship program(PFOA voluntary reduction program)" in U.S.A. from 2006, and it is added in EU REACH*2 SVHC*3 on June 2013, etc., restriction is increasing by regulation. We switched to using alternatives in our semiconductor manufacturing process at the end of December 2013, and have totally abolished the use of materials that contain the PFOA.

  • *1 PFOA: Perfluorooctanic acid
  • *2 EU REACH: REACH(Registration, Evaluation, Authorisation and Restriction of Chemicals) is a regulation of the European Union.
  • *3 SVHC: The Substance of Very High Concern material list of matches which European Chemical Agency (ECHA) publics.(Base on REACH regulation article 59.)
