policy TEMIC TELEFUNKEN microelectronic GmbH Meet present future national international statutory requirements. Regularly continuously improve performance products, processes, distribution operating systems with respect their impact health safety employees public, well their impact environment. particular concern control eliminate releases those substances into atmosphere which known ozone depleting substances ODSs). Montreal Protocol 1987) London Amendments 1990) intend severely restrict ODSs forbid their within next years. Various national international initiatives pressing earlier these substances. TEMIC TELEFUNKEN microelectronic GmbH semiconductor division been able policy continuous improvements eliminate ODSs listed following documents. Annex list transitional substances Montreal Protocol London Amendments respectively Class ozone depleting substances Clean Amendments 1990 Environmental Protection Agency EPA) Council Decision 88/540/EEC 91/690/EEC Annex transitional substances respectively. TEMIC certify that semiconductors manufactured with ozone depleting substances contain such substances.
