ABSTRACT

Semiconductor factories have always been a large consumer of electrical energy and there is an on-going introspective examination by many semiconductor companies to reduce their energy consumption as part of their global environmental policies. With the current slowdown in the semiconductor industry many semiconductor companies have also been reviewing expenses to identify opportunities for cost savings. Motorola has scrutinised its energy conservation policies in its semiconductor operations and the result has had significant progress in reducing operating expenses. Motorola’s energy policies have resulted in reoccurring annual savings of over $4,500,000. Savings have been achieved with changes in cleanroom operating conditions and an aggressive collaboration between manufacturing sites around the world. This article will present an overview of Motorola’s energy conservation policies its multi-site energy council, new cleanroom design criteria and how changes to existing factories have resulted in actual utility cost savings.
