*ISO-9001 is recognized around the world as a quality standard for the semiconductor industry that spells out specific quality system requirements aimed at preventing non-conformity at all stages of a company's activity. ISO-9001 certification assures customers that the product they purchase was built to world class quality requirements.

ISO 14001 specifies requirements for an environmental management system to enable an organization to develop and implement a policy and objectives which take into account legal requirements and other requirements to which the organization subscribes, and information about significant environmental aspects. It applies to those environmental aspects that the organization identifies as those which it can control and those which it can influence. It does not itself state specific environmental performance criteria.
