| Cleanrooms and clean environments are
required for the manufacture of many products that have exacting contamination
control requirements to achieve defined yield and reliability targets.
Clean manufacture is required for the production of items such as
semiconductors, hard-disk drives, flat panel displays, and materials
for the pharmaceutical industry. Requirements of cleanroom/clean environments
and tooling result in low humidity levels, low surface contamination
levels, use of process-required insulators, and a lack of natural
ions in the controlled environment. These factors can contribute to
development of elevated static charge levels in close proximity to
sensitive product, presenting both contamination and electrostatic
discharge exposure. |
