LINEAR PECVD APPARATUS

摘要

The present invention generally relates to a linear PECVD apparatus. The apparatus is designed to process two substrates simultaneously so that the substrates share plasma sources as well as gas sources. The apparatus has a plurality of microwave sources centrally disposed within the chamber body of the apparatus. The substrates are disposed on opposite sides of the microwave sources with the gas sources disposed between the microwave sources and the substrates. The shared microwave sources and gas sources permit multiple substrates to be processed simultaneously and reduce the processing cost per substrate.
