Apparatus and method for fabricating semiconductor devices and substrates

摘要

An apparatus and method for fabricating semiconductor devices may increase reliability of the semiconductor devices by decreasing generation of particles and enhancing operation efficiency by decreasing the number of cleanings. The apparatus may include a chamber having a cover plate, susceptors for securely placing semiconductor substrates within the chamber, shower heads located on the cover plate to supply reaction gases into the chamber, and a curtain gas line connected to the cover plate to supply heated curtain gases between the shower heads.
