With the unchanging trend of falling LED prices, chip manufacturers are constantly improving LED chip production process and technologies to lower costs. Semiconductor equipment company GT Advanced Technologies (GTAT) has developed Hydride Vapor Phase Epitaxial (HVPE) system that can replace nGaN and uGaN growth process in MOCVD. In the future, LED chip manufacturers can add HVPE systems to speed up epitaxy growth rates. Compared to adding MOCVD to expand production capacity, using HVPE system can increase production capacity and help LED chip manufacturers cut up to 25 percent of costs.
