Edwards IQ Dry Vacuum Pumps are well-suited for vacuum applications in solar cell manufacturing. Like integrated circuit and flat-panel display manufacturing, solar cell manufacturing depends on a variety of vacuum-based processes, from PECVD (plasma-enhanced chemical vapor deposition) silicon deposition to lamination of the finished module. High pumping speeds and rapid chamber cycling are essential if these processes are to meet the throughput requirements of the solar cell industry. Edwards IQDP Dry Vacuum Pumps are dependable with benefits that include very lower up front costs, reduced energy consumption and decreased maintenance requirements.
