Endura 5500 PVD Bridge Architecture and Throughput
The Endura 5500 PVD bridge architecture is designed around a balanced cluster framework that connects several process modules through a common load lock and robot interface. This layout minimizes idle time and maximizes wafer throughput by allowing one module to perform deposition while another handles load lock operations or maintenance.
By distributing functions across dedicated chambers, the bridge reduces cross-contamination risks and supports multiple film stacks on the same tool. Advanced process control and gas delivery systems ensure uniform thickness and consistent stoichiometry across batches, even at high precursor flow rates.
Key Architectural Advantages
