Plasma for High-Throughput Wafer and Panel-Level Packaging
StratoSPHERE
Product Description
The StratoSPHERE™ is a high-throughput plasma treatment system for processing up to 300 mm (12 in.) semiconductor wafers. The patented plasma chamber design provides exceptional etch uniformity, process repeatability, cycle-time performance, and minimal cost of ownership. Its three-axis symmetrical chamber ensures uniform treatment of all wafer areas, and tight control over process parameters ensures highly repeatable results.
The StratoSPHERE offers industry-leading throughput and reliability for semiconductor manufacturing applications, designed to last and provide cutting-edge capabilities continuing a time-honoured tradition.
