概要（Overview）

The Aleris 8510 extends the Aleris Family’s film thickness measurements, composition, and stress measurement capability to advanced high k metal gate (HKMG) and ultra-thin decoupled plasma nitridation (DPN) process layers. Utilizing enhanced 150nm Broadband Spectroscopic Ellipsometry technology, the Aleris 8510 film thickness measurement system provides engineers with the film metrology data required for development and inline monitoring of DPN layers and all HKMG layers – from gate through poly, including Hf and N dose and film thickness measurements.
