Description

With its unique optical design technology, the Imperia system detects and classifies yield-killing defects with the additional benefit of simultaneous state-of-the-art photoluminescence (PL) production monitoring.

Product Overview

With unique optical design technology, the Imperia system detects and classifies yield-killing defects with the additional benefit of simultaneous state-of-the-art photoluminescence (PL) production monitoring. Combining these two post-epitaxial metrology screening functions into a single high throughput system minimizes valuable fab space use and cassette handling time. This product can provide significant economic savings to the user (for example: accurately predicting MOCVD reactor yield and PM schedules).

High density spectral PL mapping
