MIL8000 Wafer Inspection System and Microscope Loader
产品查询MIL8000 wafer autoloader and macro inspection station represent the most effective system to automatically load wafers on a microscope and to perform a wafer front and backside macro inspection. It is a compact unit, which makes it possible to load wafers on a microscope and perform Macro Front and Back inspections.
Features:
- Safe and reliable handling of thin wafers with high bow and warpage
- Safety features for operator and process error protection
- Carbon fiber end effectors for scratch-free handling
- Simplified cassette profile definition with auto recipe tool
- Automatic adaptation to different wafer thicknesses based on laser mapping sensor measurements
- Multiple wafer selection methods for productivity and ease of use
- Optimized control software for reduced cycle times
- Programmable inspection types at carrier or wafer level (macro front-side, macro backside, micro)
- Powerful computer control with a user-friendly touchscreen interface
- Easy recipe management for handling configuration switching
- One-click operation for streamlined workflow initiation
