ASTEL SemiSyn MIL8000 Micro & Macro Inspection Wafer Loader

Product Overview

The ASTEL SemiSyn MIL8000 combines automatic wafer loading and unloading for microscope inspection with integrated macro inspection of wafer front and back surfaces. Adjustable LED frontside illumination and a contactless Bernoulli backside unit support multiple inspection tasks within a single handling workflow.

Microscope integration: ASTEL wafer loaders are designed for integration with selected semiconductor inspection microscopes from Evident / Olympus, Leica Microsystems, Nikon and ZEISS. Auckland Scientific works with ASTEL to confirm the appropriate configuration for each application and microscope model.

Key Features & Benefits

Wafer Sizes, Materials and Thickness Compatibility

The MIL8000 handles 4″, 5″, 6″ and 8″ wafers (100, 125, 150 and 200 mm), with two wafer sizes supported on one machine. Its automatic size detection allows the unit to adapt handling configuration without hardware modification.

Manufacturer-listed materials: silicon (Si), silicon carbide (SiC), gallium arsenide (GaAs), germanium (Ge), lithium niobate (LiNbO₃), sapphire (Al₂O₃), glass and other semiconductor substrates. The standard thickness range is 150–1,000 µm; other thicknesses may be assessed on request. Suitability depends on wafer geometry, surface condition, cassette and end-effector configuration.

Special thin-wafer handling: ASTEL states that TAIKO wafers down to 40 µm can be inspected using a special end effector. This is not a claim that the standard MIL handles every 40 µm wafer without configuration changes. Thin, bowed, warped and bonded wafer handling should be reviewed with ASTEL.

Compatible Microscope Manufacturers

ASTEL wafer loaders can be integrated with selected semiconductor inspection microscopes from Evident / Olympus, Leica Microsystems, Nikon and ZEISS. Auckland Scientific works with ASTEL to establish the appropriate wafer handling and microscope integration for each application. The exact configuration is confirmed as part of the quotation process. Please provide the microscope model, stage arrangement and inspection requirements when enquiring.

Compatibility must be confirmed case by case; it does not mean every microscope from these manufacturers is supported.

Frontside Macro, Backside Macro and Micro Inspection

S.A.F.E. Wafer Handling

Safe: laser cassette mapping, cross-slot detection, wafer protrusion alarm and fault monitoring (electrical, vacuum and air), combined with carbon-fibre wafer end effectors. Affordable: robust component design and compact integration intended to support lower overall operating burden. Flexible: all-wafer, selected, random and statistical inspection modes plus choice of inspection type per wafer or carrier. Easy: guided autorecipe, recipe management and touchscreen operation with automatic wafer size recognition.

Manufacturer-stated throughput is up to 200 wafers/hour, depending on configuration and inspection workflow. The published footprint is 650 × 650 mm (W × D), and the manufacturer describes an ISO Class 4 cleanroom environment, CE marking and SEMI compliance. Confirm current documentary and equipment configuration details when quoting.
