Applications:
- Wafer inspection - Wafer presenters are used to hold and rotate wafers during inspection, allowing for automated and consistent macro analysis of wafer surfaces and features. Commonly seen in raw wafer production, post-epitaxial inspection, glass wafer haze, scratch, macro defect inspection, and lot process integrity inspections in Photolithography (photoresist) and Probe/Test areas (inking).
- Scratch reduction - Scratches on wafers can occur during handling and can result in defects and yield loss. Wafer presenters are designed to lift the wafer up from its cassette, allowing operators to access and handle the wafer without having to physically go between the wafers inside the cassette. This eliminates the need for operators to manually manipulate the wafer and reduces the risk of damage or contamination.
The WHS-P4 150 mm (6") is a manual single-wafer presenter designed to improve wafer handling and inspection while minimizing the risk of damage or contamination. Available in four sizes—76 mm (3”), 100 mm (4”), 150 mm (6”), and 200 mm (8”)—this precision tool lifts a single wafer from its cassette and presents it to the operator for easy removal or macro inspection. The WHS-P4 eliminates the need for manual wafer manipulation inside the cassette, significantly reducing the risk of scratching neighboring wafers.
Constructed with antistatic materials and designed to meet strict ISO 4 (FS209E Class 10) cleanroom standards, the WHS-P4 ensures optimal protection for your wafers. Operators can use the selector to lift any of the 25 wafers in a cassette, making it an ideal tool for wafer inspection, sorting, and processing tasks. The precision antistatic lift blade allows for secure wafer handling without physical contact on the sensitive wafer surface.
The WHS-P4 offers a cost-effective, low-maintenance solution for wafer handling, making it a versatile and essential tool in semiconductor manufacturing environments. Designed to prevent wafer scratches and defects, it provides a reliable method for improving yield and reducing handling-related damage.
Manufactured in an ISO9001 certified facility and CE certified, the WHS-P4 offers a high-performance, durable solution for cleanroom wafer handling and inspection processes.
