Pre-Aligners- Wafer Aligner Field Proven In HVM Operations

PRE ALIGNERS- WAFER ALIGNER FIELD PROVEN IN HVM OPERATIONS

ABOUT US Kensington’s Pre Aligners have a long history of operation in semiconductor wafer fabrication. Several configurations of wafer aligners are available that support wafer sizes from 50 mm to 300 mm. The pre aligner technology is available in stand alone units as well as integrated directly into robots. The alignment technology is used for opaque as well as transparent materials and the wafer aligner supports substrates that are not round. Pre Aligners are used across the semiconductor equipment spectrum: Metrology Systems; Deposition Systems; Etch Systems; Reticle Process Systems; Thermal Processing Systems .

PRE-ALIGNERS Both integrated and external pre-aligners use transmissive sensors located within the prealigner to sense the wafer’s edge and accurately measure location and orientation during a single rotation. They accurately detect any combination of SEMI standard wafer alignment features.

EXTERNAL Our external pre-aligner is designed to mount inside the front end of the tool. It provides high throughput, up to 450 wafers per hour, while maintaining cleanliness, accuracy, and reliability. It also allows our edge grip and transmissive sensor equipped robots to perform an automated one-step self teach.

EXTERNAL SMALL WAFER Our external small wafer prealigner is designed to mount inside the front end of the tool. It provides high throughput, up to 450 wafers per hour, while maintaining cleanliness, accuracy, and reliability.

INTEGRATED The integrated pre-aligner is designed to mount on the shoulder of the robot, minimizing the footprint of the robot and pre-aligner system and maximizing cleanliness, accuracy, and reliability.
