SC26 Magnetic Field Cancelling System
Spicer SC26 Overview
Semiconductor manufacturing facilities have their own unique DC magnetic fields created by the wafer transport robots operating within 300 mm wafer fabs. These magnetic fields, usually in the 9 kHz range, degrade the imaging and analytical performance of electron beam imaging and analysis tools also located in the fab. The SC26 cancels the magnetic fields that are unique to semiconductor manufacturing facilities with overhead wafer transport robots.
Description
The SC26 system is a wide bandwidth system that can cancel magnetic fields from DC up to 10 kHz. This results in an ambient magnetic field that is compatible with optimal electron beam tool operation in wafer fabs. The SC26 uses low inductance field cancelling cables to achieve its wide bandwidth. A VEC engineer installs these cables in the electron beam tool enclosure. There are inputs for two 200 kHz AC field sensors, allowing signal mixing to optimize the electron beam tool performance. Field cancelling can be extended down to DC by adding a “Sensor SC24/DC+AC” and a sensor combiner for each input channel used. The SC26 cannot be used with larger cables in a “room” installation.
