The KLA-Tencor is a surface analysis instrument for detecting, couting and sizing of particles, i.e. light point defects. A broad range of particles size from 0.15 µm to greater than 3 µm can be measured on a polished silicon surface with or without or epitaxial layers. The particle contamination in thin films like nitride, oxide and polymer or resist layers can also be inspected.
The system will remove small surface roughness, so it will not count as particle contaminations.
 
The system is mainly being used for quality control of the PECVDs and LPCVD nitride furnaces in the cleanroom.
 
Users will have to contact the responsible persons (the Thin Film group), if they want to make some particle measurements.

EXPIRED. The KLA-Tencor Surfscan 6420 has has been removed from the cleanroom in April 2023. It has been replaced with the Particle Scanner Takano that can be used instead.

KLA-Tencor Surfscan 6420

The KLA-Tencor Surfscan (at the place in California where it was refurbished).

The KLA-Tencor is a surface analysis instrument for detecting, couting and sizing of particles, i.e. light point defects. A broad range of particles size from 0.15 µm to greater than 3 µm can be measured on a polished silicon surface with or without or epitaxial layers. The particle contamination in thin films like nitride, oxide and polymer or resist layers can also be inspected. The system will remove small surface roughness, so it will not count as particle contaminations.

The system is mainly being used for quality control of the PECVDs and LPCVD nitride furnaces in the cleanroom.

Users will have to contact the responsible persons (the Thin Film group), if they want to make some particle measurements.
