APM 90
The Accretech / TSK APM 90 Prober is a wafer prober for 6 and 8 inch wafers. The APM 90 uses a nickel chuck and has a temperature range of 25 to 150 degrees Celsius.[1][2][3][4]
What it is
How it works
General reference — not yet source-verifiedA wafer prober positions a probe assembly onto a wafer so electrical test contact can be made at selected sites on the wafer surface.
Where it fits in the process flow
General reference — not yet source-verifiedA wafer prober sits in electrical wafer test and characterization flow before full device packaging.
A wafer prober is used after wafer fabrication steps that create devices on the wafer and before downstream assembly or final package test.
Applications
General reference — not yet source-verifiedA wafer prober is used for semiconductor wafer-level testing, parameter measurement, and device evaluation.
