Perpendicular MRAM

Polar Kerr System - MicroSense, LLC (MicroSense, LLC)

The Polar Kerr System for MRAM utilizes the polar Magneto-Optical Kerr Effect (MOKE) to characterize the magnetic properties of multi-layer wafers used in the development and manufacturing of perpendicular MRAM. Utilizing a non-contact full-wafer measurement technique, the system creates a map of the magnetic properties of entire wafers up to 300 mm. The system is available in a manual loading or fully-automated configuration for use in R&D and/or production.
