Thin-film Stress and Strain

In Situ Thin-Film Stress, Strain and Wafer Curvature

The thin-film stress and strain that occur in real-time during growth impact the thin-film performance and reliability. k-Space offers four tools to measure thin-film stress and strain all based on the kSA MOS optically based technology. The kSA MOS is used for real-time measurement in situ during processes such as MBE, sputtering, PLD, E-beam evaporation, and thermal processing. For MOCVD, the kSA ICE provides real-time in situ modular system. The kSA MOS UltraScan and kSA MOS ThermalScan are ex situ used on wafers, mirrors, glass, and more.

kSA MOS

In Situ tool for measuring real-time film stress, film strain, and wafer curvature induced by thin films or thermal processes on a substrate/wafer.

kSA ICE

MOS Module: In situ modular tool for measuring real-time film stress, film strain and wafer curvature induced by thin films or thermal processes on a substrate/wafer, ideal for MOCVD reactors with high speed or low speed rotation and limited optical access.
