Even more than an SEM, an STM needs a conductive sample surface that can be galvanically connected to a reference potential.

For non-metallic samples, we can achieve this again using a metal thin film deposition technique like sputtering.

For us, STM non-metallic imaging may be interesting for taking pictures of dies which are not fully conductive across their surface.
