The end of the year means we once again have an excuse to showcase some of our favorite SEM images taken at SMS as part of ongoing research initiatives (and a few taken just for fun). We hope you enjoy this short tour through the tiny world that our work encompasses.
Inverted Features
Last year we showed that we were able to invert our features through post processing steps. This year we began attempting to create the inverted features directly in the mold. The result is the ability to make a first gen replica with inward facing features, as shown in these images from different attempts.

High Aspect Ratios
This year we also experimented with increasing the aspect ratios of features, as demonstrated with these pillars
SubMicron Features
Throughout the years, we’ve refined our ability to pattern submicron features, increasing the aspect ratios and improving the feature registration. A 400nm pattern (top) and 700nm pattern (bottom) from our dust mitigation efforts are shown below.
Complex Diamond Dies
We have also developed new diamond-die patterns, including micropyramids with different feature pitches on each facet, which give rise to eye-catching optical effects.
Solar Films
A few SEMs from our work on creating light trapping films for solar panels.
