School students visit point electronic

At this year’s career exploration day, “Girl’s Day and Boy’s Day 2026,” the young people got a behind-the-scenes look at our company.

ADF image of 4 × 1017 doped Si p–n junction sample used for biasing experiments (b–f) EBIC under different applied biases from −2 to +2 V. The bottom electrode connected to the psub side of the sample was held at 0 V (to avoid noise in the readout equipment connected at this side) while the top electrode voltage was varied. The sign convention used in this work was chosen so that the reverse bias condition of the p–n junction. refers to a negative bias voltage, i.e., the p-side is at a lower voltage than the n-side). (This figure was acquired using C STEM mode, convergence semi-angle = 23.5 mrad).

What do traffic lights, binary clocks, and smileys have in common? At this year’s career exploration day, “Girl’s Day and Boy’s Day 2026,” at point electronic GmbH, the students built and programmed them themselves.

In our software department and production area, they had the chance to get hands-on and try things out for themselves. Our visitors first learned how a scanning electron microscope works. Then they got to use the microscope themselves. Various small samples were first properly prepared and then magnified to enormous size under the microscope.

The students also got a behind-the-scenes look at our software and production departments—from writing code for a working sensor-controlled mini-traffic light to soldering mini-circuit boards themselves, such as for smileys that can change their faces at the push of a button.

In any case, yesterday created lots of wonderful memories! And we’ve gathered a few of them together in this post.

Thank you all for joining us! And thank you to our colleagues who made this exciting day happen.
