Size does matter – we think 50 µm is large – at least if it comes to LEDs. We are enthusiastic about GaN. We have a passion for precision. We love LEDs – the smaller the better.

QubeDot is founded in 2019 after more than seven years of preparation to take the technology of GaN-processing to the required level. Now we are ready – are you?

We are your partner for the processing of GaN

We love µLEDs.

Our team of 10 limit­pushers drive the future now.

Team Meet the leaders

founded in 2019, our company is led by two long-time friends

Jan Gülink

Jan is the technological backbone and his outstanding fascination for gallium nitride can inspire even people who think of completely different things.

Jan masters the processing steps to produce the µLEDs in his sleep and he certainly does not tire so quickly of developing further exciting technologies for µLEDs.

Jan’s entire career is characterized by semiconductor technology, based on a degree in electrical engineering.

Heiko Brüning

Heiko is a passionate developer and visionary who knows how to make use of latest technologies and converting these to create usable products and place them where they bring the most progress for the customer.

After his mechanical engineering studies and his doctorate in optical technologies, he spent several years in industry before starting QubeDot
