Hummink Unveils Bird Screen-Repair Module, Tested in South Korea

At the Semicon Europa trade show in Munich, running from November 10 to 13, French deep tech firm Hummink will unveil Bird, its industrial module, for the first time. The company likens itself to a semiconductor “microsurgeon.” The show runs concurrently with electronica, and the presentation was announced by L'Usine Nouvelle.

A screen can lose a pixel because an electrode is severed, an interconnect is open, or a control circuit fails. According to Hummink, these localized defects can be repaired using high-precision additive printing tools, meaning tools that add material rather than removing it. The cost of the problem is high: according to TechFundingNews, up to 30% of OLED screen production, organic light-emitting diode displays, is scrapped each year, representing roughly €16 billion in losses.

Hummink's technology is called high-precision capillary printing, known by the company's acronym HPCAP. Its first system, the NAZCA demonstrator, is already installed in leading research laboratories, according to TechFundingNews. It is used to locate and repair defects at the sub-micron scale, meaning below one micrometer. Bird is presented as a module intended for industry.

Hummink was founded in 2020 as a spin-off of École normale supérieure – PSL and CNRS, in Paris. According to its profile on the Semicon website, it has representatives in South Korea, the United States, Taiwan, Japan and Europe. Its €15 million funding round, announced on November 17, 2025, was co-led by KBC Focus Fund, Cap Horn and Bpifrance. The funds are intended to develop the industrial module and prepare its integration into semiconductor manufacturing.

Screen and chip makers are the first to be affected, since each repaired defect saves a part from being scrapped. No deployment timeline or pricing has been disclosed. What is dated is the November 2026 trade show and the integration goal financed by the fundraising.

The available extracts from L'Usine Nouvelle do not detail the tests conducted in South Korea, which the headline mentions. Their duration and results are not specified. What Bird will deliver in production remains to be proven.
