Canatu invests in Lasertec’s PELMIS EUV pellicle inspection system to strengthen quality control and metrology capabilities

Canatu Plc (CANATU, Nasdaq First North, Finland) has invested in the PELMIS EUV pellicle inspection system from Lasertec to enhance its metrology capabilities in the semiconductor industry. The system enables high-precision inspection of CNT pellicle membranes for particles down to 1 micron, reinforcing Canatu’s commitment to technological excellence and product quality.

The system is essential for verifying that Canatu’s CNT100 SEMI reactors consistently produce CNT pellicle membranes with particle levels below customer specifications, a key requirement for competing in the EUV pellicle market. PELMIS detects particles as small as 1 micron and automatically classifies whether they are on the front or back side of the membrane.

“We aspire to be the world’s leading CNT pellicle player. This investment is a key enabler for the long-term development of our CNT SEMI reactor and pellicle membrane business. It strengthens our competitiveness, elevates quality control to a new level, and helps ensure we meet the stringent quality requirements of our semiconductor customers,” said Juha Kokkonen, CEO of Canatu Plc.

The PELMIS system is scheduled for delivery to Canatu’s Vantaa factory in November 2025.
