Asomlei Closes $5M Bridge Round to Deploy CNT-Based EUV Pellicle Membrane Production Line - Wowtale

South Korean startup Asomlei has closed a $5 million Series B bridge round and established a dedicated cleanroom production line for EUV pellicle membranes in Anyang, Gyeonggi Province. The funding ro... Read original →

Asomlei’s funding and cleanroom deployment mark a pivotal shift from lab-scale to industrial production of carbon nanotube-based EUV pellicle membranes, reshaping the photomask material supply chain. This advancement pressures upstream carbon nanotube producers and downstream EUV equipment vendors to align with new performance standards. Government-backed credit guarantees reduce R&D and production risks, but may trigger international scrutiny over technology transfers. With competitors like Samsung and LG Chem entrenched in advanced materials, Asomlei must rapidly scale quality and delivery to avoid marginalization. Over the next 12–24 months, if its product enters mainstream foundry supply chains, it could accelerate domestic material substitution and force global semiconductor material ecosystems to restructure. Success would solidify South Korea’s strategic autonomy in advanced materials.
