Longtu Photomask

Shenzhen Longtu Photomask Co., Ltd. was established in 2010. It is an independent third-party semiconductor photomask manufacturer with key technology research and development capabilities and independent intellectual property rights. The company's main business is the research and development, production, and sales of semiconductor photomasks. The company closely follows the development path of domestic specialty process semiconductors, continuously conducting technological research and product iteration. Its semiconductor photomask process node has gradually improved from 1μm to 130nm. Its products are widely used in specialty process semiconductor fields such as power semiconductors, MEMS sensors, IC packaging, and analog ICs. Terminal applications cover scenarios including new energy, photovoltaic power generation, automotive electronics, industrial control, wireless communication, IoT, and consumer electronics.
The company will follow the national semiconductor industry development strategy, focusing on the high-end semiconductor chip photomask field, continuously increasing R&D investment, and gradually achieving mass production and domestic substitution of 90nm, 65nm, and higher node photomasks. It will deeply cultivate specialty processes, break through high-end manufacturing processes, and aspire to become a domestic first-class benchmark enterprise in semiconductor photomasks.
