鼎龙科技：公司光敏性聚酰亚胺单体是否最终应用到光刻胶领域 并未掌握具体的信息

Core Viewpoint - Dinglong Technology (603004) is currently not involved in the field of photoresist materials, focusing instead on the production of dyeing agents, specialty engineering material monomers, and agricultural protection materials [1] Group 1: Company Overview - The company primarily produces dyeing agents, specialty engineering material monomers, and agricultural protection materials [1] - Within specialty engineering material monomers, the company is actively cultivating photosensitive polyimide (PSPI) monomers, which have not yet been industrialized [1] Group 2: Product Development - Photosensitive polyimide (PSPI) monomers are core raw materials for synthesizing photosensitive polyimide materials [1] - The application fields of PSPI monomers include high-end manufacturing areas such as semiconductors, flexible displays, and micro-electromechanical systems [1] - The company does not have specific information on whether its produced PSPI monomers will ultimately be applied in the photoresist field, as this depends on disclosures from downstream and end manufacturers [1]
