Taiwan Speciality Chemicals Corporation (TSCC) was established in March 2013 and settled in Changhua Coastal Industrial Park, Changhau County, with 75,000m2 (18.5 acres) of land.
TSCC aims at Specialty Electronic-Graded Gases (SEG) and Specialty Electronic-Graded Chemicals (SEC) to be professional semiconductor developed manufacturer. The main products are Disilane, Trisilane and Related silicon products.

TSCC holds unique R&D technology and patterns regarding manufacturing process which the production line is capable of co-producing Disilane(Si2H6), Trisilane(Si3H8) and by-products. We are honor to supply high-end quality products for many well-known semiconductor companies.

Chemical and Gas Professional Laboratory is a protector to ensure the quality for our customers. In addition, we have been applying for Taiwan Accreditation Foundation (TAF) Certification.

TSC has the certifications of ISO9001 and OHSAS18001. The great importance of Social and Environmental Responsibility is TSCC main purpose, especially for employees and working environment.

Diligence, pragmatism, professionalism as well as creativeness are TSCC utmost purpose. We devote to be the best partner for Semiconductor key material so as to meet TSCC version “Special gas sales over the global, Specialty chemicals widely used in the world”.
