Reports indicate that Samsung Electronics has officially restarted its silicon carbide (SiC) semiconductor business. The company is collaborating with material, equipment, and component suppliers to advance the construction of an 8-inch SiC production line.

Huaxi Securities noted that with the rapid growth in downstream application demand, major global manufacturers are increasing their focus on SiC. This heightened attention is leading to greater investment in SiC chip production lines, which is expected to catalyze new demand for upstream substrates and equipment.

Public information shows that TIANYU SEMI is the largest domestic and the world's third-largest self-manufacturer of SiC epitaxial wafers. In February of this year, TIANYU SEMI formally entered into a strategic cooperation agreement with South Korea's EYEQ Lab Inc., focusing on the supply and application of SiC epitaxial wafers. EYEQ Lab is a leading company in South Korea's third-generation semiconductor SiC power semiconductor sector.

It is reported that EYEQ Lab previously received investment from Patron, a Samsung subsidiary. Samsung Electronics is also actively expanding its business in the SiC power semiconductor field and has internally established a new SiC power semiconductor team.
