Realtek Semiconductor was founded in 1987 in Hsinchu Science Park, Taiwan's "Silicon Valley". With the passion and perseverance of a few young engineers, Realtek Semiconductor has gone through the difficult initial stage to become a world-leading professional IC design company today. Realtek Semiconductor has overcome many difficulties, demonstrated strong ambition and outstanding competitiveness, and developed high-performance, high-quality, and high-cost IC solutions that are widely recognized and welcomed by the global market. Realtek Semiconductor has maintained steady growth since its establishment, thanks to Realtek's persistence and efforts in product/technology research and development and innovation, as well as Realtek's fine traditions.
