T sai Ming-kai is a Taiwanese technology billionaire who is the chairman of MediaTek, a leading global fabless semiconductor company. He is widely revered in his home country as the "Godfather of Taiwan's IC design industry." After a successful career at the electronics firm UMC, he spearheaded the spin-off of the company's integrated circuit (IC) design division in 1997 to create MediaTek. This move allowed the new company to focus exclusively on designing chipsets, without the massive capital costs of manufacturing.

Under his decades of leadership, Tsai built MediaTek into a global powerhouse. The company's initial success came from dominating the market for the chipsets that powered DVD players and, later, the vast market for lower-cost feature phones. He then successfully navigated the company's challenging transition into the smartphone era, becoming a major global supplier of powerful and cost-effective chipsets for Android smartphones and competing fiercely with the American giant Qualcomm. His strategic vision and technical expertise have been central to the company's enduring success.
