The man behind 99% chips: semiconductor legend Chih-Tang Sah’s ashes leave US for China

Remembering Chih-Tang Sah: The Semiconductor Pioneer Whose Ashes Journey to China

Chih-Tang Sah, a towering figure in the world of semiconductors, passed away on October 5, 2023, at the remarkable age of 95. Often hailed as the father of modern semiconductor technology, Sah’s groundbreaking work has profoundly influenced the electronics industry, paving the way for the ubiquitous chips found in countless devices today. Recently, his ashes were transported from the United States back to China, marking a poignant moment in the narrative of semiconductor innovation.

Early Life and Education

Born in 1928 in Shanghai, China, Chih-Tang Sah exhibited a keen interest in science and engineering from a young age. He began his academic journey at National Taiwan University before making his way to the United States for further studies. In 1954, he earned his Ph.D. in electrical engineering from the University of California, Berkeley, a milestone that set the stage for his future contributions to the semiconductor field.

Career Highlights

Sah’s career spanned several decades, during which he achieved remarkable advancements in semiconductor physics and engineering. Some notable highlights include:

• 1950s: He embarked on his research journey at Bell Labs, where he played a vital role in the development of the transistor, a cornerstone of modern electronics.
• 1970s: Sah co-authored the influential book “Semiconductor Device Physics and Design,” which became a key reference for professionals in the industry.
• 1980s: He was instrumental in establishing the semiconductor research program at the University of California, Santa Barbara, nurturing the next generation of engineers and scientists.
• 1990s: His contributions earned him the prestigious IEEE Medal of Honor, cementing his status as a leader in semiconductor research.

The Impact of His Work

Sah’s innovations were pivotal in the development of integrated circuits, which are now integral to nearly all electronic devices. His work has been credited with fueling the expansion of the global technology sector, which relies heavily on semiconductor components. Industry estimates suggest that semiconductors are present in 99% of chips used in modern electronics, highlighting Sah’s monumental influence on the field.

Ashes Returned to China

Following his passing, Sah’s family chose to return his ashes to China, a nation that has emerged as a significant player in the semiconductor industry.
