This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wu Dexin rather than just read about it. In short: Wu Dexin (20 December 1936 – 23 March 2026) was a Chinese scientist who specialised in semiconductor and integrated circuit. She was an academician of the Chinese Academy of Sciences.

Key takeaways

Wu Dexin belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wu Dexin to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wu Dexin from memory before moving on to harder problems.

Reference excerpt

Wu Dexin (20 December 1936 – 23 March 2026) was a Chinese scientist who specialised in semiconductor and integrated circuit. She was an academician of the Chinese Academy of Sciences.

Early life and career Wu was born in Laoting County, Hebei on 20 December 1936. After graduating from the Department of Radio Electronic Engineering, Tsinghua University in 1961, she was despatched to the Institute of Semiconductors, Chinese Academy of Sciences. She joined the Chinese Communist Party in January 1979. In 1986, she was transferred to CAS's Microelectronics Center (now Institute of Microelectronics) and appointed deputy director. In 1991, she was promoted to become director, a position she held until 1997. In 1992, she was employed by the State Science and Technology Commission (now Ministry of Science and Technology) as the chief scientist of the project "deep submicron structure devices and mesoscopic physics". She was a delegate and member of the 9th Standing Committee of the National People's Congress.

Personal life and death Wu was married to Wang Wei, who is also an academician of the Chinese Academy of Sciences. She died on 23 March 2026, at the age of 89.

Honors and awards 1991 Chinese Academy of Sciences (CAS) 1999 State Science and Technology Progress Award (Second Class) for the invention of a full set of 0.8-micron CMOS technology 2004 Science and Technology Progress Award of the Ho Leung Ho Lee Foundation

Worked examples

Example 1 — a first encounter with Wu Dexin

Start with the simplest possible case. Write down what Wu Dexin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wu Dexin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wu Dexin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wu Dexin

In research: Wu Dexin appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wu Dexin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wu Dexin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 2026 deaths, 20th-century Chinese engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Wu Dexin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
