Trends in the Semiconductor Industry
1940s to 50s
From the late 1940s to the 1950sThe transistor was invented in the U.S. and mass production of transistors was also established in Japan.
The demand for consumer electronics was boosted in Japan in the ecomic recovery after WWII, and transistors supported this move.
1947 - early 1950s: Invention of the transistor and the beginning of the semiconductor industry
In December 1947, the point-contact transistor was invented at AT&T Bell Telephone Laboratories (BTL), followed by the junction transistor in January 1948. In 1951, BTL made its transistor patents and technology available to the world, and the semiconductor industry rapidly developed and expanded. Japanese companies also entered the transistor business, and by 1960 Japan became the world's largest transistor manufacturer.

1953 to mid-1950s: Japanese manufacturers started production of germanium transistors
After acquiring the patents from Western Electric Co., Sony produced the first commercial transistor radio in August 1955, in the midst of "radio boom (vacuum-tube based).
"As many other Japanese manufacturers entered this race, Japan gained worldwide recognition of "the transistor radio made in Japan."
February, 1956: Establishment of Semiconductor Laboratory on the West Coast of the U.S. The birth of Silicon Valley
Shockley Semiconductor Research Laboratory was established in Mountain View by William Shockley. Following this, many semiconductor and related companies were born in this area. A monument to the "Birthplace of Silicon Valley" was erected at the site of the Shockley Research Laboratory.
1958: Invention of IC in U.S.
Jack Kilby from Texas Instruments (TI) invented the germanium solid-state circuit and acquired the patent on monolithic ICs.

1959: Japan reaches No.1 in the production of germanium transistors
With transistor radios becoming increasingly popular, Japanese manufacturers started to use their own processes and equipment in the mass production of transistors.
Japan produced 86 million transistors in 1959, supplanting the U.S. as the world’s No. 1 producer.
1959: U.S. succeeds in commercializing silicon transistors
Over several years following 1956, the U.S. expedited the development of silicon transistors, having superior thermal and frequency characteristics than germanium transistors, for use in the military, aerospace, and computer industries.
