[Ads-l] antedating "Silicon Valley"

[Bill Mullins]

OED has 25 May 1970 in the form of an advertisement in the Palo Alto Times.

The same ad appears earlier in the same paper, on 2 Feb 1970, p. 8 col. 7.

"HLS, Incorporated helps production people in Silicon Valley diffuse the exactly-right-amount of dopants into their substrates."
