The first recorded proposal for using digital electronics in computing was the 1931 paper "The Use of Thyratrons for High Speed Automatic Counting of Physical Phenomena" by [[C. E. Wynn-Williams]].<ref>{{Citation | last = Wynn-Williams | first = C. E. | author-link = C. E.

The concept of a [[field-effect transistor]] was proposed by [[Julius Edgar Lilienfeld]] in 1925. [[John Bardeen]] and [[Walter Brattain]], while working under [[William Shockley]] at [[Bell Labs]], built the first working [[transistor]], the [[point-contact transistor]], in 1947.<ref name="Lee">{{cite book |last1=Lee |first1=Thomas H. |title=The Design of CMOS Radio-Frequency Integrated Circuits |date=2003 |publisher=[[Cambridge University Press]] |isbn=9781139643771 |url=https://web.stanford.edu/class/archive/ee/ee214/ee214.1032/Handouts/HO2.pdf |access-date=16 September 2019 |archive-date=9 December 2019 |archive-url=https://web.archive.org/web/20191209032130/https://web.stanford.edu/class/archive/ee/ee214/ee214.1032/Handouts/HO2.pdf |url-status=dead }}</ref><ref name="Puers">{{cite book |last1=Puers |first1=Robert |last2=Baldi |first2=Livio |last3=Voorde |first3=Marcel Van de |last4=Nooten |first4=Sebastiaan E. van |title=Nanoelectronics: Materials, Devices, Applications, 2 Volumes |date=2017 |publisher=[[John Wiley & Sons]] |isbn=9783527340538 |page=14 |url=https://books.google.com/books?id=JOqVDgAAQBAJ&pg=PA14}}</ref> In 1953, the [[University of Manchester]] built the first [[transistorized computer]], the [[Manchester Baby]].<ref>{{Citation|last=Lavington|first=Simon|title=A History of Manchester Computers|year=1998|edition=2|publisher=The British Computer Society|___location=Swindon|pages=34–35}}</ref> However, early [[junction transistor]]s were relatively bulky devices that were difficult to mass-produce, which limited them to a number of specialised applications.<ref name="Moskowitzvijayvsr">{{cite book |last1=Moskowitz |first1=Sanford L. |title=Advanced Materials Innovation: Managing Global Technology in the 21st century |date=2016 |publisher=[[John Wiley & Sons]] |isbn=9780470508923 |pages=165–167 |url=https://books.google.com/books?id=2STRDAAAQBAJ&pg=PA165}}</ref>

In 1957, Frosch and Derick were able to manufacture the first silicon dioxide field effect transistors at Bell Labs, the first transistors in which drain and source were adjacent at the surface.<ref>{{Cite journal |last1=Frosch |first1=C.
