Silicon Glen

Silicon Glen is a nickname for the high tech sector of Scotland, the name inspired by Silicon Valley in California. It is applied to the Central Belt triangle between Dundee, Inverclyde and Edinburgh, which includes Fife, Glasgow and Stirling; although electronics facilities outside this area may also be included in the term. The term has been in use since the 1980s. It does not technically represent a glen as it covers a much wider area than just one valley.


German semiconductor company TDK-Micronas have a large site in Glenrothes

Silicon Glen had its origins in the electronics business with Ferranti establishing a plant in Edinburgh in 1943. NCR Corporation, Honeywell and Burroughs Corporation followed in the late 1940s with IBM being a very significant import when it opened a manufacturing facility in Greenock in 1953. Indeed, this was typical of much of the early days of Silicon Glen, which were dominated by electronics manufacturing for foreign companies much more than research and development or the establishment of home grown companies.

The emphasis on electronics came about due to the decline in traditional Scottish heavy industries such as shipbuilding and mining. The government development agencies saw electronics manufacturing as being a positive replacement for people made redundant through heavy industry closures and the associated training and reskilling was relatively easy to achieve.

Like the bedrock of Silicon Valley was in semiconductors, Silicon Glen also had a significant influence in semiconductor design and manufacturing starting in 1960 with Hughes Aircraft (now Raytheon) establishing its first facility outside the US in Glenrothes to manufacture germanium and silicon diodes. In 1965 Elliott Automation established a production facility in Glenrothes followed by a MOS research laboratory in 1967. This was followed in 1969 by the establishment of wafer fabs by General Instrument in Glenrothes, Motorola (now Freescale) in East Kilbride and National Semiconductor in Greenock. Signetics also opened a facility in Linlithgow in 1969. In 1970 Compugraphic[1] relocated from Aldershot to Glenrothes to provide photomask manufacturing for these companies. Other companies who developed semiconductor wafer fabrication or other manufacturing plants included SGS in Falkirk, NEC, Burr-Brown Corporation, IPS (then Seagate Technology) and Kymata (now Kaiam) in Livingston, CST in Glasgow and Micronas in Glenrothes.

There were some other notable successes such as the large Sun Microsystems plant in Linlithgow and the Digital Equipment Corporation semiconductor manufacturing plant in South Queensferry where the pioneering 64-bit Alpha 21064 and its derivatives were made. Digital also opened an office in Livingston, developing their flagship VAX/VMS operating system.

Rodime of Glenrothes pioneered the 3.5 inch hard disk drive in 1983 and spent subsequent years defending its patents against (and collecting royalties from) Seagate, Quantum, IBM and others.

The manufacturing sector grew to such an extent that at its peak it produced approximately 30% of Europe's PCs, 80% of its workstations, 65% of its ATMs and a significant percentage of its integrated circuits.[2]


Rockstar North, the creators and developers of popular video game series Grand Theft Auto, are based in Edinburgh

The heavy dependency on electronics manufacturing hit Silicon Glen hard after the collapse of the hi-tech economy in 2000. Viasystems, National Semiconductor (now Texas Instruments), Motorola and Chunghwa all laid off substantial numbers of employees or closed factories completely. The effects of the Viasystems closure are still felt in the Scottish Borders today. Digital sold their Alpha facility to Motorola who eventually closed it down. Motorola also closed their factory in Bathgate and the substantial NEC plant in Livingston was also closed. In 2009 Sun ceased manufacturing at its Linlithgow plant[3] and, after successive years of downsizing, NCR ended all manufacturing in Dundee.

However, there are many promising signs as well as a recognition that diversification away from electronics and manufacturing produces a more balanced and stronger economy. There is also more of an interest in encouraging home grown talent.

To diversify away from electronics and manufacturing, the development agencies now see global services as being a potential area of growth, but there is also substantial interest in the software development industry, including Rockstar North, developers of the market leading Grand Theft Auto series. There is also a dynamic and fast growing electronics design and development industry, based around links between the very strong universities and indigenous companies and projects like the Alba Campus. The software sector has also notably attracted to set up a software development centre in Edinburgh, the first such centre outside the US. There remains a significant presence of global players like National Semiconductor, IBM, Shin Etsu Handotai Europe Ltd and Freescale. The move from a primarily manufacturing dominated region to a wealth creation one has been successful as demonstrated in a report from UBS Wealth Management in 2006 showing Scotland with more venture backed companies per capita than any other UK region.

In addition to the indigenous companies, Silicon Glen continues to have quite a significant semiconductor design community of inward investment companies including Atmel, Freescale, Texas Instruments, Micrel, Analog Devices, Allegro MicroSystems, Micro Linear, Micronas and ST Microelectronics.

Semefab, the former General Instrument semiconductor foundry, has been funded as the UK's Primary Centre for the development of microelectromechanical systems (MEMS) and nanotechnology.[4]

Scotland had 1,000 companies in electronics employing 25,000 people in 2004, this number has been in decline since 2000 when 48,000 people were employed in the industry in Scotland.[5] However, by 2016 the Silicon Glen has begun to boom once again, with new digital start ups - such as Skyscanner - choosing Scotland for headquarters or offices. In 2015 a new Scottish digital currency was proposed called the ScotPound. Although the Scottish government hasn't yet begun work on this digital currency, a private project called ScotCoin, inspired by the idea, has emerged.[6] SCOTEX is a proposed Scottish Stock Exchange, started in 2016, seeking to provide listing for many of these tech sector companies.[7]

18% of the UK's space industry is based in Scotland, and Glasgow builds more satellites than any other city in Europe. Two locations in Scotland - Prestwick Airport and the A' Mhòine peninsula - are up for consideration for the UK's first spaceport.[8][9][10]

The Open Source Awards (formerly the Scottish Open Source Awards) have been run from Scotland since 2007. It was initially a subset of the Scottish Software Awards.
