The semiconductor industry in Bulgaria Vol. 2

is expanding... Silicon valley, brace brace brace :D

Awhile ago, precisely on August 14th 2017, I blogged on the state of the semiconductor industry in Bulgaria. The somewhat incomplete graphic diagram got surprisingly popular amongst various internet users. Thanks to their feedback I got some additional insight on the state of the industry as a whole. Now, I'd like to share an updated diagram and some extra news.

Here's what I think is a more representative diagram as of today, to the scope of my knowledge.

Updated family tree of of semiconductor companies in Bulgaria

We can notice some differences with Version 1: firstly, the rumours that ASIC Depot exited through a sale to Broadcom were correct, and secondly, a fresh company has popped on the horizon - Photolitics, yes, that's us. Perhaps the only sole/core/purely bulgarian fabless design house in the country at the moment, also the first one in Northern Bulgaria too. The chart omits Smartcom from the list, as I don't consider them a pure-play design house, but rather a supporting custom design firm. The same applies to the LFoundry PDK team in Bulgaria too, not really pure spec-to-product chip design. Likely the same applies to ASIC Depot, but okay digital VLSI design is often rather scattered nowadays.

As with Photolitics, we are a team of 5 (soon to be six) analog gurus working towards a specific goal and standard product. Stay tuned for more, as I will dedicate a separate news release to us.

Lastly, if you know more on the topic or if you have found some inaccuracies let me know in the comments. It's highly likely that there is some information missing there.

If you are interested there is a small MEMS company in Botevgrad AMG Technology. Some of the people in this company have produced ICs in the past in Botevgrad.

Also I want to add that Smartcom business is now acquired by GlobalFoundries.

Hi, I've commented on the first post about ASIC Depot. The diagram is still wrong: ASIC Depot was created in late 2007 as I mentioned back then and it was operational since 2.1.2008, not 2010, I don't know where you got that wrong info.
(The number of employees should be very wrong, these are only emails, it has more employes by early 2008, it started with about 10 engineers) e-smarty.html ng-what-i.html

Sorry guys, the diagram will soon be updated. There is some more news on the frontline it seems. But many thanks for your input.

Sigma Delta didn't come around in 2000. It started operations in Bulgaria back in 1992/93. Up until 2000 thee were two companies under the same roof - Sigma-Delta and Elex. The all that became Melexis.
