I decided to post it, as I'm getting this rumor from few sources. Here it is, even though there is no official confirmation from Magnachip:
The rumor is that Magnachip is shutting down all its US facilities - Pasadena, San Jose, Phoenix and Seattle offices. Another message says that Magnachip has decided to abandon image sensor business, as for a long time it's unable to get a significant market share and margin. Yet another message says it's a long due decision as image sensor business has quarter after quarter failed to reach its business targets.
Over the years Magnachip assembled a great team in the US. It's a pity, if they really decided to disband it.
