LONDON Ė Analog, mixed-signal and power IC maker Telefunken Semiconductors International said it plans to expand its 200-mm wafer fab in Roseville, Calif., making it one of the largest foundry service companies in the U.S.
The first phase of expansion plan provides for a 100 percent increase in wafer processing capability to more than 220,000 wafers per year or 5.5 million mask layers per year. Telefunken did not indicate how much this doubling of manufacturing capacity would cost or how much more Telefunken is ready to spend on other phases of expansion. The first phase of expansion is expected to be completed by 3Q13. A second phase of expansion to take manufacturing to three times the present capacity is expected to complete by 4Q14.
The Roseville plant was orginally constructed by NEC before being passed to Renesas Electronics Corp. as part of Japan's restructuring of its chip manufacuting sector. Renesas sold the wafer fab to Telefunken in 2011 for approximately $50 million.
"The increased capacity is the result our recent acquisition of the state-of-the-art semiconductor equipment from factories in Japan," said Roger Lee, CEO of Telefunken Semiconductors, in a statement. "The added tools will help us to satisfy the strong demand we are forecasting from our customers. This will move Telefunken Semiconductors into one of the top spots for specialty foundries in the Western world. Growing our capacity with advanced silicon processing tools and offering a comprehensive suite of strategic foundry services at a competitive cost is an important part of our overall corporate mission," Lee added.

A few years ago, I was working on the design of a data acquisition system (DAS) that would eventually need to be tested when manufactured. It had both high-side current sensing and floating diff-amp input channels. I could either recommend to the client that some expensive equipment be bought and configured for such testing or else design and build some prototypes of a Floating Differential Source (FDS) which would cost much less. I did the latter.
As an engineer, eventually you will have to insert an equation into your written work or presentation. This can be a struggle as equation editors are not always the friendliest. However, there is good news. The equation editor in Word has improved immensely (I am using version 2010 here). In this blog we look at how to insert an equation into a Word document. As a bonus, there is information on how to insert an equation into a web page with an html code generator website.
Wait a minute. Letís see if I understand this. (Here Iím channeling you, the puzzled reader, after youíve grabbed me in the coffee break of a Filter Wizard lecture morning). The frequency of the nth harmonic of a sinusoid is n times that of the fundamental. The nth harmonic distortion is defined as the ratio of the amplitude of the nth harmonic to the amplitude of the fundamental. So the 1st harmonic distortion isÖ the ratio of the amplitude of the fundamental to the amplitude of the fundamental and thatísÖ unity. I. Do. Not. Understand.
