US chipmaker plans new factory in China

GlobalFoundries will open a new factory to make cheap wireless chips in Chengdu, China, next year.

The chipmaker, once part of microprocessor designer AMD, also plans to expand production at existing fabrication plants in the U.S., Germany, and Singapore, it said Friday. It makes chips for AMD, IBM, Qualcomm, and Mediatek, among others.

Beginning next year, the new fab in China, a joint venture with the municipality of Chengdu, will produce chips on 300-millimeter wafers using standard manufacturing techniques, the company said.

Sometime in 2019, it will switch to a different manufacturing process, FD-SOI (fully depleted silicon on insulator), which GlobalFoundries calls 22FDX. That process is particularly suitable for the low-cost manufacture of the radio-frequency chips used in smartphones, cars, and the internet of things, the company said.

GlobalFoundries already uses 22FDX at its Fab 1 plant in Dresden, Germany, where it plans to increase capacity by 40 percent over the next three years.

Engineers in Dresden are already working on 12FDX, the successor to 22FDX, so-called because it will produce chips with a 12-nanometer feature size rather than the 22 nm of the existing process. Smaller features typically result in smaller chips with lower power consumption, or higher performance for the same consumption, although the use of more advanced production technologies can increase costs.

GlobalFoundries wants to use 12FDX to manufacture chips for the next generation of mobile phone networks, 5G.

In Singapore, the company will speed up lines using older chip technologies, upping production of 40 nm chips by 35 percent. It will also boost output of 180 nm chips on the older 200-mm wafers that were common before 300 mm became the norm.

GlobalFoundries was keen to emphasize that is investing in the U.S., too. It has plowed US$13 billion into its business there over the last eight years, creating 9,000 jobs at four locations around the country, it said Monday.

Since the election of U.S. President Donald Trump last November, U.S. businesses have found it expedient to promote their investment in U.S. jobs.

Just this week, Intel dusted off a six-year-old pledge to build a new factory in Arizona following a meeting between Trump and Intel CEO Brian Krzanich.

GlobalFoundries is not done investing in the U.S. yet. Early next year, it will increase production of 14 nm FinFET chips by 20 percent at its Fab 8 plant in New York, it said. FinFET (fin field-effect transistor) chips have a three-dimensional structure particularly suited to microprocessors. The company is also developing more advanced manufacturing techniques in New York and expects to begin making chips using a 7 nm process there by the middle of next year.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
