This design of a unique non contact chuck, was a part of a much larger scale design and engineering project of a wet processing machine for the semiconductor industry.
The client requested Vertex to design, engineer and produce a scalable new chuck that can hold the wafer from the bottom end and at the same time process the same side which the wafer is held from. We had strict instructions not to have any contact with the top side of the wafer, due to sensitive semiconductor design on that side, therefore the name “Non Contact Chuck”.
This unique design had to overcome and avoid collision of the wafer’s holding fingers with the process module while scanning the wafer above it. This resulted in holding fingers behaving like Millipede legs.
Challenges in this design were enormous.
The chuck had to spin 360 degrees, travel on the Z axis, pressurize the top side of the wafer with air to prevent any liquid from getting to the top side, as well as, pneumatically control and actuate each finger at the right time.
Great project to work on, great challenge and great results.
Permeable or not, this is in the case of glass, in fact the question. Light shines through, this is what most people think, however, this is not quite true. Low iron glass is aimed to protect cells, but it is supposed to also let more light energy shine on the modules than normal window glass. On the other hand, modern three-or four-glazed windows let light through, but form an energy-saving temperature barrier. This way in the winter the cold stays outside and the heat inside. In the summer modern windows can automatically darken and prevent the room from heating up - energy for air conditioning is therefore saved. Glass has a lot of potential, a fact the visitors to the trade fairs glasstec and solarpeq in Düsseldorf, will have the chance to convince themselves of.
This year, Americans are planning to give back 226 million unused vacation days causing nearly 50 million of us to become vacation deprived. And, while some cite financial worries as the main contributing factor for their “no vacation” philosophies, many Americans blame “lack of planning” as the reason they find it hard to get away. Regardless of the excuse, Monograms – the all-in-one packaged vacation travel company and member of the award-winning Globus family of brands – is helping travelers make going now not only possible, but also easy.

Work intensity among European workers is still high, and it has not increased over the past five years, according to the first findings of the 5th European Working Conditions Survey, out today.
The survey also found that for most workers (67%), the pace of work is set by direct demands from people and working at high speeds remains high. The extent to which workers can make their own decisions about how they do their job has not improved, leaving a large number of workers ill-equipped to deal with work’s demands. European workers also remain as exposed to physical hazards, however, as they did 20 years ago.

A new survey finds a record number of Americans have lost confidence in their ability to afford retirement.
The 2011 Retirement Confidence Survey, released today by the nonpartisan Employee Benefit Research Institute (EBRI) in Washington, and co-sponsored by the Principal Financial Group®, found more than a quarter of workers (27 percent)—the most ever in the two decades of the survey—now say they are “not at all confident” about having enough money to live comfortably in retirement.

It\\\'s that time of year when you may find yourself feeling that dreaded tingle on you lip that you know will eventually turn into a cold sore. Although cold sores can appear on your lip year round due to cold weather, sun exposure, stress, sickness, injury to the mouth or lack of sleep, outbreaks are most prevalent in the winter time. A new, informative and entertaining website, www.MedicineNotMyth.com helps you identify the right treatments that can help you prevent or shorten an outbreak and understand and avoid cold sore triggers.
During flu season, when fever, aches, and chills hit, it is easy to forget one’s manners. A recent survey of more than 1,000 Americans found that nearly two-thirds (64%) of those who had influenza in the past three years admit to being “That Guy,” who despite experiencing flu symptoms, continues to go about his/her daily activities.
As part of its “Are You That Guy?” influenza education campaign, the National Foundation for Infectious Diseases (NFID) is partnering with the Emily Post Institute to remind Americans to do the responsible thing during flu season and practice behavior that will help limit the spread of influenza, a highly contagious virus. The campaign also reminds Americans to see a doctor quickly if flu strikes. The campaign offers flu etiquette tips for managing common situations where the flu virus might be shared from one person to another, such as shaking hands during a business meeting, over a family dinner, or when faced with a fellow airplane traveler who is showing signs of flu.

Together with comedienne Heather McDonald, Kotex Natural Balance, from Kimberly-Clark Corporation, is asking women to stand up and share their thoughts about what’s real and what’s not so real about the claims, innovations and storylines they see in today’s feminine care advertisements. Starting May 7, McDonald will star in a new web video series on the Kotex Natural Balance Facebook page (http://www.facebook.com/kotex) and YouTube channel (http://www.youtube.com/kotexvideos) that calls out the jargon in the category (what does nano-breeze maxi pad technology even mean?) and invites women to join in the conversation.
Women can upload their videos and comments on the Kotex Natural Balance Facebook page to let McDonald and Kotex Natural Balance know what’s real and what’s not. Their submissions will help inspire five more videos starring McDonald and influence material for a live Stand Up For What’s Real comedy tour that will visit major cities later this year. McDonald will perform live at select stops.

The interesting part can be found inside! Actually, this is not entirely true anymore, because packaging has reached a high-tech level for some time now. Now it can even speak. But apart from that the wrapping-industry has been developing in many directions: packaging has to be ecological, well legible, act as advertising space and of course, if nothing else, also be nice-looking. In any case, the trade fair interpack in Düsseldorf is the place to be when it comes to packaging.
