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.

I bought this Drill Hole Saw for drilling holes in some very hard porcelain tile. They worked exactly as needed. I chucked the 1″ bit inside a drill press, constructed a little dam with modeling clay across the hole to hold a small amount of water and ran the bit at a slower speed. It cut an attractive hole fairly quickly. I can’t communicate to their long-term sturdiness, although following cutting a dozen=plus holes the bit was nonetheless executing well. Overall, I was extremely happy with the price/performance ratio – nicely worth the money.

Bill Gates, co-chair of the Bill & Melinda Gates Foundation, called on government leaders to increase their investments in vaccines and to hold themselves accountable for extending the benefits of vaccines to every child.
In a keynote address at the 64th World Health Assembly, an annual gathering of health ministers and global health leaders, Gates laid out his vision for the impact that broadening access to vaccines can have on the world. “Strong immunization systems will put an end to polio and help us reach all children with five to six new vaccines,” Gates said. “We can save four million lives by 2015, and 10 million lives by 2020.”

The pace of economic growth has slowed significantly since the start of 2011 and the slowdown is expected to continue into the start of 2012, according to a survey of CEOs of small-to-medium-sized businesses. The Vistage CEO Confidence Index was 92.9 in the Q2 2011 survey, substantially below the 105.2 posted in Q1, and erasing all the gains recorded since 93.7 was registered in Q1 2010. Though declines were present in every major survey component, the largest losses were in evaluations of the overall economy. Rather than expecting a renewed economic downturn, the majority of CEOs anticipated a stagnating economy: growth too slow to support robust gains in employment or investment, and resulting in lower revenue and profit levels than previously forecast. Half of all firms put planned investments on hold due to the slowdown in economic growth.
