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.

Recently, aspiring country music artists, Richard and Robert Fay, also known as R&R Double Take, came to New York to record Paul Val's latest hit, The Silent Majority Is Silent No More. This song celebrates the fact that average Americans, who are usually silent, are finally exercising their First Amendment rights to voice their concerns about Government and are getting involved in the electoral process in a big way.

However, when people think of a break in, they think of someone gaining entry in to their home through breaking some glass or smashing down doors. Yet there are certain things which could actually extend an invitation to those unwanted intruders to make an attempt at getting into your home.
There are many places which are vulnerable to attack from an intruder to your home, and therefore you must set up a routine which will then provide them with less opportunities of attempting to break in. Below, we look at what are considered to be some of the weak areas in your home security routine which could help to prevent any kind of break in from occurring.
