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.
After a successful pilot program in October 2009, Cancer Treatment Centers of America (CTCA) is introducing an innovative approach to cancer treatment this July at each of its four hospitals in suburban Chicago, Philadelphia, Tulsa and suburban Phoenix. Called “Patient Empowered CareSM,” this advancement in the patient treatment delivery process offers patients an average of between two and three hours with a dedicated team of specialized oncology physicians and clinicians.

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. Their main concerns are that their elected representatives are ignoring the will of the people, government is becoming too big & powerful, and spending way too much while catering to special interest groups at the expense of the average, law-abiding, tax paying American citizen.

How to adopt a baby - Ebook
The laws and policies which regulate who are actually able to adopt a child will vary from state to state, as well as from agency to agency. But there are certain requirements that almost all adoption agencies will be looking at when they talk to those people who would like to adopt a baby.
What is important to know, however, is that, although the provisions required by laws in each state can not be either changed or ignored. But there are very few, if any, requirements or rules which are not inflexible.
However, if you do find yourself during the adoption process having problems with a particular rule or guideline, then it might be advisable if you can see if that particular one can be waived.
You may be surprised that there are certain exceptions where this can occur, if the circumstances are right, or the right people have asked for it to be waived.
Although you may think that you have the right to adopt, this is simply just not the case. No one in today’s society has the absolute right to adopt a child, and can only do so after they have met certain criteria that both the adoption agencies and the government place.
It is therefore important that any prospective people wishing to adopt a baby should carry out as much research as possible on the subject. Learn everything about the rules, regulations and guidelines that can be imposed upon prospective adoptive parents by the various adoption agencies.
In this book, we will be taking you through the basics of what is required in order for a couple or single person to become an adoptive parent.
