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.

My Thoughts Run Wild All The Time and I believe I have finally found the answer. I believe I have Adult Adhd. For as long as I can remember I have always had a hard time getting things done. I always needed to work on more then one thing at a time and when it is all said and done I never accomplished anything.
This has affected every area of my life and I cannot not deal with it no more. I know more then anything I need to take control of the situation and start doing some different things. My job has been affected by this, my finances have been affected and relationships have also been affected.
It is causing me great pain inside and I know now more then anything take control today. I don’t need to wait no longer. I always say tomorrow and you know what?, tomorrow never comes. What we have to tell ourselves is don’t put off tomorrow what you can do today.

Most people know the main of symptoms linked to ADHD; inattention or distractibility; impulsivity; and hyperactivity or restlessness. But did you know that one of the primary secondary characteristics of ADHD is impatience, that is only made worse by the primary symptom of impulsiveness.
Sitting in individuals long toll road lines, waiting for hours to renew your auto registration, or misplacing an essential file can drive even one of the most level headed person to the brink of an anxiety meltdown but for ADHD adults stressful situations have a tendency to spiral out of control. And it is worth pointing out that stress driven depression isn
