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.

One of our very first tracking classes. 22 degrees and very windy and cold. Hudson spent quite some time casting side to side to snack on deer poop (yuck!) but did manage to get to the glove!
iLand is more a destination than a game. When you get there navigate with the MOVE button, to move forward, backwards and side to side. To look around, use the ROTATE button, slide your finger from side to side and up to down depending what you want to see.
At the Plaza with "On the Sunny side of the street" played on the 1931 Compton pipe organ. In this video I tried to play exactly how I think a 1930s cinema organist would have done ie I didnt try and sound like another organist or follow a particular style. I simply banged out the tune!!! :-)

Lyrics :
You're better then the best
I'm lucky just to linger in your light
Cooler then the flip side of my pillow, that's right
Completely unaware
Nothing can compare to where you send me,
Lets me know that it's ok, yeah it's ok
And the moments where my good times start to fade
You make me smile like the sun
Fall out of bed, sing like bird
Dizzy in my head, spin like a record
Crazy on a Sunday night
You make me dance like a fool
Forget how to breathe
Shine like gold, buzz like a bee
Just the thought of you can drive me wild
Ohh, you make me smile
Even when you're gone
Somehow you come along
Just like a flower poking through the sidewalk crack and just like that
You steal away the rain and just like that
You make me smile like the sun
Fall out of bed, sing like bird
Dizzy in my head, spin like a record
Crazy on a Sunday night
You make me dance like a fool
Forget how to breathe
Shine like gold, buzz like a bee
Just the thought of you can drive me wild
Ohh, you make me smile
Don't know how I lived without you
Cause every time that I get around you
I see the best of me inside your eyes
You make me smile
You make me dance like a fool
Forget how to breathe
Shine like gold, buzz like a bee
Just the thought of you can drive me wild
You make me smile like the sun
Fall out of bed, sing like bird
Dizzy in my head, spin like a record
Crazy on a Sunday night
You make me dance like a fool
Forget how to breathe
Shine like gold, buzz like a bee
Just the thought of you can drive me wild
Ohh, you make me smile

Hey, Everyone! This is my new tribute to my one and only Hero: Aaron Hotchner. This clip was made because he is strong, stubborn, lonely and so sad. And he still stands in spite of what his scars say. He is a real lonely hero. He means everything what this word, hero means. In my next life I'll look for a man like him first! :)))
Oh, and I want to dedicate to Thomas Gibson too, cuz it was his 47th birthday yesterday! I know he will never watch this, but who cares!?
