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.

The American Pain Foundation (APF), in partnership with professional baseball player LaTroy Hawkins, acknowledges those suffering from Postherpetic Neuralgia (PHN) today, as it recognizes the second annual PHN Awareness Day. PHN Awareness Day was created to raise awareness to the pain caused by shingles and PHN, also known as after-shingles pain. Shingles is caused by the reactivation of the same virus that causes chickenpox and can affect an individual who has had chickenpox at anytime without warning. More than 90 percent of adults in the United States have had chickenpox, placing them at risk for shingles. One in every five of the 1 million Americans who have had shingles each year may go on to develop PHN, a potentially devastating condition that disproportionately affects those over the age of 50 or with weakened immune systems.

A man sets the ringtone for his bank text message alerts to the sound of “toilet flush” every time he pays a checking fee.
