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.

Six of 13 small cars recently evaluated by the Insurance Institute for Highway Safety earn the TOP SAFETY PICK award, and none earn a poor rating in any of 4 tests. This is a turnaround from a few years ago when small cars struggled to earn top safety ratings. The new tests include hybrids and gasoline-only models that are among the most fuel-efficient vehicles available in the U.S. market.
The ratings are based on performance in front, side, rollover, and rear impact evaluations. Cars that earn the top rating of good in each test and have available electronic stability control (ESC) qualify for TOP SAFETY PICK. Winners are the 2012 Ford Focus and Honda Civic, along with the 2011 Hyundai Elantra, Lexus CT 200h hybrid, Nissan Juke, and Toyota Prius hybrid. The Civic, CT 200h, Elantra, Focus, and Prius have at least one version with a government fuel economy rating of at least 40 miles per gallon on the highway. The Dodge Caliber, Honda CR-Z and Insight hybrids, Nissan Sentra and Versa, Scion xD, and Suzuki SX4 also were rated but didn’t earn TOP SAFETY PICK.
Join P&G and the Children’s Safe Drinking Water Program (CSDW) to provide clean drinking water to children in need.
GIVE HEALTH partners with the non-profit P&G Children’s Safe Drinking Water Program (CSDW) to provide PUR packets in developing countries. These packets, developed by P&G and the U.S. Centers for Disease Control, use some of the same ingredients as municipal water systems to remove pollutants from contaminated water. Since 2004, CSDW has provided more than 3 billion liters of water to children in need in over 60 countries.

When it comes to their health, nearly 90 percent of Americans lack the literacy skills to understand basic medical information and instruction. Low literacy has been linked to poor health outcomes such as higher rates of hospitalization and less frequent use of preventive services. A few quick minutes with a physician is not sufficient for most of us to understand a complex or chronic medical condition and how we can manage it. But new research indicates that video storytelling can be an effective way to educate people about health conditions - and watching others share their health stories can empower people to take control of their own health.
