For today’s busy families, getting sick is no fun. With cough, cold and flu season here, many parents are taking precautions to help keep their children healthy. According to the Centers for Disease Control and Prevention (CDC),¹ one of the best ways to protect against getting sick is to wash hands often. To help teach families about the importance of clean hands and preventing the spread of germs, Wet Ones® Antibacterial Hand Wipes has launched the Wet Ones Healthy Hands Zone™ website, an educational resource developed by Bill Nye, renowned science educator and author of Bill Nye the Science Guy's Great Big Book of Tiny Germs.

Choosing the right tires and properly maintaining them are effective ways to enhance your vehicle’s performance and improve road safety. This week is National Tire Safety Week and leading tire manufacturer Michelin is reminding consumers of the benefits of choosing the right tires and of simple, cost-effective ways to contribute to tire safety. After all – your tires are the only part of your car in contact with the road.

Roughly 100,000 licensed skin divers are active in Germany. In Frankfurt on the river Oder three clever buffs have just devised a way to introduce the underwater world to everyone. A two-man mini-submarine enables people to submerge without a license and without getting wet. By now submersible Nemo 100 has won awards and attracted worldwide interest. At a cost of about 180,000 Euros the vehicle, produced in a small batch series only, targets a wholly new market for mini-subs: Compared to other submersibles Nemo is a real bargain.
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.
Presented here is an extensive product design and engineering effort, from the ground up of a Semiconductor Wet Processing System. This new system is capable of fully automated, cassette-to-cassette, true single-sided wet processing of 1-12\
