Photomasks - Seeking Projection Perfection

Photomasks, the quartz plates that hold microchip circuit patterns, must be as close to perfect as possible. Any imperfections will be reproduced on every chip on every wafer, potentially wasting a lot of time and expensive silicon.Applied is a vital part of the mask making ecosystem. Virtually every high-end mask is made using Applied’s Tetra etch systems, a new version of which has just been released.

Is Automation Software Useful in LED Manufacturing?

In his blog, James Moyne talked about Applied Materials’ software footprint as it relates to crystalline silicon (c-Si) solar production. James highlighted a specific scenario where advanced process control plays an important role in addressing issues associated with solar cell printing. As this type of technology becomes widely adopted, the c-Si solar industry will collectively improve processes and drive the quality and conversion efficiency of the product to new highs.The LED manufacturing world has an interesting mix of semiconductor technology and c-Si manufacturing practices. This raises the question: can automation software be beneficial—and affordable—for LED production lines? The answer is YES, and I’ll begin to tell you why.

Fixing a Planar Problem

For the past several years, the industry has been transitioning to high k metal gate (HKMG) transistors in high-performance logic chips. It’s been a tough engineering challenge requiring extensive research into new materials and production processes. But today, HKMG transistors are successfully being produced in high volume manufacturing for advanced logic devices.
