Mattson Technology, Inc. (NASDAQ: MTSN), a leading supplier of advanced process equipment used to manufacture semiconductors, today announced that it has shipped the Alpine® etch system to a leading foundry customer in Asia.

The company noted that the system shipped under an evaluation agreement and that it will be used for advanced wafer level packaging applications. The shipment marks the Alpine system's second major placement in the packaging arena, where the cost-of-ownership and ion control provide key differentiation against other etch tools available in the market.

Vice President and General Manager of Mattson Technology's Plasma Products Group, Rene George, noted, "We are extremely pleased with the evaluation selection and shipment of the Alpine etch system to this long standing customer of Mattson. Advancements in wafer level packaging continue to put demands on our customers that require enabling solutions while maintaining the lowest possible cost. The Alpine technology was chosen based on its unique ability to independently control ion energy and ion density while maintaining a very low energy level in the process chamber, resulting in enhanced process performance. Combined with our high-productivity platform, the Alpine truly offers differentiated etch capabilities at low cost-of-ownership in wafer level packaging applications. We look forward to working closely with the customer as their trusted solution provider and to fully meet their advanced packaging requirements."
