Two new products from semi equipment manufacturer Altatech: one for ultra-thin film deposition, and one for searching out nano-defects. Altatech is a division of Soitec, best known in the advanced substrates community for its leadership in SOI wafers. This part of the company, however, develops highly efficient, cost-effective inspection and chemical vapor deposition (CVD) technologies used for R&D and manufacturing of semiconductors, LEDs, MEMS and photovoltaic devices.
The company’s newest inspection system, the Orion Lightspeed™, is capable of pinpointing the size and location of nano-scale defects inside compound semiconductor materials and transparent substrates (see press release here). The new system helps to ensure the quality control of high-value engineered substrates used in several fast growing markets including high-brightness LEDs, power semiconductors and 3D ICs. Inspection is based on Altatech’s patented synchronous Doppler detection™ technology, which determines the exact size and position of defects by making direct physical measurements with resolution below 100 nm. This provides true defect sizing, as opposed to other types of inspection equipment on the market that make indirect measurements using diffracted light to calculate approximate defect sizes. It handles 200mm or 300mm substrates, with throughput of 85 and 80 wafers per hour, respectively. Beta systems have already been installed at customers’ facilities and are demonstrating excellent performance. Shipments of production units are scheduled to begin in April 2015.
The new AltaCVD 3D Memory Cell™ is the latest member of Altatech’s AltaCVD line, designed to deposit ultra-thin semiconductor films that enable the manufacturing of high-density, low-power memory ICs used throughout mobile electronics (see press release here). The new system performs atomic-layer deposition 10 times faster than conventional atomic-layer deposition (ALD) systems, helping to meet global market demands for both high-volume production and cost efficiency in fabricating advanced memories. The system is currently demonstrating its unique capabilities and performance at one of Altatech’s key customers. Production units are available.
