New NMOS (N-type Metal Oxide Semiconductor) epitaxial deposition process is critical to faster transistors in next-generation mobile processor chips
Applied Materials has newly developed a NMOS transistor application technology on AppliedCenturaRPEpi system equipment, and continues to maintain its decade-long leadership in epitaxial technology. The development of this application technology is in line with the industry's trend to extend epitaxial deposition from PMOS (P-type Metal Oxide Semiconductor) to NMOS (N-type Metal Oxide Semiconductor) transistors at the 20-nm node, pushing chip makers to create faster terminals. To provide next-generation mobile computing capabilities.
NMOS epitaxy increases transistor speed by half a device node without increasing power consumption in the off state
“The epitaxy is an essential part of high-performance transistors, and the speed increase is equivalent to scaling half a device node.†Steve Ghanayem, vice president of transistor and metallization products of Silicon Systems Division of Applied Materials, said, “In addition to the traditional PMOS epitaxy, through the implementation of NMOS With our epitaxy process, we can help foundry customers further enhance transistor performance for next-generation devices."
Since the 90 nm termination node, strain selective epitaxial films with immediate doping performance have improved the mobility of the PMOS transistors, reduced the resistance, and increased the transistor speed. Selective epitaxy in NMOS transistors has a similar boost effect and can enhance overall chip performance. By applying this technology to both types of transistors, Applied Materials has promoted the industry to meet the demands of faster and more computing power for ever-increasing multi-functional mobile products. This increase in performance helps customers achieve more advanced features such as enhanced multitasking and higher quality graphics and image processing capabilities.
CenturaRPEpi system equipment is a leader in the PMOS epitaxial application field that has been proven in production. With the introduction of this new technology today, the scope of application of this system has now covered the selective deposition of thin films in designated areas of NMOS transistors. Applied Materials' market-leading proprietary epitaxial technology enables accurate atomic doping of high-quality strain films during deposition. Strict manufacturing process control results in excellent film properties, uniformity and very low defect rates. These characteristics solve many performance problems, including the problem of the resistivity of the critical charge layer.
Central to the market leadership of the Centura RPEpi system equipment is its integrated cryogenic pre-clean Siconi technology. Integrating the pre-cleaning and epitaxial processes on the same vacuum platform eliminates queuing time and reduces interface contamination by more than an order of magnitude compared to stand-alone stand-alone systems, creating a pure silicon surface for defect-free epitaxial crystal growth.
