For decades, the semiconductor industry has maintained a strategy of delivering chips that have doubled in performance every two years through the ongoing migration to smaller process geometries. The reduced circuit dimensions yield higher performance while requiring less power, which is critical for mobile electronics devices, a market segment fueling much of the growth in the semiconductor industry. However, the inverse power-to-performance ratio is becoming harder to sustain as circuit designs move to 65 nanometer (nm) and beyond. One factor is that the physical properties of the silicon itself are presenting a major performance limitation. As such, a new company, MEARS Technologies, has been launched to re-engineer the physical properties of silicon in order to reduce gate leakage by as much as 60 percent in NMOS transistors and up to 80 percent in PMOS transistors, while maintaining drive current for a variety of deep sub-micron processes. Through this unique approach, MEARS Technologies intends to enable semiconductor companies to continue with their aggressive device roadmaps while still leveraging the semiconductor industry's existing manufacturing infrastructure.
"Silicon devices make up approximately 95 percent of the $250 billion semiconductor market. However, it is becoming increasingly clear that the limitations of bulk silicon are beginning to compromise the ability of CMOS manufacturing to deliver exponentially better performance at ever lower cost and power," said Bill McClean, president of IC Insights, a leading market analyst firm tracking the semiconductor industry. "While recently introduced options offer a viable short-term boost in performance, the industry as a whole has been searching for a breakthrough that extends the life of CMOS and lowers power dissipation -- without requiring sweeping changes in materials or huge investments in new manufacturing equipment and facilities." MST(TM) Platform Mitigates Gate Leakage MEARS Technologies is tackling the issues of chip performance and power consumption head-on with its new MST(TM) Platform. Static power dissipation, also called gate leakage, can account for as much as 70 percent of the total power budget of devices manufactured at the 65 nm process node. Using a band engineering approach, MEARS Technologies has developed its patented MST Platform to dramatically reduce gate leakage, providing a tremendous advantage for all applications that benefit from reduced power consumption. In addition, the new technology will enhance drive current, which relates directly to increased semiconductor speed. "The explosive growth of cell phones and other personal electronics devices has created conflicting demands for semiconductors with increased performance and reduced power consumption," said Robert J. Mears, founder and president of MEARS Technologies. "The ability of the industry to respond to these demands continues to depend on the electrical properties of a single material -- silicon. As chipmakers attempt to squeeze more performance out of their transistors, the fundamental properties of silicon and its native oxide have become the limiting factor. And while some approaches have been successful in addressing performance requirements, power issues continue to exist. Through a new approach to silicon engineering, we are able to alter the properties of the silicon to improve the power efficiency and speed of transistors manufactured using deep sub-micron process nodes such as 65 nm, 45 nm and beyond, while maintaining compatibility with standard CMOS manufacturing equipment that is used for the vast majority of today's semiconductors." Compatible with Today's Standard Manufacturing Processes MEARS Technologies' MST Platform is designed to be fully compatible with semiconductor manufacturers' baseline processes, whether it be bulk CMOS, strained silicon or silicon-on-insulator. The power improvements are achieved through a band engineering approach that is based on a deep understanding of the quantum mechanics of modern deep-submicron devices. In its first implementation, MST Generation 1 is a channel replacement technology incorporating a silicon laminate, or "superlattice" layer, which requires no new materials be used in the fabrication process. This "silicon-on-silicon" solution adds only a few steps to the standard CMOS manufacturing flow -- and at virtually no additional cost or impact to production yields.
