The commercial battle for next-generation power semiconductors is evolving. IGBTs, SiC and other technologies are geared for the niche-oriented markets at 1,700 volts and higher. But what is the best technology for the larger 600- and 1,200-volt markets? both super-junction MOSFETs and IGBTs are ramping up on 300mm wafers, making them less expensive than GaN and SiC. In comparison, SiC MOSFETs are ramping up on 100mm wafers, while GaN-on-silicon is running on 150mm substrates. This report analyzes and forecasts the traditional power semiconductor market as well as next generation devices. Market shares of vendors by type are presented.
Microcontrollers (MCUs) used in Smart Cities, Smart Homes, Smart Industry, Smart Health, and Smart Transport (a subset of the Internet of Things (IoT)), represented just 10% of the overall MCU market in 2014. But in 2020, $10 billion in MCUs, representing 40% of the total market, will be used in these applications.
A number of technical and operational trends within the semiconductor manufacturing industry are strengthening the need for more effective advanced equipment solutions. These trends include: Development of Smaller Semiconductor Features. The development of smaller features, now as small as 20nm in production and 10nm in R&D, enables semiconductor manufacturers to produce larger numbers of circuits per wafer and to achieve higher circuit performance. Transition to 3D device structures. Foundries are adopting 3D FinFET transistors starting at 14/16 nm technology nodes to get improved performance and use less power in 1x technology nodes. Memory makers will move to 3D NAND and vertical structures for next generation NAND technology. Transition to 3D Integration Technology. Three-dimensional (3D) integration of active devices, directly connecting multiple IC chips, offers many benefits, including power efficiency, performance enhancements, significant product miniaturization, and cost reduction.
