How TCAD Can Optimize Power Electronics<\/h1>\n

The power electronics (PE) market is growing rapidly, driven by the accelerating demand of EV and HEV vehicles. Power devices lend themselves to design and manufacturing innovations at the transistor-level to improve device performance and reduce development and production costs. Silicon-carbide (SiC), gallium-nitride (GaN), and other wide bandgap materials have started to replace silicon in high-voltage power devices. Anyone designing and\/or manufacturing silicon, SiC, or GaN technologies for the power device market, should use TCAD simulations as part of their R&D efforts, to understand their devices in greater detail and improve their key Figures of Merit. Silvaco TCAD is a market leader in simulation for power devices and its products have been used by foundries and fabless semiconductor companies, worldwide, for over 25 years.<\/p>\n

TCAD modeling of power technologies allows device engineers to make virtual changes in operating conditions, the device technology i.e. planar versus trench-based structure, or in semiconductor technology such as doping and layer thicknesses. This exploration builds qualitative then quantitative understanding of devices. Iterative simulation then allows engineers to optimize device performance and operating area.<\/p>\n

With optimized devices, engineers can produce better semiconductor products and reduce the time to reach volume production, by decreasing the number of prototype wafers that need to be manufactured and characterized. Another benefit for fabless product engineers, is the ability to suggest improvements in the manufacturing process to their chosen foundry to improve yield and performance.<\/p>\n
