Figure 2: Lateral MOSFET using GaN with transitional layer material to align the lattice using Si or SiC as a substrate The common approach to accomadating the crystallographic differences is through the use of a buffer layer (Figure 3). MOSFET + GaN HEMT can achieve this. GaN FETs have inherently superior performance over traditional silicon FETs, which is enabling engineers to push the boundary in power designs and reach new levels of power density and efficiency. … Switches fabricated from semiconductors such as GaAs, SiC and GaN hold promise if hold-off voltages of several kilovolts and fast rise rates are needed.

It has in-house processes for Si and GaN and uses the technology of growing GaN as well as hetero epitaxial GaN on Si. GaN switching devices are available in two different types: enhancement mode (e-GaN) and cascoded depletion mode (d-GaN). They are available in the traditional TO-247 and TO- 220 case styles and can accept a wide range of gate -drive voltages, encompassing every other device standard (Figure 6). The superior performance of GaN versus SiC can be attributed to its lower Eon/ Eoff. However, cascode SiC JFETs can drop right in. Die MOSFET- und JFET-Technologien teilen sich auf in MOSFET (Si) mit konventioneller Planar-Technologie und Superjunction-Technologie, MOSFETs (SiC) in konventioneller Planarstruktur und JFETs (GaN) als selbstleitend und selbstsperrend. The gate loop and common source inductance are also minimized in the GaN FET power stage package to be below 200 pH. SiC vs GaN semiconductors for EV power converters: Tech Opinion.
