GaN power semiconductor devices are expected to contribute to the realization of small, low-loss power electronics equipment. In particular, MOS-type GaN devices are promising candidates for next-generation power devices that can achieve normally-o­ff operation by themselves in addition to high-speed switching. The Toshiba Group has developed a process technology for MOS-type GaN devices that makes it possible to selectively control the crystallization of an AlN film on the recessed gate structure.

A trend toward the replacement of conventional mechanical relays with photorelays, which provide several advantages including smaller size, higher speed switching, longer lifetime, and lower power consumption, has recently been progressing in line with the introduction of photorelays offering more sophisticated and more efficient functions. We have developed new photorelay products that achieve smaller size and higher rated on-state current by utilizing its proprietary chip stacking technologies to attach PDA and LED chips to a MOSFET chip, in addition to a package structure that dissipates the heat of parts more efficiently.

SiC MOSFETs are a key type of power device for power supply units because of the superior performance of SiC materials. However, improvement of the reliability of SiC MOSFETs is hindered by issues associated with low carrier conductivity as a result of increased crystal defects. We have developed a new device structure for 1.2 kV-class SiC MOSFETs that can improve reliability by means of an embedded SBD located in parallel to each pn diode so as to prevent current flowing through the diode.
