High voltage MOSFET devices and methods of making the devices
A SiC MOSFET device having low specific on resistance is described. The device has N+, P-well and JFET regions extended in one direction (Y-direction) and P+ and source contacts extended in an orthogonal direction (X-direction). The polysilicon gate of the device covers the JFET region and is terminated over the P-well region to minimize electric field at the polysilicon gate edge. In use, current flows vertically from the drain contact at the bottom of the structure into the JFET region and then laterally in the X direction through the accumulation region and through the MOSFET channels into the adjacent N+ region. The current flowing out of the channel then flows along the N+ region in the Y-direction and is collected by the source contacts and the final metal. Methods of making the device are also described.

Methods and systems for ultra-high quality gated hybrid devices and sensors
High electron mobility leads to better device performance and today is achieved by fabricating “gated devices” within a high-mobility two-dimensional electron gas (2DEG. However, the fabrication techniques used to form these devices lead to rapid degradation of the 2DEG quality which then can limits the mobility of the electronic devices. Accordingly, it would be beneficial to provide a process/technique which circumvents this processing and 2DEG layer damage. By exploiting a flip-chip methodology such damaging processing steps are separated to a second die/wafer which is then coupled to the 2DEG wafer. Extensions of the technique with two or more different semiconductor materials or material systems may be employed in conjunction with one or more electronic circuits to provide 2DEG enabled circuits in 2D and/or 3D stacked configurations. Further semiconductor materials providing EG elements may incorporate one or more of 2DEG, 1DEG, and “zero” DEG structures.
