Abstract: Some disclosed embodiments are directed to methods and systems for performing pair-wise delta compression. For example, systems obtain a set of files to be compressed into a single compressed file. The system identifies different attributes related to the set of files. For each file in the set of files, the system predicts an optimized set of candidate compression files and calculates a delta between each file in the optimized set and the target file corresponding to the optimized set. After identifying the smallest delta, the system compresses the selected pair of files associated with the smallest delta in order to generate the single compressed file for the set of files.

Abstract: A SiC-based MOSFET device and a method for manufacturing the same. Layout design of SiC-based MOSFET devices is optimized, which keeps the JFET region while introducing shielding regions extending into the JFET region, thereby retaining the current flow area of the JFET region to a great extent; each shielding region is connected to the respective well region and extends into the JFET region along a diagonal direction of the cellular structure, effectively shielding high electric field regions when the device is reverse biased, and significantly enhancing the device's reliability. The shielding regions and the well regions are simultaneously formed, requiring no additional process, avoiding increase in complexity and cost of manufacturing. This approach achieves low on-resistance and prevents a decrease in reliability caused by the electric field strength at the bottom of the gate oxide layer exceeding a critical breakdown electric field strength of the gate oxide layer.
