A multitude of jigsaw patterned lateral isolation trenches are formed in a substrate of the device. The trenches are configured to isolate the laterally staggered line-in and line-out source regions from a common drain region of the plurality of semiconductor device legs. The staggered devices are also designed for staggered time and staggered heat conductivity delays and current spreading from the package input to an output of a respective pair of devices to improve current and heat conductivity from the package input to an output of a subsequent pair of devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power semiconductor device and package","description":"A power semiconductor device and package includes multiple electrically parallel semiconductor device legs designed to share source regions and share a drain region between two devices in each leg lat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10535579","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
