A well and a body region are located in the epitaxial layer. A source region is arranged in the body region, and a drain region is arranged in the well. A channel region is located in the body region between the well and the source region. A gate electrode is arranged above the channel region. In the part of the semiconductor substrate and the epitaxial layer underneath the source region and the channel region, a deep body region is present, which has a higher dopant concentration in comparison to the remainder of the semiconductor substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-voltage transistor device and production method","description":"The high-voltage transistor device has a p-type semiconductor substrate that is furnished with a p-type epitaxial layer.
