First, a substrate having a top surface is provided, following by forming a thermal oxide layer on the substrate. At least a part of the thermal oxidation layer is removed to form a recess in the substrate, wherein a bottom surface of the recess is lower than the top surface of the substrate. A gate oxide layer is formed in the recess, then a gate structure is formed on the gate oxide layer. The method further includes forming a source/drain region in the substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for forming high voltage transistor","description":"A method for forming a high voltage transistor is provided.
