The method for manufacturing a semiconductor device includes defining trenches in a semiconductor substrate having active regions and isolation regions. The trenches are partially filled with a first insulation layer. An etch protection layer is formed on the surfaces of the trenches that are filled with the first insulation layer. A second insulation layer is filled in the trenches formed with the etch protection layer to form an isolation structure in the isolation regions of the semiconductor substrate. Finally, portions of the active regions of the semiconductor substrate are recessed such that the isolation structure has a height higher than the active regions of the semiconductor substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing a semiconductor device capable of preventing the decrease of the width of an active region","description":"A method for manufacturing a semiconductor device that can prevent the loss of an isolation structure and that can also stably form epi-silicon layers is described.
