The gate is disposed on a substrate, wherein the gate includes a control gate on the substrate and a floating gate having a tip between the substrate and the control gate. The erase gate is disposed beside the gate, wherein the tip points toward the erase gate. The present invention also provides a flash cell forming process including the following steps. A gate is formed on a substrate, wherein the gate includes a floating gate on the substrate. An implantation process is performed on a side part of the floating gate, thereby forming a first doped region in the side part. At least a part of the first doped region is oxidized, thereby forming a floating gate having a tip."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flash cell and forming process thereof","description":"A flash cell includes a gate and an erase gate.
