A charge storage layer is formed over the substrate including over the gate stack. A first sidewall spacer of conductive material is formed along a first sidewall of the gate stack extending past a top of the select gate. A second sidewall spacer of dielectric material is formed along the first sidewall on the first sidewall spacer. A portion of the first sidewall spacer is silicided using the second sidewall spacer as a mask whereby silicide does not extend to the charge storage layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and structures for a split gate memory cell structure","description":"A method of forming a split gate memory cell structure using a substrate includes forming a gate stack comprising a select gate and a dielectric portion overlying the select gate.
