摘要： In a manufacturing method of a non-volatile memory, a substrate is provided, and strip-shaped isolation structures are formed in the substrate. A first memory array including memory cell columns is formed on the substrate. Each memory cell column includes memory cells connected in series with one another, a source/drain region disposed in the substrate outside the memory cells, select transistors disposed between the source/drain region and the memory cells, control gate lines extending across the memory cell columns and in a second direction, and first select gate lines respectively connecting the select transistors in the second direction in series. First contacts are formed on the substrate at a side of the first memory array and arranged along the second direction. Each first contact connects the source/drain regions in every two adjacent active regions.

摘要： A method for manufacturing a non-volatile memory is provided. An isolation structure is formed in a trench formed in a substrate. A portion of the isolation structure is removed to form a recess. A first dielectric layer and a first conductive layer are formed sequentially on the substrate. Bar-shaped cap layers are formed on the substrate. The first conductive layer not covered by the bar-shaped cap layers is removed to form first gate structures. A second dielectric layer is formed on the sidewalls of the first gate structures. A third dielectric layer is formed on the substrate between the first gate structures. A second conductive layer is formed on the third dielectric layer. The bar-shaped cap layers and a portion of the first conductive layer are removed to form second gate structures. A doped region is formed in the substrate at two sides of each of the second gate structures.

A second dielectric layer is formed on the sidewall of the first gate structures, and a portion of the first dielectric layer is removed to expose the substrate between the first gate structures. An epitaxy layer is formed on the substrate between two first gate structures. A third dielectric layer is formed on the epitaxy layer. A second conductive layer is formed on the third dielectric layer. The first cap layer and a portion of the first conductive layer are removed to form second gate structures. Finally, a doped region is formed in the substrate at two sides of the second gate structures.
