Abstract: A non-volatile memory disposed on a substrate includes active regions, a memory array, and contacts. The active regions defined by isolation structures disposed in the substrate are extended in a first direction. The memory array is disposed on the substrate and includes memory cell columns, control gate lines and select gate lines. Each of the memory cell columns includes memory cells connected to one another in series and a source/drain region disposed in the substrate outside the memory cells. The contacts are disposed on the substrate at a side of the memory array and arranged along a second direction. The second direction crosses over the first direction. Each of the contacts extends across the isolation structures and connects the source/drain regions in the substrate at every two of the adjacent active regions.

Abstract: A method of manufacturing a non-volatile memory is provided. In the method, a first dielectric layer, a first conductive layer, and a first cap layer are formed sequentially on a substrate. The first cap layer and the first conductive layer are patterned to form first 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.

Abstract: The invention provides a dynamic random access memory (DRAM) with an electrostatic discharge (ESD) region. The upper portion of the ESD plug is metal, and the lower portion of the ESD plug is polysilicon. This structure may improve the mechanical strength of the ESD region and enhance thermal conductivity from electrostatic discharging. In addition, the contact area between the ESD plugs and the substrate can be reduced without increasing aspect ratio of the ESD plugs. The described structure is completed by a low critical dimension controlled patterned photoresist, such that the processes and equipments are substantially maintained without changing by a wide margin.
