    摘要: A combination wafer is manufactured by (i) forming a plurality of alternating dielectric and metal layers, (ii) forming a guard ring trench in the layers, (iii) forming a guard ring layer in the guard ring trench, and then repeating (i), (ii) with a slightly wider guard ring trench, and (iii). A number of layers are thus simultaneously etched and lined with a guard ring layer, but the number of layers is not so large so as to cause lithographic problems that may occur when a deep, narrow guard ring trench is formed. An upper one of the layers that are patterned is always made of silicon dioxide, which includes less carbon than lower polymer layers and allows for a carbon mask to be formed and be easily removed. The slightly wider guard ring trench each time the process is repeated overcomes lithographic alignment problems that may occur when the guard ring trenches are exactly the same size. Subsequent guard ring layers are partially formed on one another, and provide a moisture seal. The guard ring layers are formed at the same time when vias are formed that are connected to electronic elements.

    摘要: The effects of a self-erase phenomenon when accessing imprinted ferroelectric memory cells that have non-conductive electrode interfaces that reduce remnant polarization and decrease signal margin are eliminated. A self-erase control pulse asserted after an access pulse is utilized. The self-erase control pulse has a magnitude sufficient to offset a remnant charge on the non-conductive electrode interfaces after the removal of the access pulse.

    摘要: According to one aspect of the invention, a memory array and a method of constructing a memory array are provided. An insulating layer is formed on a semiconductor substrate. A first metal stack is then formed on the insulating layer. The first metal stack is etched to form first metal lines. A polymeric layer is formed over the first metal lines and the insulating layer. The polymeric layer has a surface with a plurality of roughness formations. A second metal stack is formed on the polymeric layer with an interface layer, which is thicker than the heights of the roughness formations. Then the second metal stack is etched to form second metal lines. Memory cells are formed wherever a second metal line extends over a first metal line.
