Latest Patents

One of Lee's latest patents focuses on the definition of an anti-fuse cell for programmable gate array applications. This patent describes a method for fabricating an anti-fuse cell using an undoped polysilicon film as a mask in defining the anti-fuse window. The process begins with providing a layer of silicon oxide over the surface of a semiconductor substrate. A first undoped polysilicon layer is then deposited over the silicon oxide layer. This layer is covered with a photoresist layer that is patterned to form a mask. The first undoped polysilicon layer and a portion of the silicon oxide layer are etched away where they are not covered by the mask to create a cell opening. After removing the mask and the remaining silicon oxide within the cell opening, an insulating layer is deposited over the surface of the first undoped polysilicon layer and within the cell opening. A second polysilicon layer is then deposited over the insulating layer and doped. Finally, the second polysilicon layer is patterned to form an anti-fuse cell, and gate electrodes along with source and drain regions are formed, completing the fabrication of the integrated circuit device.
