Claim Text:
1. A method for manufacturing a low resistance polysilicon (poly) strap comprising: fabricating a structure including a programming oxide separating a first poly from a second poly, the second poly separating the programming oxide from an insulator, the first poly extending from a device region to a strap region, the first poly extending substantially parallel to a first length of the second poly, a second length of the second poly extending away from the first poly in the strap region, and a first diffusion region crossing the first poly and the second poly in the device region; etching the insulator to form a spacer, the spacer defining a masked width of the first length of the second poly; etching the second poly excluded by the spacer in the device region to a first depth to leave the masked width of the first length of the second poly and etching the second poly excluded by a mask in the strap region to leave the second length of the second poly; forming a salicide on at least the second length of the second poly; planarizing the first poly and the second poly to a second depth by substantially removing the spacer; and forming a contact with the second length of the second poly in the strap region.
