    摘要: As disclosed herein, a structure and method is provided for forming an integrated circuit including a reduced programming voltage antifuse on a semiconductor substrate. The method includes doping a portion of a semiconductor substrate with nitrogen and a charge carrier dopant source, and forming a thin dielectric over the doped portion of the semiconductor substrate, wherein the thin dielectric is subject to breakdown upon application of a breakdown voltage. The method further includes forming a first conductor separated from the semiconductor substrate by the thin dielectric, and forming a second conductor conductively coupled to the doped portion of the semiconductor substrate.

    摘要: Forming a vertical MOS transistor or making another three-dimensional integrated circuit structure in a silicon wafer exposes planes having at least two different crystallographic orientations. Growing oxide on different crystal planes is inherently at different growth rates because the inter-atomic spacing is different in the different planes. Heating the silicon in a nitrogen-containing ambient to form a thin layer of nitride and then growing the oxide through the thin nitrided layer reduces the difference in oxide thickness to less than 1%.
