    Abstract: A method for forming a field-effect transistor with a raised drain structure is disclosed. The method includes depositing a low-k inter-metal layer over a semiconductor substrate, depositing a porogen-containing low-k layer over the low-k inter-metal layer, and etching a space for the via through the low-k inter-metal layer and the porogen-containing low-k layer. The method further includes depositing a metal layer, a portion of the metal layer filling the space for the via, another portion of the metal layer being over the porogen-containing low-layer, removing the portion of the metal layer over the porogen-containing layer by a CMP process, and curing the porogen-containing low-k layer to form a cured low-k layer.

    Abstract: A method of fabricating a semiconductor integrated circuit (IC) is disclosed. The method includes receiving a precursor. A decomposable polymer layer (DPL) is deposited between the conductive features of the precursor. The DPL is annealed to form an ordered periodic pattern of different types of polymer nanostructures. One type of polymer nanostructure is decomposed by a first selectively to form a trench. The trench is filled by a dielectric layer to form a dielectric block. The remaining types of polymer nanostructures are decomposed by a second selectively etching to form nano-air-gaps.
