摘要： An atomic layer deposition method is used to deposit a TiN or TiSiN film having a thickness of about 50 nm or less on a substrat. A titanium precursor which is tetrakis(dimethylamido)titanium (TDMAT), tetrakis(diethylamido)titanium (TDEAT), or Ti{OCH(CH3)2}4 avoids halide contamination from a titanium halide precursor and is safer to handle than a titanium nitrate. After a monolayer of the titanium precursor is deposited on a substrate, a nitrogen containing reactant is introduced to form a TiN monolayer which is followed by a second purge. For TiSiN, a silicon source gas is fed into the process chamber after the TiN monolayer formation. The process is repeated several times to produce a composite layer comprised of a plurality of monolayers that fills a contact hole. The ALD method is cost effective and affords an interconnect with lower impurity levels and better step coverage than conventional PECVD or CVD processes.

摘要： A new and improved method for electroplating a metal onto a substrate in such a manner as to render the metal essentially corrosion-resistant during subsequent substrate processing such as chemical mechanical polishing. The process involves incorporating nitrogen into the metal as the metal is electroplated onto the substrate. The process includes preparing the electroplating bath, placing a leveler chemical containing nitrogen in the prepared bath, circulating the leveler chemical throughout the bath and then electroplating the metal on the substrate. In a preferred embodiment, alkyl polyamide, alkyl amine, alkyl amine oxide or thiourea with molecular weight ranging from 100˜1,000,000 is used as the leveler chemical.

摘要： A method for integrating low-K materials in semiconductor fabrication. The process begins by providing a semiconductor structure having a dielectric layer thereover, wherein the dielectric layer comprising an organic low-K material. The dielectric layer is patterned to form pillar openings. A pillar layer is deposited over the semiconductor structure; thereby filling the pillar openings with the pillar layer. The pillar layer is planarized to form pillars embedded in said dielectric layer. The pillar layer comprises a material having good thermal stability, good structural strength, and good bondability of spin coating back-end materials, improving the manufacturability of organic, low-K dielectrics in semiconductor fabrication. In one embodiment, the pillars are formed prior to forming dual damascene interlayer contacts. In another embodiment, pillars are formed simultaneously with interlayer contacts.

摘要： A process for performing CMP in two steps is described. After trenches have been formed and over-filled with copper, in a first embodiment of the invention a hard pad is used initially to remove most of the copper until a point is reached where dishing effects would begin to appear. A soft pad is then substituted and CMP continued until all copper has been removed, except in the trenches. In a second embodiment, CMP is initiated using a pad to which high-pressure is applied and which rotates relatively slowly. As before, this combination is used until the point is reached where dishing effects would begin to appear. Then, relatively low pressure in combination with relatively high rotational speed is used until all copper has been removed, except in the trenches. Both of these embodiments result in trenches which are just-filled with copper, with little or no dishing effects, and with all traces of copper removed everywhere except in the trenches themselves.

摘要： Within a dual damascene method for forming a dual damascene aperture within a microelectronic fabrication there is employed a first etch stop layer formed of a first material and a second etch stop layer formed of a second material. One of the first material and the second material is a non-nitrogenated silicon carbide material and the other of the first material and the second material is a nitrogenated silicon carbide material. By employing the first material and the second material, there may be etched completely through the first etch stop layer to reach a contact region formed there beneath while not etching completely through the second etch stop layer to reach a first dielectric layer formed there beneath.
