摘要： A semiconductor device structure and method for manufacture includes a substrate having a top first layer; a second thin transition layer located on top of the first layer; and, a third layer located on top of the transition layer, wherein the second thin transition layer provides strong adhesion and cohesive strength between the first and third layers of the structure. Additionally, a semiconductor device structure and method for manufacture includes an insulating structure comprising a multitude of dielectric and conductive layers with respective transition bonding layers disposed to enhance interfacial strength among the different layers. Further, an electronic device structure incorporates layers of insulating and conductive materials as intralevel or interlevel dielectrics in a back-end-of-the-line (“BEOL”) wiring structure in which the interfacial strength between different pairs of dielectric films is enhanced by a thin intermediate transition bonding layer.

摘要： A method to electrolessly plate a CoWP alloy on copper in a reproducible manner that is effective for a manufacturable process. In the method, a seed layer of palladium (Pd) is deposited on the copper by an aqueous seeding solution of palladium acetate, acetic acid and chloride. Thereafter, a complexing solution is applied to remove any Pd ions which are adsorbed on surfaces other than the copper. Finally, a plating solution of cobalt (Co), tungsten (W) and phosphorous (P) is applied to the copper so as to deposit a layer of CoWP on the Pd seed and copper.

摘要： Embodiments of the invention provide a semiconductor device having dielectric material and its method of manufacture. A method comprises a short (≦2 sec) flash activation of an ILD surface followed by flowing a precursor such as silane, DEMS, over the activated ILD surface. The precursor reacts with the activated ILD surface thereby selectively protecting the ILD surface. The protected ILD surface is resistant to plasma processing damage. The protected ILD surface eliminates the requirement of using a hard mask to protect a dielectric from plasma damage.

摘要： A metal interconnect layer that fills in a via hole formed by first depositing a first Al--Cu film on the sidewalls of the via hole at a low temperature and a low sputtering power and then depositing a second Al--Cu film on the first Al--Cu film at a high temperature and high sputtering power. Sputtering is performed in two steps at low and high temperatures within the same sputtering chamber. The deposition at low temperature and low sputtering power provides good coverage in the via hole, and the deposition at high temperature and high sputtering power reduces the process time.

摘要： A multilayer interconnect structure for a semiconductor integrated circuit comprising a base layer of titanium, a second layer of titanium nitride, a third layer of an aluminum alloy and a top layer of titanium nitride. All of the layers contained within the multilayer interconnect structure are deposited by in-situ deposition in an ultra-high vacuum deposition system. The different layers deposited in the deposition system are conducted consecutively without a disruption to the vacuum. Although each layer in the multilayer interconnect structure are deposited within the integrated ultra-high vacuum deposition system, with multiple deposition chambers, the deposition of the different layers is conducted at different temperatures. The time to the electromigration failure of the multilayer interconnect structure, caused by the electromigration of the aluminum alloy, is greatly increased by depositing the aluminum alloy layer at a temperature in excess of 300.degree. C. and preferably between 350.degree. C. and 550.degree. C. The titanium layer and the adjacent titanium nitride layer below the aluminum alloy layer provide the interconnect structure with low resistivity and prevent alloy spiking of the base substrate. As a result, a multilayer interconnect structure provided that has improved electromigration reliability and a low resistance, thereby enabling more dense applications within an integrated circuit.
