Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device of high strength that lowers an effective dielectric constant k eff , maintains an inter-level vertical capacity in an interconnection at a low level and a manufacturing method of the same. SOLUTION: The method of manufacturing the device comprises a step for providing a structure having an insulating layer 120 of at least one interconnection 130 and a step for forming a sublithographic template mask 150 on the insulating layer. A sublithographic feature 135a is formed in the vicinity of at least one intereconnection by performing etching on the insulating layer through the sublithographic template mask using a selective etching step.

Abstract: A semiconductor device which includes an improved liner structure formed in a via having extended sidewall portions and a bottom penetrating a metal line. The liner structure includes two liner layers, the first being on the via sidewalls, but not the bottom, and the second being on the first layer and the extended sidewall portions and bottom of the via. A method of making the liner structure, in which the first layer is deposited prior to an etching or cleaning step, which extends the via into the metal line, is also disclosed.

Abstract: Method of improving the resistance of a metal against degradation from exposure to fluorine released from a fluorine-containing material by forming a fluorine-barrier layer between the insulator material and the metal. The invention is especially useful in improving corrosion and poisoning resistance of metallurgy, such as aluminum metallurgy, in semiconductor structures. The invention also covers integrated circuit structures made by this method.
