摘要： A method of selectively altering material properties of a substrate in one region while making a different alteration of material properties in an adjoining region is provided. The method includes selectively masking a first portion of the substrate during a first exposure and selectively masking a second portion of the substrate during a second exposure. Additionally, a mask may be formed having more than one thickness where each thickness will selectively reduce the amount of energy from a blanket exposure of the substrate thereby allowing a substrate to receive different levels of energy dosage in a single blanket exposure.

摘要： A method of forming airgaps is provided where a blocking mask is applied to a substrate to shield a portion of the substrate from a beam of energy. After irradiation, the blocking mask is removed and a capping material is applied to the substrate. Alternatively, the capping material may be applied before irradiation. The capping material is perforated to allow an etchant to pass therethrough to the substrate below the capping material. The exposed portions of the substrate are removed from underneath the capping material by etching. The capping material is then sealed leaving sealed airgaps within the substrate.

摘要： Prevention of damage to an interlevel dielectric (ILD) is provided by forming an opening (e.g., trench) in the ILD, and sputtering a dielectric film onto a sidewall of the opening by overetching into a layer of the dielectric below or within the ILD during forming of the opening. The re-sputtered film protects the sidewall of the opening from subsequent plasma/ash processes and seals the porous dielectric surface along the sidewall and bottom without impacting overall process throughput. A semiconductor structure resulting from the above process is also disclosed.

摘要： A device, system and method for evaluating reliability of a semiconductor chip are disclosed. Strain is determined at a location of interest in a structure. Failures are evaluated in a plurality of the structures after stress cycling to determine a strain threshold with respect to a feature characteristic. Structures on a chip or chips are evaluated based on the feature characteristic to predict reliability based on the strain threshold and the feature characteristic. Predictions and design changes may be made based on the results.

摘要： Methods for sealing an organic ILD layer and a metal layer after an etching step. The method includes etching through an ILD layer and leaving a remaining portion of an underlying metal layer cap, maintaining the device in an inert gas, and depositing at least a portion of a liner into the opening to seal the ILD layer and the metal layer. Subsequent processing may include formation of a via by etching through the portion of the liner and the remaining portion of the cap layer, and depositing a metal.
