摘要:
A method for depositing a copper seed layer onto a semiconductor substrate comprises applying a SCuD plating bath onto a surface of a substrate, rinsing the surface with an organic solvent, applying a co-reactant bath to the surface, and again rinsing the surface with an organic solvent. The SCuD plating bath is non-aqueous and comprises a copper precursor that is dissolved into an organic solvent. The co-reactant bath is also non-aqueous and comprises a co-reactant dissolved into an organic solvent. The SCuD plating bath may be heated before being applied to the substrate surface.
摘要:
Alignment of a laser apparatus is achieved by actively aligning components of the laser apparatus and then passively deriving an optical axis from that alignment. This passive derivation can be achieved by identifying features of an actively aligned optical element, deriving positional data for those features, and developing an optical axis from that positional data. The derivation of positional data may be performed over a particular coordinate system of an image taken of the feature, e.g., obtained by a vision system. The positional data and optical axis may be extrapolated out to a reference coordinate system for use in passively aligning other optical elements.

An exemplary method for making a memory structure comprises forming a first ferromagnetic layer, forming a spacer layer above the first ferromagnetic layer, forming a second ferromagnetic layer above the spacer layer by applying a first deposition process to form a thin layer of ferromagnetic material substantially covering the spacer layer, the first layer being formed at a first energy level, and applying a second deposition process to form the remainder of the second ferromagnetic layer above the thin layer of ferromagnetic material, the second ferromagnetic layer being formed at a second energy level, higher than the first energy level. This way, the spacer layer is protected by the thin layer during the second energy level deposition.

An exemplary memory array including a plurality of memory cells, each of the memory cells comprises a first ferromagnetic layer, a second ferromagnetic layer spaced apart from the first ferromagnetic layer by a non-magnetic separating layer and being magnetically coupled to the first ferromagnetic layer by demagnetizing fields from the first ferromagnetic layer, a spacer layer above the second ferromagnetic layer, and a reference layer above the spacer layer. The first ferromagnetic layer, non-magnetic separating layer, and second ferromagnetic layer in combination function as a data layer of the memory cell.

A magnetic tunnel junction device with a compositionally modulated electrode and a method of fabricating a magnetic tunnel junction device with a compositionally modulated electrode are disclosed. An electrode in electrical communication with a data layer of the magnetic tunnel junction device includes a high resistivity region that has a higher resistivity than the electrode. As a result, a current flowing through the electrode generates joule heating in the high resistivity region and that joule heating increases a temperature of the data layer and reduces a coercivity of the data layer. Consequently, a magnitude of a switching field required to rotate an alterable orientation of magnetization of the data layer is reduced. The high resistivity region can be fabricated using a plasma oxidation, a plasma nitridation, a plasma carburization, or an alloying process.

Provided is a pressure sensitive input device for data processing systems. In a particular embodiment, the device includes a transferable overlay for placement over a display screen of the system. Rows and columns of parallel conductors, which may be manufactured as ridges, are positioned to cross within the overlay, and are separated by a deformable isolation layer. A current is flowed across the rows and columns. Any change in the distance between the rows and columns, induced by the pressure of a user input, produces a disruption in the current flow. A proportional analog response signal is transmitted to a processor, wherein the signal is used to calculate a location of the user input, and a differential in the input pressure. The device may receive and process multiple, simultaneous inputs at various locations on the overlay. An appropriate method of use for the pressure-sensitive input device is also provided.

Methods, apparatus, and systems for testing, analyzing, and improving integrated circuit yield and quality are disclosed herein. For example, in one exemplary embodiment, one or more fault dictionaries are generated for identifying one or more defect candidates from corresponding observation point combinations. In this exemplary method, the observation point combinations indicate the observation points of a circuit-under-test that captured faulty test values upon application of a respective test pattern. Further, the one or more fault dictionaries in one embodiment are generated by: (a) for a first defect candidate, storing one or more first indicators indicative of test patterns detecting the first defect candidate, and (b) for a second defect candidate, storing at least a second indicator indicative of the test patterns that detect the second defect candidate, the second indicator comprising a bit mask that indicates which of the test patterns detecting the first defect candidate also detect the second defect candidate.
