摘要:
By digitizing the UFM signal without using a lock-in amplifier, substantially all of the information initially contained in the UFM output signal may be maintained and may then be used for further data processing. Consequently, any type of model or evaluation algorithm may be used without being restricted to a very narrow bandwidth, as is the case in lock-in based techniques. The digitizing is performed on a real-time basis, wherein a complete UFM curve is digitized and stored for each scan position. In this way, quantitative meaningful values for specific surface-related characteristics with a nanometer resolution may be obtained.

In a semiconductor device, capacitors may be formed so as to be in direct contact with a transistor by using a shared transistor region, such as a drain region or a source region of closely spaced transistors, as one capacitor electrode, while the other capacitor electrode is provided in the form of a buried electrode in the dielectric material of the contact level. To this end, dielectric material may be deposited so as to reliably form a void, wherein, at any appropriate manufacturing stage, a capacitor dielectric material may be provided so as to separate the capacitor electrodes.

Methods and systems are provided for fabricating a semiconductor device. An exemplary method involves forming a feature of a semiconductor device in a first region of a layer of material on a semiconductor substrate and forming a test structure in a second region of the layer of material. The test structure is formed concurrently to forming the feature, and a dimension of the feature is determined using the test structure.

During the fabrication of microstructure devices, such as integrated circuits, particles may be analyzed by displacing or removing the particles from the device surface and subsequently performing an analysis process. Consequently, a well-defined measurement environment may be established after removal of the particles, which may be accomplished on the basis of nanoprobes and the like. Hence, even critical surface areas may be monitored with respect to contamination and the like on the basis of well-established analysis techniques.

A capacitor is formed in nano channels in a conductive body. Embodiments include forming a source contact through a first inter layer dielectric (ILD), forming a conductive body on the first ILD, forming a second ILD on the conductive body, forming drain and gate contacts through the second ILD, conductive body, and first ILD, forming nano channels in the conductive body, forming an insulating layer in the channels, and metalizing the channels. An embodiment includes forming the nano channels by forming a mask on the second ILD, the mask having features with a pitch of 50 nanometers (nm) to 100 nm, etching the second ILD through the mask, etching the conductive body through the mask to a depth of 80% to 90% of the thickness of the conductive body, and removing the mask.

A semiconductor device with reduced defect density is fabricated by forming localized metal silicides instead of full area silicidation. Embodiments include forming a transistor having a gate electrode and source/drain regions on a substrate, forming a masking layer with openings exposing portions of both the gate electrode and source/drain regions over the substrate, depositing metal in the openings on the exposed portions, forming silicides in the openings, and removing unreacted metal and the masking layer.

A stress compensation region that may be appropriately positioned on a package substrate may compensate for or at least significantly reduce the thermally induced mechanical stress in a sensitive metallization system of a semiconductor die, in particular during the critical reflow process. For example, a stressor ring may be formed so as to laterally surround the chip receiving portion of the package substrate, wherein the stressor ring may efficiently compensate for the thermally induced deformation in the chip receiving portion.
摘要:
Thermally induced stress in a semiconductor die, i.e., in a complex metallization system thereof, may be reduced by “dividing” a package substrate into two or more substrate sections, which may have formed therebetween an appropriate stress buffer region, for instance a region of superior resiliency. In this case, the total deformation of the package substrate may be reduced, thereby also reducing the thermally induced stress forces in the complex metallization system of the semiconductor die. Hence, for a given size and complexity of a metallization system, an increased production yield and superior reliability may be achieved.
摘要:
In sophisticated semiconductor devices, manufacturing techniques and etch masks may be formed on the basis of a mask layer stack which comprises an additional mask layer, which may receive an opening on the basis of lithography techniques. Thereafter, the width of the mask opening may be reduced by applying a selective deposition or growth process, which thus results in a highly uniform and well-controllable adjustment of the target width of the etch mask prior to performing the actual patterning process, for instance for forming sophisticated contact openings, via openings and the like.
