Abstract: Techniques are provided for fabricating a semiconductor integrated circuit device which implement an interlayer dielectric (ILD) layer replacement process to replace an initial sacrificial ILD layer with a low-k ILD layer, while forming silicide or dielectric capping layers to protect source/drain contacts of field-effect transistor devices from etch damage during the ILD replacement process. For example, source/drain contact openings (e.g., trenches) are formed in a sacrificial ILD layer and metallic source/drain contacts are formed in the source/drain contact openings. Protective capping layers (e.g., metal-semiconductor alloy capping layers or dielectric capping layers) are formed on upper surfaces of the metallic source/drain contacts. The sacrificial ILD layer is removed using an etch process to etch down the sacrificial ILD layer selective to the protective capping layers, and a low-k ILD layer is formed in place of the removed sacrificial ILD layer.

Abstract: Determination logic for a cloud content states framework is described herein. In implementations, a framework is configured to perform operations for management of cloud content files at the computing device on behalf of cloud storage providers. Determination logic for the framework is utilized to make state determinations in dependence upon a defined set of file sync properties. The framework operates to make assessments of the file sync properties and set states for files in accordance with the assessments. In implementations, file sync properties are related to corresponding states through a mapping data structure that maps file sync property values to different states and enables look-ups of states based on property values. The framework utilizes and references the mapping data structure to match file sync properties identified for cloud content files to corresponding states and then set states for the cloud content files accordingly.

Abstract: A switch receives a first packet, where the first packet includes a source media access control MAC address. The switch obtains a first flapping count corresponding to the source MAC address. The switch determines, based on the first flapping count, whether a loop failure occurs in a network in which the switch is located. When the loop failure occurs in the network in which the switch is located, the switch obtains a flapping port set corresponding to the source MAC address. The switch determines a primary port in the plurality of ports, where the primary port is a port that must be suppressed. The switch enables a flooding suppression function on the primary port, where the flooding suppression function is used to suppress forwarding of a received flooding packet by the primary port.
