Abstract: A method of manufacturing a semiconductor device includes forming an active region on a substrate, forming a gate structure on the substrate intersecting the active region, removing an upper portion of the gate structure and forming a gate capping layer, forming a preliminary contact plug electrically connected to a portion of the active region, the preliminary contact plug including first and second portions, forming a mask pattern layer including a first pattern layer covering an upper surface of the gate capping layer, and a second pattern layer extending from the first pattern layer to cover the second portion of the preliminary contact plug, and forming a contact plug using the mask pattern layer as an etch mask by recessing the first portion of the preliminary contact plug exposed by the mask pattern layer to a predetermined depth from an upper surface of the preliminary contact plug.

Abstract: Methods and systems for ascertaining factors contributing to the temperature of a device. A method includes monitoring a plurality of parameters that are contributing to a temperature of the device. The method also includes estimating a degree of contribution of internal factors to the temperature of the device based on the monitored plurality of parameters and a battery temperature of a battery of the device. The method further includes estimating a degree of contribution of external factors to the temperature of the device, based on the monitored plurality of parameters and a battery temperature of a battery of the device. A neural network can be used for estimating the temperature of the ambience of the device and the impacts of internal and external factors on temperature of the device.
