Abstract: A semiconductor memory device includes a third insulating pattern and a first insulating pattern on a substrate, the third insulating pattern and the first insulating pattern being spaced apart from each other in a first direction that is perpendicular to the substrate such that a bottom surface of the third insulating pattern and a top surface of the first insulating pattern face each other, a gate electrode between the bottom surface of the third insulating pattern and the top surface of the first insulating pattern, and including a first side extending between the bottom surface of the third insulating pattern and the top surface of the first insulating pattern, and a second insulating pattern that protrudes from the first side of the gate electrode by a second width in a second direction, the second direction being different from the first direction.

Abstract: Provided is a method for treating a substrate. The method for treating the substrate may include heating a substrate formed with a plurality of thin film layers including a photoresist layer formed on a surface, and irradiating light to a first thin film layer including a metal among the plurality of thin film layers to heat the first thin film layer.

Abstract: Disclosed is an example method of displaying a notification on a device with a plurality of operating systems (OSes) installed therein. The method includes identifying a first OS displayed on a first display of the device among the plurality of OSes, detecting a notification generated in a second OS running in a background of the device among the plurality of OSes, converting the generated notification based on a preset format of the first OS when the notification is generated, and displaying the converted notification on the first display on which the first OS is displayed.

Abstract: Provided is a method of operating a device having a plurality of operating systems installed therein, the method including: receiving a first user input for selecting at least one application installed in a first operating system among the plurality of operating systems; receiving a second user input for selecting a second operating system, in which a shortcut icon for execution of the selected application is to be displayed, among the plurality of operating systems; creating the shortcut icon based on the first user input and the second user input; and displaying the created shortcut icon on a user interface of the second operating system.
