Abstract: A device includes a fin extending from a semiconductor substrate; a gate stack over the fin; a first spacer on a sidewall of the gate stack; a source/drain region in the fin adjacent the first spacer; an inter-layer dielectric layer (ILD) extending over the gate stack, the first spacer, and the source/drain region, the ILD having a first portion and a second portion, wherein the second portion of the ILD is closer to the gate stack than the first portion of the ILD; a contact plug extending through the ILD and contacting the source/drain region; a second spacer on a sidewall of the contact plug; and an air gap between the first spacer and the second spacer, wherein the first portion of the ILD extends across the air gap and physically contacts the second spacer, wherein the first portion of the ILD seals the air gap.

Abstract: An electronic device and a method for managing a user interface include setting a movement speed of the interface elements in the user interface corresponding to an angle of change of the electronic device, and setting a movement direction of the interface elements in the user interface corresponding to rotation direction. The method further includes confirming the movement speed and the movement direction of the interface elements in the user interface according to the angle of change and the rotation direction, and controlling the interface elements in the user interface to according to the confirmed movement speed and movement direction.

Abstract: A mobile device and a method for operating the mobile device are provided. The method initializes the mobile device to support a multitasking environment, and synchronously executing multiple software applications in the multitasking environment. The method generates a user interface on a home screen of the mobile device, and divides the user interface into multiple display areas according to a total number of the executed software applications. The method receives an input command from a keypad of the mobile device, and generates a key input event according to the input command. In addition, the method controls different software applications to communicate with each other according to the key input event, and displays an execution result of each of the executed software applications on a corresponding display area of the user interface.

Abstract: An image browsing management method detects a touch operation of a user's finger on a touch screen, and analyzes the touch operation to determine a touch type. Then, the method further calls a corresponding pointer program to process the touch operation according to the touch type, so as to adjust or update the image, for example, delete the image, display a next image, a previous image, a next calendar month image, or a previous calendar month image.
