An electronic device is provided which includes a housing including a through-hole positioned in a side face, a socket disposed within the housing, and having an entrance aligned with the through-hole, a biasing member mounted on the housing, and disposed between the through-hole and the entrance of the socket, and a tray in which at least one storage medium is seated. The tray is inserted into/extracted from the housing through the through-hole, and inserted into the socket from the inside of the housing through the entrance. During the insertion or extraction of the tray, the biasing member may limit a movement range of the storage medium in the tray.

Electronic device with detachable storage medium

Disclosed are various embodiments relating to an electronic device that includes a key An electronic device may include a housing having a through-hole formed therein. A key may be exposed through the through-hole and configured to be pressed. A key switch may be located on a rear surface of the key, wherein the key structure may be configured to enable the key to be pressed and to detect the press of the key. Moreover, a structure provided on a lower portion of the housing may be able to bear a pressure exerted by a user when pressing the key in a direction opposite the housing. Further, a dummy detachably provided between the housing and the structure, wherein the dummy, when being attached, may support the key and the key switch such that both are capable of being pressed in the through-hole toward the direction of the structure.

Electronic device including key

An electronic device includes a support member, an ornamental member that is assembled to face one face of the support member, and an operating member that is disposed on the support member to be partially exposed to the outside through the ornamental member. The operating member includes a body that is positioned on one face of the support member to be exposed through the ornamental member, and at least one pair of fastening pieces, each of which extends from the body to be fastened to the support member. Other embodiments are also disclosed.

Electronic device

The present invention provides a method of fabricating trench isolation structures of a semiconductor device. A conformal trench filler insulation layer is formed to fill wide and narrow trenches in a substrate. A portion of the trench filler insulation layer filling the wide trench is then removed. Next, a trench protection layer is formed on the trench filler insulation layer. The resultant structure is planarized to leave the trench protection layer over the wide width trench. Another planarization process is then carried out using the etch mask pattern and the remaining trench protection layer as a planarization stopper. Accordingly, the device isolation layer will attain a uniform planarity irrespective of the various widths of the trenches.
