Abstract:
A semiconductor device (e.g., a non-volatile memory device) with improved data retention characteristics includes active regions that protrude above a top surface of a device isolation region. A tunneling insulating layer is formed on the active regions. Charge storage patterns (e.g., charge trap patterns) are formed so as to be spaced apart from each other. A blocking insulating layer and a gate are formed on the charge storage patterns.
Abstract:
A dual capacity compressor, which can maintain a fixed eccentricity and stable operation, even when the compressor is rotated in both the regular and reverse directions in order to provide multiple compression capacities, is provided. This dual capacity compressor implements an improved key member and associated key member fitting parts to inhibit relative motion of the crank pin and the eccentric sleeve during operation, so as to reduce or eliminate a destabilizing effect due to centrifugal forces on the eccentric sleeve and external forces applied through the connecting rod.
Abstract:
A heating apparatus using an electromagnetic wave is disclosed, by which cut-of performance of an electromagnetic wave is enhanced by increasing an electromagnetic wave absorption bandwidth having cut-off performance below −70 dB. The present invention includes a door provided to an open front side of a body to be opened/closed and a choke filter having a panel type choke part arranged by at least one row each along an edge of the door and a filter part arranged by at least one row each along an edge of the choke part and having a plurality of slots, wherein a prescribed choke part is provided to a most inner side among rows of the choke and filter part.
