Abstract:
Provided are a rotation joint capable of compensating for a mismatch due to thermal expansion and a semiconductor device having the same. The rotation joint can include a support member and a first contact member coupled to a first portion of the support member such that a surface of the first contact member is moveable relative to a surface of the support member adjacent to the first contact member. The first contact member can include solder material.
Abstract:
Provided are a semiconductor package and a manufacturing method thereof. The semiconductor package includes a flexible film with a film wire region formed of a film substrate region on which a semiconductor chip is mounted, and a plurality of sub film wires branching and extending from the film substrate region and electrically connected to the semiconductor chip. A plurality of external contact terminals arranged on the outer surface of the flexible film and electrically connected to the semiconductor chip is further included. Also included is a plurality of conductive patterns having first pads disposed in the flexible film, arranged on the film substrate region, and electrically connected to one of the plurality of external contact terminals; and second pads arranged on the film wire region and electrically connected to the semiconductor chip.
Abstract:
Provided is a wafer level chip scale package that reduces the parasitic capacitance generated between ball pads and the solder balls, and enhances the joint reliability between the ball pads and the solder balls. The wafer level chip scale package provides a conductive pattern in each ball pad section, on which a solder ball is mounted, so as to have a spiral or mesh shape, provides a space defined by the conductive pattern such that a first dielectric layer under the conductive pattern is exposed, and provides the solder ball on a top surface of each ball pad section such that part of the solder ball is inserted into the space defined by the conductive pattern. When viewed from the top, the dielectric layer is exposed from each ball pad section by an area of about 50% or less.
Abstract:
The present invention discloses a content protection system in a storage medium and the method of the same. The storage medium includes a flash disk, a memory card, a hard disk, a CDR, or a MO. In one aspect of the present invention, the content protection system in a storage medium includes a database; a partitioning module coupled to the database to partition the storage medium; and a link table managing module coupled to the database to establish and manage a link table of a file to be stored in the storage medium.
