A cable tightening device includes a fixed unit, a rotation member rotatably mounted on the fixed unit, a movable unit mounted on the rotation member and movable relative to the fixed unit to drive the rotation member to rotate relative to the fixed unit in a oneway direction, and a locking unit mounted between the fixed unit and the movable unit to releasably lock the movable unit onto the fixed unit. Thus, the movable unit is locked onto the fixed unit by the locking unit to lock the cable tightening device and the cable so as to protect the cargo wound by the cable, thereby achieving an anti-theft purpose.

A method of fabricating a semiconductor device, a process of fabricating a through substrate via and a substrate with through vias are provided. The substrate with through vias includes a semiconductor substrate having a back surface and a via penetrating the back surface, a metal layer, a first insulating layer and a second insulating layer. The first insulating layer is formed on the back surface of the substrate and has an opening connected to the through via. The second insulating layer is formed on the first insulating layer and has a portion extending into the opening and the via to form a trench insulating layer. The bottom of the trench insulating layer is etched back to form a footing portion at the corner of the via. The footing portion has a height less than a total height of the first and second insulating layers.

A recording medium. A recording layer is disposed overlying a substrate. A moisture barrier layer is disposed overlying the recording layer. A reflecting layer is disposed overlying the moisture barrier layer. An adhesion layer is disposed overlying the reflecting layer. Due to the static moisture barrier layer interposed between the reflecting layer and the recording layer in an embodiment of the invention, moisture interpenetration from ambience can be diminished to improve weather and corrosion resistance of the recording medium.
