Abstract: A hard disk drive (HDD) including a slider limiter. The HDD includes a spindle motor installed to a base member; at least one disk mounted to the spindle motor to be rotated by the spindle motor; an actuator moving a read/write head to a desired position on the at least one disk; and a ramp that is installed outside the at least one disk to park the read/write head when the at least one disk stops rotating. A slider limiter that is disposed between the flexures facing each other in order to limit vertical fluctuation of the slider is formed on the ramp. A step portion or a hollow space is formed in a portion of the slider limiter facing the slider, and a side-tab is protruded from both sides of the flexure to face the slider limiter on both sides of the hollow space.

Abstract: A sulfonated polyUrylene ether) copolymer, a method of preparing the same, and a polymer electrolyte membrane using the sulfonated poly(arylene ether) copolymer are provided. A sulfonated poly(arylene ether) copolymer containing a sulfonic acid is synthesized by poly condensing a dihydroxy monomer having a sulfonate group with a dihalide monomer, or by polycondensing a dihalide monomer having a sulfonate group with a dihydroxy monomer. Moreover, a crosslinkable dihydroxy monomer or a crosslinkable dihalide monomer is polycondensed with the obtained poly(arylene ether) copolymer, thus enable crosslinking between polymers. A polymer electrolyte membrane for a fuel cell formed using a poly(arylene ether) copolymer containing a crosslinkable moiety maintains the equivalent or superior levels to existing sulfonated poly(arylene ether) polymer or the Nafion membrane commercially available at present in terms of thermal stability, mechanical stability, chemical properties, film formability, and the like, and shows considerably improved proton conductivity and cell performances.

Abstract: Methods of forming a shallow trench isolation structures in semiconductor devices are disclosed. A disclosed method comprises forming a first oxide layer, a nitride layer, and a second oxide layer on a substrate; forming a trench defining first and second active areas by etching the second oxide layer, the nitride layer, the first oxide layer, and the substrate in a predetermined area; forming a third oxide layer along an inside of the trench; forming a fourth oxide layer to fill up the trench; forming a sacrificial oxide layer on the fourth oxide layer; and removing the sacrificial oxide layer, the fourth oxide layer, the third oxide layer, the second oxide layer, and the nitride layer so as to form the shallow trench isolation. Thus, it is possible to minimize the damage of a narrow active area when forming an element isolation area through an STI process.
