A composition for removing a photoresist includes about 5 to about 20 percent by weight of an alcoholamide compound, about 15 to about 60 percent by weight of a polar aprotic solvent, about 0.1 to about 6 percent by weight of an additive, and pure water. The alcoholamide compound is chemically structured as follows: where R1 is a hydroxyl group or a hydroxyalkyl group, and R2 is a hydrogen atom or a hydroxyalkyl group.

A wafer transfer apparatus can transfer wafers to and from at least one process chamber quickly and in a small amount of space. The wafer transfer includes an arm unit, and a multi-blade connected to said arm unit so as to be rotatable relative to the arm unit. The multi-blade has at least two wafer supports configured to respectively support wafers as all lying in a horizontal plane. The arm unit includes a first arm mounted for rotation in a horizontal plane, and a second arm carried by the first arm and rotatable relative to the first arm in a horizontal plane. The multi-blade is carried by the second arm.

An antenna includes branches having substantially identical shapes. The branches are symmetrically disposed about a central point and extend along at least two concentric patterns whose geometric centers coincide with the central point. The branches each include pattern-forming portions that lie entirely within the concentric patterns, and at least one connecting portion extending between and connecting the pattern-forming portions. Input/output terminals for allowing a voltage to be impressed across the branches are provided at ends of each of the branches.

Provided is a vacuum pump having a rotation body cleaning unit. The vacuum pump includes a case provided with rotation guide holes at opposite end parts. The case includes a rotation body placed inside the case and including a rotation shaft having opposite ends rotatably supported by the rotation guide holes and a number of lobes provided in the rotation shaft at predetermined intervals. Further, a cleaning part is supported by the case and placed in a space between the lobes and cleans the rotation body.

A method of manufacturing a semiconductor device includes preparing a substrate on which a fuze line containing copper is formed. The method further includes cutting the fuze line by emitting a laser beam, and applying a composition for etching copper to the substrate to finely etch a cutting area of the fuze line and to substantially remove at least one of a copper residue and a copper oxide residue remaining near the cutting area. The composition for etching copper includes about 0.01 to about 10 percent by weight of an organic acid, about 0.01 to 1.0 percent by weight of an oxidizing agent, and a protic solvent.

Provided are methods and apparatus for exposing multiple substrates within a single exposing apparatus using only a single light source wherein a first substrate is exposed in a series of steps or shots during which light transmitted along a primary optical path is directed onto a primary surface of the substrate with the substrate being repositioned between sequential shots. A second substrate is exposed during the period of time while the first substrate is being repositioned by altering the optical path to divert the light from the light source into a secondary optical path that will expose a region on the second substrate. When the first substrate has been repositioned, the diversion of the light is terminated so that the light will again be transmitted along the primary optical path in order to expose the next sequential shot on the primary surface of the first substrate.
