A photoresist polymer comprising a fluorine component, a photoresist composition containing the photoresist polymer and an organic solvent to reduce surface tension, and a method for manufacturing a semiconductor device using the same by forming a photoresist film uniformly on the whole surface of an underlying layer pattern to allow a subsequent ion-implanting process to be performed stably. A chip designed for performing the method and detecting the bioluminescence is also provided. If not, one of the first or second video calling devices might prompt the caller to leave a videomail message, and might record and upload the videomail message to a server over a network for post-processing andor storage. When a call is received for processing by a skillsplit, the router sends it to the skillsplit queue that presently has the shortest EWT, and increments that EWT by the corresponding AAT. A plurality of pins are carried by each connector to secure each connector to the upper or lower chord member and to the respective bottom or top end portions of the diagonal members.
