    摘要： The present invention relates to a process of preparing syndiotactic styrenic polymers with a high conversion rate in the form of fine powder, which comprises (a) preparing styrenic polymers in a solid state by reacting a mixture consisting of styrenic monomers, a metallocene catalyst, a cocatalyst and inert organic solvent in a polymerization reactor, (b) separating a portion of the styrenic polymers from the reactor, (c) recycling the portion of the styrenic polymers in the reactor, and (d) reacting the recycled styrenic polymers with styrenic monomers. The styrenic monomers may include olefinic monomers. The monomers can be introduced to a single inlet or multiple inlets of the reactor. A single reactor or a plural number of reactors can be operated in the present invention. The plural numbers of reactors are arranged in series or in parallel. In the present invention, a self-cleaning mono- or twin-axis reactor can be employed to prevent the polymers from agglomerating on the inner wall or the axis. Alternatively, a cylindrical reactor can be employed, where the styrenic polymers are transported in a solid or powder state rotating in a certain direction at the range of Froude Number of from 0.1 to 10 and polymerization proceeds toward the exit of the reactor.

    摘要： An air shower head of an exposure device of photolithography equipment is free of chemical substances that could otherwise contaminate a photoresist layer on a semiconductor wafer and degrade the profile of the photoresist pattern. The air shower head is interposed between a lens system of the exposure device and a wafer stage, and has a hole in the middle thereof through which exposure light can pass to a wafer supported on the stage. The air shower head includes an upper frame defining a cavity open at the bottom thereof, and a porous bottom member covering the bottom of the upper frame. The porous member is mechanically secured to bottom ends of both the inner and outer side walls of the upper frame, i.e., without the use of chemical binders, to reduce the ability of the air shower head to serve as a source of contamination.
