    摘要: The present invention provides photoresist materials for use in photolithography at wavelengths less than about 248 nm. More particularly, the photoresists of the invention are particularly suited for use in 157 nm lithography. A photoresist composition of the invention includes a polymer having at least one monomeric unit having an aromatic moiety. The monomeric unit further includes at least a group, such as an electron withdrawing group, attached to the aromatic moiety. The attached group includes at least one CF bond. The polymer further includes an acidic hydroxyl group. A photoresist composition of the invention can have an absorbance in a range of 1-5 &mgr;m−1 at 157 nm, rendering it particularly suitable for use as a single layer resist in 157 nm lithography.

    摘要: A photoacid-generating photoresist composition sensitized with an aromatic, multi-ring, heterocylcic nitrogen containing sensitizer, preferably a ring extended phenothiazine derivative. The use of the sensitizer permits exposure of photoresists to near UV irradiation where such photoresists have heretofore been exposed to deep UV irradiation. The invention is especially useful for acid hardening photoresist systems.

    摘要: Lead-free solder compositions for bonding and sealing flat panel displays, CCD's, solar cells, light emitting diodes, and other optoelectronic devices are disclosed. The solders are based on alloys of Sn, Au, Ag, and Cu and one or more rare earth metals chosen from the following, Y, La, Ce, Pr, Sc, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. Optionally, the compositions may comprise In, Bi, or Zn. The solder compositions exhibit superior bonding capability in joining dissimilar surfaces such as those present in both the flat panel display and light emitting devices. Additionally the solders provide a strong barrier to the diffusion of both water and oxygen into these devices thus promoting longer device life times.
