  • Enhanced EUV photoresist materials, formulations and processes
    Patent number: 11681227
    Abstract: The present disclosure relates to novel negative-type photoresist composition and methods of their use. The disclosure further relates to multiple trigger photoresist processes which allow for the improvement in contrast, resolution, and/or line edges roughness in some systems without giving up sensitivity. The photoresist compositions and the methods of the current disclosure are ideal for fine patent processing using, for example, ultraviolet radiation, extreme ultraviolet radiation, beyond extreme ultraviolet radiation, X-rays and changed particle. The disclosure further relates to sensitivity enhancing materials useful in the disclosed compositions and methods.

  • Biodegradable Nanoparticles Incorporating Highly Hydrophilic Positively Charged Drugs
    Publication number: 20080241257
    Abstract: Nanoparticles of a biodegradable polymer containing a hydrophilic, cationic drug, like streptomycin, and preparations containing the same, are disclosed. Pharmaceutical preparations containing the nanoparticles are administered, preferably orally, to individuals suffering from a disease or condition, and the nanoparticles release the drug, in vivo, to treat the disease or condition.
