    摘要: Addition of non-nitrogen containing weak acids to amine-containing alkaline strippers for photoresists produce stripper compositions able to strip highly cross-linked or hardened photoresist films without producing any substantial metal corrosion. Weak acids useful in the stripping compositions include those having a pK in aqueous solution of 2.0 or higher and an equivalent weight of less than about 140 and are employed in an amount to neutralize from about 19% to about 75% of the amine present in the stripper composition.

    摘要: System, apparatus and method for efficiently and effectively isolating analytes from a liquid sample by solid phase extraction comprises a workstation platform with a plurality of suction providing stations for receiving either or both a detachably mounted collection chamber housing a removable collection vessel and membrane holder with removable, screen supported disc membrane, the holder having an inlet opening for receiving a liquid and a passageway through the screen supported disc membrane to an exit port for flow and collection, at the appropriate time, of analytes, extraction solvent, or liquid sample. The membrane holder is adapted to be releasably mounted into either the suction stations or the collection chamber. The removable collection vessel in the collection chamber enables prompt, timely, safe and effective removal of solvent, analyte or liquid from the system. The workstation platform is preferably rotatable for ease of access to the plurality of suction providing stations.

    摘要: 2-diazo-1-ones are useful deep UV photoresist solubility modification agents exhibiting improved photosensitivity allowing shorter deep UV exposure times to achieve the same extent of photoreaction as with prior art solubility modification agents. The 2-diazo-1-one solubility modification agents when used as photoactive solubility modification components in photoresist compositions permit the photoresist compositions to act as either positive or negative photoresist compositions depending upon the developer employed, namely, as a positive resist when a metal ion containing developer is employed and as a negative resist when a metal ion free developer is employed.
