    摘要: Polyacrylate materials having certain heterocyclic nuclei within the structure have been found to be readily and polymerizable by irradiation in air. Typically, polyacrylate materials are highly sensitive to the presence of oxygen and do not polymerize fully unless special precautions or conditions are undertaken.

    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.
