权利人:TOKYO OHKA KOGYO CO LTD
摘要:The invention provides an improvement over the conventional positive-working photoresist compositions comprising a novolac resin and an ester compound between 2,3,4-trihydroxybenzophenone and naphthoquinone-1,2-diazido-5-sulfonic acid in respect of scum formation in development and resistance of the patterned photoresist layer against heat and dry etching. The inventive composition comprises, in addition to the novolac resin and the ester compounds, 2,3,4-trihydroxybenzophenone in a specified amount relative to the ester compounds as a part of the photosensitive component which may be a reaction product obtained by the esterification reaction for the synthesis of the ester compounds containing unesterified 2,3,4-trihydroxybenzophenone.

摘要:A process for producing an aromatic ether which comprises using a phenol and an oxirane compound as raw materials and reacting the phenol with the oxirane compound in the presence of an aromatic ether, characterized in that a catalyst having an anion-exchangeable group is used for the reaction. The process is suitable also for mass synthesis. Even when aromatic ethers which are the target compound and a by-product are present in the reaction system from the beginning, the high-quality target compound can be efficiently produced with a satisfactory selectivity while inhibiting the target compound from reacting with the starting materials to generate a by-product.
