    摘要: (i) As a primary reaction, m-cresol is allowed to react with propionaldehyde in the presence of an acid catalyst and thereby yields a polymer having a weight average molecular weight Mw of 200 to 500 and a molecular weight distribution Mw/Mn of 1.7 or less, and (ii) as a secondary reaction, the polymer is allowed to react with 3,4-xylenol and formaldehyde and thereby yields a novolak resin having an Mw of 1000 to 20000. By adding a specific photosensitizer, the novolak resin yields a positive photoresist composition.
