ABSTRACT:
Process solutions comprising one or more surfactants are used to reduce the number of defects in the manufacture of semiconductor devices. In certain preferred embodiments, the process solution of the present invention may reduce post-development defects such as pattern collapse when employed as a rinse solution either during or after the development of the patterned photoresist layer. Also disclosed is a method for reducing the number of pattern collapse defects on a plurality of photoresist coated substrates employing the process solution of the present invention.
