Beschreibung
Zusammenfassung:	The invention provides photoresists and resist preparative methods. Methods of the invention include treatment of a resist resin with methylene chloride or other organic solvent to remove low molecular weight materials. It has been found that the treated resin can be formulated into resists that provide manufactured electronic devices with significantly reduced defects.
