Publication number: 20140193755Abstract: An electrical field is applied through an extreme ultraviolet (EUV) photoresist layer along a direction perpendicular to an interface between the EUV photoresist layer and an underlying layer. Secondary electrons and thermal electrons are accelerated along the direction of the electrical field, and travel with directionality before interacting with the photoresist material for a chemical reaction. The directionality increases the efficiency of electron photoacid capture, reducing the required EUV dose for exposure. Furthermore, this directionality reduces lateral diffusion of the secondary and thermal electrons, and thereby reduces blurring of the image and improves the image resolution of feature edges formed in the EUV photoresist layer. The electrical field may be generated by applying a direct current (DC) and/or alternating current (AC) bias voltage across an electrostatic chuck and a conductive plate placed over the EUV photoresist layer with a hole for passing the EUV radiation through.Type: ApplicationFiled: January 7, 2013Publication date: July 10, 2014Applicant: International Business Machines CorporationInventors: Richard S.
