The difference in the silicon content results in different etch rate with respect to oxygen plasma which makes dry developing possible.Type: GrantFiled: February 23, 2001Date of Patent: August 19, 2003Assignee: Korea Advanced Institute of Science and TechnologyInventors: Jin-Baek Kim, Jae-Jun Lee, Jae-Sung Kang

Patent number: 6599968Abstract: Compounds and compositions comprising specific metal salts of bicyclo[2.2.1]heptane dicarboxylate salts in order to provide highly desirable properties within polyolefin articles are provided. The inventive salts and derivatives thereof are useful as nucleating and/or clarifying agents for such polyolefin, provide excellent crystallization temperatures, stiffness, and calcium stearate compatibility within target polyolefin. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Polyolefin additive compositions and methods of producing polyolefin with such compounds are also contemplated within this invention.Type: GrantFiled: November 3, 2001Date of Patent: July 29, 2003Assignee: Milliken & CompanyInventors: Xiaodong Edward Zhao, Darin L. Dotson, Brian M. Burkhart, Jeffrey R. Jones

Patent number: 6589707Abstract: The present invention provides photoresist monomers, photoresist polymers derived from the same, processes for producing such photoresist polymers, photoresist compositions comprising such polymers, and processes for producing a photoresist pattern using such photoresist compositions. In particular, photoresist monomers of the present invention comprise a moiety of Formula 4: where R1, R2, R3 and R4 are those defined herein. Photoresist polymers of the present invention have a relatively high etching resistance, and therefore are useful in a thin resist process and a bilayer photoresist process. Moreover, photoresist polymers of the present invention have a high contrast ratio between an exposed region and a non-exposed region.Type: GrantFiled: February 15, 2001Date of Patent: July 8, 2003Assignee: Hyundai Electronics Industries Co., Ltd.Inventors: Geun Su Lee, Jae Chang Jung, Min Ho Jung, Ki Ho Baik
