Patent number: 7332262Abstract: A method for forming a patterned amorphous carbon layer in a semiconductor stack, including forming an amorphous carbon layer on a substrate and forming a silicon containing photoresist layer on top of the amorphous carbon layer. Thereafter, the method includes developing a pattern transferred into the resist layer with a photolithographic process and etching through the amorphous carbon layer in at least one region defined by the pattern in the resist layer, wherein a resist layer hard mask is formed in an outer portion of the photoresist layer during etching.Type: GrantFiled: June 16, 2005Date of Patent: February 19, 2008Assignee: Applied Materials, Inc.Inventors: Ian Latchford, Christopher Dennis Bencher, Yuxiang Wang, Mario Dave Silvetti

Patent number: 7329477Abstract: The present invention provides a process for using an amine contamination-protecting top-coating composition. Preferably, the amine contamination-protecting top-coating composition of the present invention comprises an amine contamination-protecting compound. Useful amine contamination-protecting compounds include amine derivatives; amino acid derivatives; amide derivatives; urethane derivatives; urea derivatives; salts thereof; and mixtures thereof. The amine contamination-protecting top-coating composition of the present invention reduces or eliminates problems such as T-topping due to a post exposure delay effect and/or difficulties in forming a fine pattern below 100 nm due to acid diffusion associated with conventional lithography processes involving a photoresist polymer containing an alicyclic main chain using a light source, such as KrF (248 nm), ArF (193 nm), F2 (157 nm), E-beam, ion beam and extremely ultraviolet (EUV).Type: GrantFiled: November 19, 2004Date of Patent: February 12, 2008Assignee: Hynix Semiconductor Inc.Inventors: Jae Chang Jung, Keun Kyu Kong, Hyeong Soo Kim, Jin Soo Kim, Cha Won Koh, Sung Eun Hong, Geun Su Lee, Min Ho Jung, Ki Ho Baik

Patent number: 7326525Abstract: Disclosed herein are top anti-reflective coating polymers used in a photolithography process, methods for preparing the anti-reflective coating polymer, and anti-reflective coating compositions comprising the disclosed anti-reflective coating polymers. The top anti-reflective coating polymers are used in immersion lithography for the fabrication of a sub-50 nm semiconductor device. The top anti-reflective coating polymer is represented by Formula 1 below: wherein R1, R2 and R3 are independently hydrogen or a methyl group; and a, b and c represent the mole fraction of each monomer, and are independently in the range between about 0.05 and about 0.9. Because the disclosed top anti-reflective coatings are not soluble in water, they can be used in immersion lithography using water as a medium for the light source. In addition, since the top anti-reflective coatings can reduce the reflectance from an underlayer, the uniformity of CD is improved, thus enabling the formation of ultrafine patterns.Type: GrantFiled: March 16, 2005Date of Patent: February 5, 2008Assignee: Hynix Semiconductor Inc.Inventor: Jae-chang Jung

Patent number: 7316874Abstract: Methods of forming a patterned semiconducting-dielectric material on a substrate by thermal processes are disclosed, comprising heating a thermally imageable donor element comprising a substrate and a transfer layer of semiconductive material in conjunction with a dielectric. The donor is exposed with the positive image of the desired pattern to be formed on the receiver, such that the exposed portions of the layer of semiconductive and dielectric material are simultaneously transferred, forming the desired pattern of semiconductive and dielectric material on the receiver. The semiconducting material can be patterned to form a thin film transistor. The method can also be used to pattern a light-emitting polymer or small molecule in conjunction with the charge injection layer to form the light-emitting display for light-sensitive organic electronic devices. Donor elements for use in the process are also disclosed.Type: GrantFiled: March 23, 2004Date of Patent: January 8, 2008Assignee: E. I. du Pont de Nemours and CompanyInventor: Graciela Beatriz Blanchet-Fincher
