Publication number: 20130089716Abstract: The invention described herein is directed towards spin-on carbon materials comprising polyamic acid compositions and a crosslinker in a solvent system. The materials are useful in trilayer photolithography processes. Films made with the inventive compositions are not soluble in solvents commonly used in lithographic materials, such as, but not limited to PGME, PGMEA, and cyclohexanone. However, the films can be dissolved in developers commonly used in photolithography. In one embodiment, the films can be heated at high temperatures to improve the thermal stability for high temperature processing. Regardless of the embodiment, the material can be applied to a flat/planar or patterned surface. Advantageously, the material exhibits a wiggling resistance during pattern transfer to silicon substrate using fluorocarbon etch.Type: ApplicationFiled: October 10, 2012Publication date: April 11, 2013Applicant: BREWER SCIENCE INC.Inventor: Brewer Science Inc.

Publication number: 20130078397Abstract: An insulated glass sealant includes an elastomeric matrix that is the reaction product of a carboxyl-terminated polymer and a polycarbodiimide. A method of sealing an insulated glass unit includes applying the insulated glass sealant to one or more glass sheets, a spacer to be disposed between the glass sheets, or both; and contacting the one or more glass sheets with the spacer to define an annular space between the glass sheets and to produce the insulated glass unit. The sealants maintain the excellent attributes of traditional polyurethane sealants, such as low water swell, low moisture vapor transmission, good adhesion to the window frame, low migration of the insulating gas, and good workability, but without the use of polyisocyanates in the curing process. Methods for making the sealant and for sealing insulated glass panels, such as glass windows, with these rugged sealants, and the resulting articles, are also provided.Type: ApplicationFiled: September 22, 2011Publication date: March 28, 2013Applicant: Cray Valley USA, LLCInventors: Herbert Shin-I Chao, Nan Tian
