Additional supplies of liquid polyimide materials for semiconductor applications are coming on the market with the start-up of a second HD MICROSYSTEMS L.L.C. plant in Parlin, New Jersey. The new facility turns out high-molecular-weight polyimide coatings and photodefinable polyimides -- materials that are used for stress buffer and wafer overcoat as well as for dielectric and passivation layers in chips and thin-film packages. Year-old- plus HD MicroSystems, equally owned by HITACHI CHEMICAL CO., LTD. and E.I. DUPONT DE NEMOURS & CO., INC., spent approximately $12 million to build a facility with a Class 10,000 cleanroom manufacturing area, a Class 100 cleanroom for filtration and bottling and a Class 10 cleanroom for quality control and functional testing. The new plant in Parlin, which roughly doubles capacity at that location, manufactures the same products as the joint venture's Yamazaki Works in Hitachi City, Ibaraki prefecture.
