摘要:
Organic coating compositions, particularly antireflective coating compositions, are provided that comprise that comprise a diene/dienophile reaction product. Preferred compositions of the invention are useful to reduce reflection of exposing radiation from a substrate back into an overcoated photoresist layer and/or function as a planarizing, conformal or via-fill layer.
摘要:
A mask is described for forming an image on a substrate. The mask may be selectively applied to a radiant energy sensitive material on the substrate. Actinic radiation applied to the composite chemically changes portions of the radiant energy sensitive material not covered by the mask. The mask and portions of the radiant energy sensitive material are removed using a suitable aqueous base developer. The mask is composed of aqueous base soluble or dispersible polymers and light-blocking agents.
摘要:
Iron containing substrates are electrically polarized in a pre-plating composition containing one or more sulfonic acids and one or more grain refiners, the pre plating composition activates the surface of the steel substrate to receive thin tin or tin alloy. The thin tin or tin alloy is electroplated onto the activated surface of the steel substrate. The thin tinplate and alloy have reduced amounts of pores in the surface.
摘要:
Polyarylene oligomer compositions having improved adhesion to surfaces as compared to conventional polyarylene oligomers are useful in forming dielectric material layers in electronics applications.
摘要:
Reaction products of amines and polymers containing saturated heterocyclic moieties may be used as levelers in metal electroplating baths. The reaction products may plate metal with good surface properties and good physical reliability.
摘要:
Reaction products of halogenated pyrimidines and nucleophilic linker units are included in metal electroplating baths to provide good throwing power. The electroplating baths can be used to plate metal, such as copper, tin and alloys thereof on printed circuit boards and semiconductors and fill through-holes and vias.
摘要:
Indium electroplating compositions containing 2-imidazolidinethione compounds electroplate substantially defect-free uniform layers which have a smooth surface morphology on metal layers. The indium electroplating compositions can be used to electroplate indium metal on metal layers of various substrates such as semiconductor wafers and as thermal interface materials.
摘要:
Polyarylene oligomers formed from an aromatic dialkyne monomer having a solubility enhancing moiety show improved solubility in certain organic solvents and are useful in forming dielectric material layers in electronics applications.
摘要:
A polymeric material having a negative photoelastic constant. The polymeric material comprises: (a) a polymer comprising polymerized units of 2-vinylpyridine, 4-vinylpyridine, methyl methacrylate or a combination thereof; (b) a C9-C25 aliphatic polycyclic compound; and (c) an organic compound having a boiling point of at least 200° C.
