To provide an aqueous adhesive for an inorganic material with excellent adhesiveness to the inorganic material. An adhesive improver (J) for an aqueous adhesive of an inorganic material including a (co) polymer (A) containing an unsaturated (poly) carboxylic acid (anhydride) (al) as a constituent monomer, wherein a weight-average molecular weight of the (co) polymer (A) is 6,000 to 200,000; and an aqueous adhesive for an inorganic material (X) including the adhesive improver (J) for an aqueous adhesive of an inorganic material, a saccharide (B), a polycarboxylic acid (C) having 4 to 24 carbon atoms, and water.

Methods are disclosed to prepare permanent materials that can be coated onto microelectronic substrates or used for other structural or optical applications. The materials are thermally stable to at least about 300 C., curable using a photo or thermal process, exhibit good chemical resistance (including during metal passivation), and have a lifespan of at least about 5 years, preferably at least about 10 years, in the final device. Advantageously, these materials can also be bonded at room temperature. The materials exhibit no movement or squeeze-out after bonding and adhere to a variety of substrate types.

An x-ray window can include an adhesive layer sandwiched between and providing a hermetic seal between a thin film and a housing. The adhesive layer can include liquid crystal polymer. The liquid crystal polymer can be opaque, gas-tight, made of low atomic number elements, able to withstand high temperature, low outgassing, low leakage, able to relieve stress in the x-ray window thin film, capable of bonding to many different materials, or combinations thereof.
