A chemically amplified negative resist composition comprising (A) a quencher in the form of an onium salt containing an anion (Xq−) which forms a conjugate acid (XqH) having a boiling point of lower than 165° C. and a molecular weight of up to 150, (B) a base polymer, and (C) a photoacid generator exhibits a high resolution and forms a pattern of satisfactory profile with low LER, fidelity and improved dose margin.

The invention provides a patterned material and substrate intermediate coating composition as well as application and a device thereof. The composition comprises matrix resin A, matrix resin B, a thermally induced acid generator and a solvent, the acid dissociation constant pKa of conjugated acid corresponding to anions in the thermally induced acid generator is lower than-3; the matrix resin A and the matrix resin B both contain cross-linkable groups and are cross-linked at 150-300 DEG C; the molar ratio of the cross-linking groups in the matrix resin A to the cross-linking groups in the matrix resin B is 1: (0.6-1.3). The molar ratio of cross-linking groups in the matrix resin A and the matrix resin B is controlled at 150-300 DEG C in the presence of the thermally induced acid generator, so that a high cross-linking state is realized, and the phenomenon that an upper-layer patterned material falls off is avoided; strong cross-linked structures can be formed on various substrates, and the applicability is high.

The application discloses an adhesion compound based on metal inorganic compound for optimizing adhesion performance and a preparation method and application thereof, and belongs to the technical field of biological adhesives. The adhesion compound comprises an adhesion precursor, the adhesion precursor is composed of a protein-polyphenol composite hydrogel and a hydrogen bond breaking small molecule compound, and can perform network reconstruction containing beta-fold formation in an aqueous phase containing a metal inorganic compound; the metal inorganic compound has the following characteristics: (a) the solubility of itself and / or a hydrolysis product in water at 25 DEG C is less than 0.2 g / 100 mL; (b) the dissociation constant of a conjugate acid of an adapted anion is greater than 5; (c) the dissolution process produces one or more than one of water, gas or non-metallic precipitates. The application discloses for the first time that the release of metal cations is accurately adjusted by adapting metal inorganic compounds to directionally drive the network reconstruction of the adhesion precursor into a dense advanced structure, and the local metal ion concentration is avoided from being too high to produce stimulation to human tissues, the in-vivo adhesion performance is optimized, and the safe and durable soft and hard tissue bonding effect is achieved.
