An epoxy-containing siloxane-modified resin, a package material, and a package structure are provided. The epoxy-containing siloxane-modified resin is formed by reacting a hydroxy terminated siloxane compound with a siloxane resin, and then reacting with an epoxy silane. The hydroxy terminated siloxane compound and the siloxane resin have a molar ratio of 5:1 to 10:1, and the epoxy silane and the siloxane resin have a molar ratio of 2:1 to 4:1.

An adhesive for separatably attaching a support to a circuit side of a wafer to process a rear surface of the wafer, the adhesive including a component (A) that is cured by a hydrosilylation reaction and a component (B) containing a phenyl group-containing polyorganosiloxane, wherein a ratio in % by mass of the component (A) to the component (B) is 95:5 to 30:70. A separation method including applying the adhesive onto a first body to form an adhesion layer, attaching a second body to the adhesion layer, heating the adhesion layer from a side of the first body to cure the adhesive to form a layered body, processing the layered body, and carrying out separation between the adhesion layer, and the first and second bodies. The processing may be polishing the rear surface of the wafer.

A method of coating at least one silica capillary using a novel dual ligand sol-gel sorbent and method of manufacture of such sorbent is provided herein. The dual ligand sol-gel sorbent provides superior enrichment effects through simultaneous exploitation of superhydrophobicity of one of the ligands and the ability of the other ligand to undergo π-π interaction with hydrophobic aromatic analytes. Sorbent performance is enhanced both in terms of analyte enrichment and sorbent stability, such as pH stability and solvent stability.
