Abstract: A die alignment method includes vertically aligning a first die comprising first magnetic patterns and a second die comprising second magnetic patterns with each other using magnetic force between the first magnetic patterns and the second magnetic patterns. Each of the first magnetic patterns and the second magnetic patterns comprises a horizontally magnetically anisotropic material. The first magnetic patterns and the second magnetic patterns do not vertically overlap each other when the first die and the second die are vertically aligned with each other.

Abstract: A photo-decomposable compound includes an anion component including an adamantyl group and a cation component including a C5 to C40 cyclic hydrocarbon group and forming a complex with the anion component. At least one of the adamantyl group and the cyclic hydrocarbon group has a substituent, which decomposes by acid and generates an alkali soluble group. The substituent includes an acid-labile protecting group. A photoresist composition includes a chemically amplified polymer, the photo-decomposable compound, and a solvent. To manufacture an integrated circuit (IC) device, a photoresist film is formed using the photoresist composition on a feature layer, a first area of the photoresist film is exposed to generate a plurality of acids from the photo-decomposable compound in the first area, the chemically amplified polymer is deprotected due to the plurality of acids, and the first area is removed to form a photoresist pattern.
