A chemically amplified resist composition comprising a quencher containing a quaternary ammonium iodide, dibromoiodide, bromodiiodide or triiodide, and an acid generator exhibits a sensitizing effect and an acid diffusion suppressing effect and forms a pattern having improved resolution, LWR and CDU.

The invention discloses an ether bond breaking method of phenyl alkyl ether. The ether bond breaking method comprises the following step: in an organic solvent, in the presence of aluminum triiodide and an inorganic acid scavenger, performing an ether bond breaking reaction on the phenyl alkyl ether from -20 DEG C to the refluxing temperature to produce phenol and derivatives thereof. The ether bond breaking method is mild in condition, easy to operate and high in yield, and is suitable for a wide range of phenyl alkyl ether.

The invention provides a method for preparing rhodium triiodide, belonging to a noble metal catalyst and mainly solving the problems of economical efficiency and environment friendliness in preparation of the rhodium triiodide catalyst. The rhodium triiodide is generated by nano rhodium powder and a hydroiodic acid solution by electrolysis. The method comprises the following steps: 1, adding a potassium iodide solution of iodine and the nano rhodium powder into a U-shaped electrolytic cell, and loading alternating current between two electrodes, till the rhodium powder is dissolved to generate a rhodium iodate solution; 2, filtering the electrolyte, washing, distilling the filtrate to separate out excessive hydrogen iodide and water from the filtrate and obtain a rhodium iodate concentrate, and then crystallizing the rhodium iodate concentrate in a crystallization furnace to obtain rhodium triiodide; and 3, recycling the distilled hydroiodic acid solution and water. In the preparation method of the rhodium triiodide, the primary reaction conversion rate of rhodium is high (more than or equal to 99.9%), the yield and the purity are high; and the method is economic, environment-friendly, simple in operation and low in cost.
