Abstract
The present invention provides a composition for treating a semiconductor in which etching of silicon germanium is suppressed and a ratio of an etching rate of silicon to an etching rate of silicon germanium is large. In addition, the present invention provides a method for treating an object to be treated using a composition for treating a semiconductor. The composition for treating a semiconductor according to the present invention is a composition for treating a semiconductor including a quaternary ammonium salt having a hydroxyl group, a polar organic solvent, at least one nitrogen-containing compound selected from the group consisting of a compound represented by Formula (1), a compound represented by Formula (2), and salts thereof, and water, in which the mass ratio of the nitrogen-containing compound to the quaternary ammonium salt is 0.00001 to 0.1.
