The proximity effect in superconducting-normal (SN) bilayer thin films plays an important role in the design of superconducting devices such as TES and KID. This presentation focuses on McMillan's formula, which describes the transition temperature of NS bilayers, and organizes its relationship with other formulas, such as those by Cooper and Martinis, while clarifying their applicability ranges. McMillan's formula, with its broader applicability, is recommended for device researchers. The proximity effect in SS bilayer thin films is also discussed.
