Abstract
An apparatus for evaluating a performance of a plasma-polymerized polymer layer using a UV spectrometer, including a polymerizing chamber for forming a polymerized polymer layer on a surface of a substrate by plasma discharging, a UV probe mounted contactless to the polymerized polymer layer formed in the polymerizing chamber and transmitting/receiving UV to and from the polymer layer and a UV spectrometer analyzing a signal inputted from the UV probe. With this apparatus, the characteristic of the surface of the substrate having a polymer layer consecutively polymerized by plasma can be evaluated in a contactless way, and the evaluation can be performed without affecting the process parameters such as the degree of vacuum within the chamber.
