PROBLEM TO BE SOLVED: To allow selective formation of air gaps in a semiconductor device. SOLUTION: A first dielectric material 1 having contact holes is made of hydrogenated silicon oxycarbide (SiCO:H). By using a UV/ozone treatment including an oxidizer or a process of oxidizing supercritical carbon dioxide or the like, the sidewall of each contact hole is converted into a modified material 4 containing less carbon than the first dielectric material 1. A barrier layer 5 and a copper portion 6 are formed in each contact hole. After that, the modified material 4 is removed by etching using HF to leave an air gap there. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a method and a detector for detecting a defect in a coating layer of a device. SOLUTION: The present invention relates to an optical method for executing an optical method for detecting the integrity of a material system. This method is provided with optical inspection before and after a solvent absorption step. A underlying layer deposited on a semiconductor substrate is coated based on whether a solvent is absorbed or not, and the existence of the defect, or non-existence thereof is determined in a protection layer for the underlying layer. The method may be used in a processing level, for example, the presence of the defect in the coating layer formed on the semiconductor substrate is determined in manufacture of the electronic device to decide the capability of further processing for the device, or the necessity of removal from the processing.
