    • PURPOSE: A method and a system of post-deposition treating a carbon-containing layer on a substrate are provided to improve the oxidation resistance or loss resistance of a film by using a processing mode for generating treatment plasma or the treatment plasma. CONSTITUTION: An analytical recording data of electron spectroscopy/X-ray photoelectron spectro-scanning for chemical analysis performed on the variation of the chemical composition and coupling structure of an SiC layer, which is deposited on a dielectric layer and exposed to treatment plasma, such as He plasma and N2O plasma are produced. As a result, the coupling structure is fixed through the He plasma treatment. The surface composition of the SiC layer is changed by N2O plasma treatment and becomes to contain many C-C or C-H couplings and in addition, protects Si dangling couplings or other dangling couplings. The coupling variation on the surface strengthens adhesion of the SiC layer to the next layer. N2O oxidizes the thin portion of the layer through controlled exposure and forms a surface having a higher resistance with respect to deeper oxidation as compared with an untreated layer.
    • 目的:提供一种沉积处理基板上的含碳层的方法和系统,以通过使用用于产生处理等离子体的处理模式或处理等离子体来提高膜的耐氧化性或耐损耗性。 构成:用于化学分析的电子光谱/ X射线光电子分光扫描的分析记录数据,其对沉积在介电层上并暴露于处理等离子体的SiC层的化学组成和耦合结构的变化进行,例如 因为他制造了等离子体和N2O等离子体。 结果,通过He等离子体处理固定了耦合结构。 通过N2O等离子体处理改变SiC层的表面组成,并且变成含有许多C-C或C-H接头,并且另外保护Si悬挂接头或其它悬挂接头。 表面上的耦合变化增强了SiC层与下一层的粘合性。 N2O通过受控曝光氧化层的薄部分,与未处理层相比,形成相对较深氧化具有较高电阻的表面。
