摘要： Embodiments of the invention generally provide methods for etching a substrate. In one embodiment, the method includes determining a substrate temperature target profile that corresponds to a uniform deposition rate of etch by-products on a substrate, preferentially regulating a temperature of a first portion of a substrate support relative to a second portion of the substrate support to obtain the substrate temperature target profile on the substrate, and etching the substrate on the preferentially regulated substrate support. In another embodiment, the method includes providing a substrate in a processing chamber having a selectable distribution of species within the processing chamber and a substrate support with lateral temperature control, wherein a temperature profile induced by the substrate support and a selection of species distribution comprise a control parameter set, etching a first layer of material and etching a second layer of material respectively using different control parameter sets.

摘要： A two-step method of etching an organic coating layer, in particular, an organic antireflection coating (ARC) layer, is disclosed. During the main etch step, the organic coating layer is etched using a plasma generated from a first source gas which includes a fluorocarbon and a non-carbon-containing, halogen-comprising gas. Etching is performed using a first substrate bias power. During the overetch step, residual organic coating material remaining after the main etch step is removed by exposing the substrate to a plasma generated from a second source gas which includes a chlorine-containing gas and an oxygen-containing gas, and which does not include a polymer-forming gas. The overetch step is performed using a second substrate bias power which is less than the first substrate bias power. The first source gas and first substrate bias power provide a higher etch rate in dense feature areas than in isolated feature areas during the main etch step, whereas the second source gas and second substrate bias power provide a higher etch rate in isolated feature areas than in dense feature areas during the overetch step, resulting in an overall balancing effect.
摘要翻译：公开了蚀刻有机涂层，特别是有机抗反射涂层（ARC）层的两步法。在主蚀刻步骤期间，使用由包括碳氟化合物和非含碳卤素气体的第一源气体产生的等离子体蚀刻有机涂层。使用第一衬底偏置功率进行蚀刻。在过蚀刻步骤期间，通过将衬底暴露于由包含含氯气体和含氧气体的第二源气体产生的等离子体而将主蚀刻步骤后剩余的残留有机涂层材料除去，并且不包括聚合物形成气体。使用小于第一衬底偏置功率的第二衬底偏置功率来执行过蚀刻步骤。在主蚀刻步骤期间，第一源气体和第一衬底偏置功率在致密特征区域中提供比在隔离特征区域中更高的蚀刻速率，而第二源气体和第二衬底偏置功率在隔离特征区域中提供比在在疏浚过程中密集的特征区域，导致整体平衡效果。
