摘要： A method for controlling an ADI-AEI CD difference ratio of openings having different sizes is described. The openings are formed through a silicon-containing material layer, an etching resistive layer and a target material layer in turn. Before the opening etching steps, at least one of the opening patterns in the photoresist mask is altered in size through photoresist trimming or deposition of a substantially conformal polymer layer. A first etching step forming thicker polymer on the sidewall of the wider opening pattern is performed to form a patterned Si-containing material layer. A second etching step is performed to remove exposed portions of the etching resistive layer and the target material layer. At least one parameter among the parameters of the photoresist trimming or polymer layer deposition step and the etching parameters of the first etching step is controlled to obtain a predetermined ADI-AEI CD difference ratio.

摘要： A method for controlling ADI-AEI CD difference ratios of openings having different sizes is provided. First, a first etching step using a patterned photoresist layer as a mask is performed to form a patterned Si-containing material layer and a polymer layer on sidewalls thereof. Next, a second etching step is performed with the patterned photoresist layer, the patterned Si-containing material layer and the polymer layer as masks to at least remove an exposed portion of a etching resistive layer to form a patterned etching resistive layer. A portion of a target material layer is removed by using the patterned etching resistive layer as an etching mask to form a first and a second openings in the target material layer. The method is characterized by controlling etching parameters of the first and second etching steps to obtain predetermined ADI-AEI CD difference ratios.
