摘要: A method of forming an integrated circuit is disclosed. A second material layer is formed on a first material layer. A patterned mask layer having a plurality of first features with a first pitch P1 is formed on the second material layer. The second material layer is etched by using the patterned mask layer as a mask to form the first features in the second material layer. The patterned mask layer is trimmed. A plurality of dopants is introduced into the second material layer not covered by the trimmed patterned mask layer. The trimmed patterned mask layer is removed to expose un-doped second material layer. The un-doped second material layer is selectively removed to form a plurality of second features with a second pitch P2. P2 is smaller than P1.

摘要: A method and apparatus for dispensing a liquid etchant onto a wafer dispenses the liquid etchant onto a wafer using a scanning dispensing nozzle while controlling the dispensing temperature of the etchant in real time as a function of the radial position of the dispensing nozzle over the wafer. The dispensing temperature of the etchant is controlled to enhance the effectiveness of the etchant and thus compensate for the lower etching rate zones in the wafer.
