titleOfInvention |
Pattern formation method and material for manufacturing semiconductor devices |
abstract |
In the pattern forming method, a lower layer is formed over a base layer. An intermediate layer is formed over the lower layer. A resist pattern is formed over the intermediate layer. The intermediate layer is patterned by using the resist pattern as an etching mask. The underlying layer is patterned by using a patterned intermediate layer. The basal layer is patterned. The intermediate layer contains at least 50 wt % of silicon and organic materials. In one or more of the foregoing embodiments and the following embodiments, an annealing operation is further performed after the intermediate layer is formed. |
