Abstract
An antireflective layer formed from boron-doped amorphous carbon may be removed using a process which is less likely to over etch a dielectric layer than conventional technology. This layer may be removed by exposing the layer to an oxygen plasma (i.e. an “ashing” process), preferably concurrently with the ashing and removal of an overlying photoresist layer. An inventive process which uses the inventive antireflective layer is also described.

An in-process semiconductor device, comprising:
- an antireflective layer comprising amorphous carbon having a boron concentration of between about 0.1 atom % and about 20 atom %.
An antireflective layer used during the fabrication of an electronic device, comprising:
- an antireflective layer comprising amorphous carbon having a boron concentration of between about 0.1 atom % and about 20 atom %.
