abstract = {Yttrium-Aluminum-Garnet (YAG) is an advanced structural
ceramic that has desirable properties for halogen plasma
etching chambers used in semiconductor processing. The trend
towards more aggressive etching environments requires new
material systems with enhanced plasma resistance. To tackle
this issue, there is an increasing interest in understanding
the specific erosion mechanisms of etch-resistant ceramics.
In this study, we present a novel approach to manufacture
highly dense ceramics with garnet structure by means of
reactive spark plasma sintering of the respective oxides.
Targeting on improved plasma resistance compared to YAG, Y
was completely replaced by lanthanides (Lu, Yb, Er) enabling
us to clarify the role of these lanthanides in the YAG-type
structure on the plasma-material interaction. For
characterization, all samples were exposed to fluorine-based
etching plasmas (CF4/O2/Ar) using an inductively coupled
plasma (ICP) etch chamber. The resulting topography was
characterized by atomic force microscopy (AFM). Under the
given conditions, no physical erosion could be detected and
the formation of a reaction layer was the dominating
phenomenon. The induced chemical gradient has been analyzed
by means of SIMS and STEM. Our results reveal the reaction
layer is significantly altered if Y is replaced by
lanthanides, which provides a route to study mechanisms of
the plasma corrosion process.},
