    摘要: The present invention provides a process kit for a semiconductor processing chamber. The processing chamber is a vacuum processing chamber that includes a chamber body defining an interior processing region. The processing region receives a substrate for processing, and also supports equipment pieces of the process kit. The process kit includes a pumping liner configured to be placed within the processing region of the processing chamber, and a C-channel liner configured to be placed along an outer diameter of the pumping liner. The pumping liner and the C-channel liner have novel interlocking features designed to inhibit parasitic pumping of processing or cleaning gases from the processing region. The invention further provides a semiconductor processing chamber having an improved process kit, such as the kit described. In one arrangement, the chamber is a tandem processing chamber.

    摘要: A process for selectively removing photoresist, organic overlayers, and/or polymers/residues from a substrate without altering the surface chemistry and adhesion properties of the underlying substrate layers is provided. Generally, the process includes pretreating the substrate with hydrogen (e.g., by way of a hydrogen-based plasma) prior to deposition of a photoresist layer, and then ashing the substrate with a hydrogen-based plasma to selectively remove the photoresist, organic overlayers, and/or polymers/residues from the substrate during etching, post-etch, rework, etc. The hydrogen-based ashing process of the invention may be used post-etch to remove the residue photoresist, or may be used in a rework stripping process to remove misaligned patterns. The hydrogen-based ashing process following the initial hydrogen surface pretreatment substantially reduces surface chemistry poisoning, while retaining adequate adhesion properties following ashing.

    摘要: We have reduced the critical dimension bias for reticle fabrication. Pattern transfer to the radiation-blocking layer of the reticle substrate essentially depends upon use of a hard mask to which the pattern is transferred from a photoresist. The photoresist pull back which occurs during pattern transfer to the hard mask is minimalized. In addition, a hard mask material having anti-reflective properties which are matched to the reflective characteristics of the radiation-blocking layer enables a reduction in critical dimension size and an improvement in the pattern feature integrity in the hard mask itself. An anti-reflective hard mask layer left on the radiation-blocking layer provides functionality when the reticle is used in a semiconductor device manufacturing process.
