Title: Etching of selected part of laminate in plasma treatment chamber and decrease of side wall polymer deposition during etching
Inventor: NAEEM MUNIR D
IPC: H01L21/3065
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To easily remove the polymer deposition generated during etching by applying high sputtering component etching to at least a part of a first barrier layer and further low sputtering component etching to at least a part of a metallic treatment layer, respectively. SOLUTION: The high sputtering component etching advantageously increases the sputtering of a photoresist layer, allows additive carbon to exist in an etching reactor and this carbon to be absorbed in the side wall deposition. This deposition is made more soluble by increasing the carbon quantity of the side wall deposition and may be made easily removable during the subsequent photoresist stripping and washing stage. The metal treatment layer is usually substantially thicker than the apex barrier layer of most of the laminates and, therefore, the use of the low sputtering component etching to etch the metal treatment layer in order to lessen photoresist corrosion is recommended.
