IMPLANTING WITH IMPROVED UNIFORMITY AND ANGLE CONTROL ON TILTED WAFERS
摘要:
A system, method and program product for improving uniformity and angle control wafers being implanted. A system is provided that includes an end station for positioning a wafer being implanted, comprising: a platen for holding the wafer, wherein the platen is rotatable to provide wafer rotation; a housing for holding the platen, wherein the housing is rotatable about a first orthogonal axis to provide a first type of wafer tilt; a structure for supporting the housing, wherein the structure is rotatable about a second orthogonal axis to provide a second type of wafer tilt; and a control system which, during an implant process of the wafer, causes wafer rotation, the first type of wafer tilt, and the second type of wafer tilt.
