Abstract: The present invention provides a multi-function laparoscopic surgical instrument that meets niche needs in the expanding field of Minimally Invasive Surgery (MIS). A preferred embodiment of the present invention comprises a sheath that may be inserted into a patient, wherein the sheath contains at least two interchangeable surgical instruments that may be advanced into or retracted from the patient through a single outlet in the sheath. It is intended for use in laparoscopic and thoracoscopic surgical procedures, including intra-abdominal, intra-thoracic, intra-pelvic and arthroscopic MIS procedures, and is particularly well suited to single incision laparoscopic surgery and Natural Orifice Translumenal Endoscopic Surgery (NOTES).

Abstract: Post chemical mechanical polishing (CMP) cleaning methods are disclosed which reduce integrated circuit defects. A corrosion inhibitor is preferably applied during the post-CMP cleaning steps after application of a first chemistry. Subsequent to the application of the corrosion inhibitor a rinsing step using deionized water is employed. In this manner, the corrosion inhibitor applied during the post-CMP clean fills voids created in previous passivation layers by previous chemistries. Also, existing post-CMP equipment may be used to implement the preferred embodiments of the present invention. Preferably the corrosion inhibitor applied during the post-CMP clean is benzotriazole (BTA).
