SIMULATION ON THE TEMPERATURE DISTRIBUTION OF ICE FIXED ABRASIVES POLISHING KEYWORDS ICE FIXED ABRASIVES POLISHING SINGLE SILICON WAFER TEMPERATURE DISTRIBUTION FINITE ELEMENT METHOD ABSTRACT THE KEY QUESTION IN THE ICE FIXED ABRASIVES IFA POLISHING IS HOW TO KEEP SUITABLE AMBIENT TEMPERATURE IN PRODUCTION PROCESS IN ORDER TO AVOID PREMATURE FAILURE OF THE IFA BASED ON ABOVE THE THREE DIMENSIONS FINITE ELEMENT ANALYSIS FEA MODEL OF IFA POLISHING TEMPERATURE FIELD IS BUILT UP AT FIRST THEN THE MODEL RELIABILITY IS DEMONSTRATED BY EXPERIMENTS EFFECTS OF AMBIENT TEMPERATURE AND POLISHING TIME ON TEMPERATURE DISTRIBUTION AND MELTING RATE OF THE IFA PAD ARE RESEARCHED THE RESULTS SHOW THAT THE AMBIENT TEMPERATURE SHOULD BE KEPT AT ABOUT 10 C IN ORDER TO CONTROL THE MELTING RATE OF THE IFA PAD EFFECTIVELY AND KEEP LONGER POLISHING TIME ALL THE RESULTS PROVIDE THE BASIS FOR CHOOSING SUITABLE AMBIENT TEMPERATURE IN POLISHING INTRODUCTION SOME DEFECTS OF THE MACHINED SURFACE SUCH AS RESIDUAL STRESS MICRO CRACKS AND SURFACE DAMAGES CAN BE DECREASED IN THE CRYOGENIC CONDITIONS 1 IN RECENT YEARS SOME POLISHING TESTS OF HARD AND BRITTLE MATERIALS IN THE PRESENCE OF CRYOGENIC POLISHING PAD CONTAINING COLLOIDAL SIO2 SLURRY NANO SIZED CEO2 OR AL2O3 SLURRY WERE CARRIED OUT AND SMOOTH SURFACES WITH NANOMETER OR SUB NANOMETER ROUGHNESS HAVE BEEN OBTAINED 2 4 HOWEVER DURING CRYOGENIC POLISHING THE QUANTITY OF HEAT PRODUCTION IN THE POLISHING REGION CAN LEAD TO THE THAWING OF IFA POLISHING PAD ON THE ONE HAND WITH THE POLISHING CARRIES ON UNCEASINGLY THE ABRASIVES IN THE SUPERFICIAL COAT OF THE POLISHING PAD CAN PULL OFF AND THE NEW ONES CAN EMERGE CONTINUOUSLY THUS THE REMOVAL EFFICIENCY OF POLISHING CAN BE IMPROVED ON THE OTHER HAND THE MELTING RATE OF THE IFA POLISHING PAD SHOULD BE CONTROLLED EFFECTIVELY TO AVOID THE WASTE OF ABRASIVES AND ENSURE THE EFFICIENCY OF IFA DURING POLISHING THEREFORE IN THE CONDITION OF ENSURING THE POLISHING TIME THE MELTING RATE OF THE IFA POLISHING PAD SHOULD BE CONTROLLED STRICTLY TO KEEP HIGH REMOVAL RATE USING COMPUTER SIMULATION TECHNOLOGY THE POLISHING PROCESS CAN BE SIMULATED BY BUILDING UP FEA MODEL OF TEMPERATURE DISTRIBUTION OF IFA POLISHING THE CHANGES OF TEMPERATURE AND MELTING RATE OF THE IFA POLISHING PAD WITH AMBIENT TEMPERATURE CAN BE DISPLAYED DIRECTLY CONSEQUENTLY ACCORDING TO THESE CHANGES WHICH TEMPERATURE DISTRIBUTION AND MELTING RATE ARE BENEFICIAL TO THE POLISHING CAN BE PREDICTED HOWEVER FEW STUDIES WITH RESPECT TO THE TEMPERATURE DISTRIBUTION OF IFA POLISHING HAVE BEEN CARRIED OUT THIS PAPER AIMS TO BUILD UP FEA MODEL OF TEMPERATURE DISTRIBUTION OF IFA POLISHING AND INVESTIGATE THE EFFECTS OF AMBIENT TEMPERATURE AND POLISHING TIME ON TEMPERATURE DISTRIBUTION AND MELTING RATE OF THE IFA PAD ANALYSIS OF TEMPERATURE DISTRIBUTION FIG 1 SHOWS THE IFA POLISHING APPARATUS AS FIG 1 SHOWS THE ICE PAD IS ASSOCIATED WITH THE MACHINE SPINDLE THROUGH THE THREAD OF DIE AND ROTATES TOGETHER WITH THE SPINDLE THE PRESSURE HEAD IS ASSOCIATED WITH THE AIR CYLINDER AND DRIVEN BY IT THE APPLIED PRESSURE IS CONTROLLED BY THE CYLINDER 1 THE WORK PIECE IS MOUNTED ON AN OBJECT CARRIER DURING THE CRYOGENIC POLISHING THOUGH THE TEMPERATURE OF THE ICE PAD IS VERY LOW THE AMBIENT TEMPERATURE IN THE WORKING AREA IS ABOVE 0 C AND ACCORDING TO THE THEORY OF TRIBOCHEMISTRY HIGH TEMPERATURE AND HIGH PRESSURE CAN BE PRODUCED AT THE LOCAL CONTACT POINT BETWEEN THE ABRASIVES AND THE WORK PIECE DURING THE POLISHING SO THE TEMPERATURE AT THE CONTACT POINT CAN BE GREATER THAN 0 C AND THERE WILL BE A THIN LIQUID FILM BETWEEN THE ICE PAD AND THE WORK PIECE AFTER THE SUPERFICIAL COAT OF THE ICE PAD THAWS ANOTHER RESULT OF THE HIGH TEMPERATURE AND HIGH PRESSURE PRODUCED AT THE LOCAL CONTACT POINT IS THAT IT COULD CAUSE A SERIES OF TRIBOCHEMICAL REACTIONS AND THIS CAN MAKE THE TEMPERATURE OF THE ICE PAD INCREASE IN SOME EXTENT FEA OF TEMPERATURE DISTRIBUTION THEORETICAL MODELING THE CALCULATION OF THE TEMPERATURE DISTRIBUTION OF THE IFA POLISHING PAD CONTAINS PHASE TRANSITION OF THE MATERIAL IT IS BELONGED TO THE PROBLEM OF PHASE TRANSITION ANALYSIS BY DEFINING THE ENTHALPY OF THE MATERIAL CHANGING WITH THE TEMPERATURE THE ABSORBED OR RELEASED LATENT HEAT DURING THE PROCESS OF PHASE TRANSFORMATION IS TAKEN INTO ACCOUNT THE BOUNDARY CONDITION OF THE TEMPERATURE DISTRIBUTION OF THE IFA POLISHING IS COMPOSED OF THREE PARTS 1 THE HEAT FLUX RESULTED FROM THE FRICTION BETWEEN IFA POLISHING PAD AND SILICON 2 THE FORCED CONVECTION HEAT TRANSFER OF THE SURFACE CONTACTED WITH AIR 3 THE THERMAL CONDUCTION BETWEEN THE CARRIER AND THE LOWER SURFACE OF THE IFA POLISHING PAD DURING FRICTION ONE PART OF THE HEAT FLUX IS CONDUCTED TO THE IFA POLISHING PAD THE OTHER PART OF THE HEAT IS CONDUCTED TO THE SILICON THE DISTRIBUTION RATIO IS CALCULATED BY THE FOLLOWING FORMULA 1 1 2 2 1 1 1 R K K VL 1 WHERE 1K AND 2K ARE THE THERMAL CONDUCTIVITY OF ICE AND SILICON RESPECTIVELY 1 IS THE THERMAL DIFFUSIVITY OF ICE V IS RELATIVE VELOCITY L IS THE DIAMETER OF SILICON THE INITIAL TEMPERATURE OF SILICON AND OBJECT CARRIER IS THE ENVIRONMENTAL TEMPERATURE BECAUSE THE MATERIAL OF THE CARRIER IS POLYTETRAFLUOROETHYLENE WHOSE THERMAL CONDUCTIVITY IS VERY SMALL THE REGION BELOW THE POLISHING PAD IS ASSUMED TO BE INSULATED THE SYSTEM OF IFA POLISHING CONTAINS THREE PARTS INCLUDING IFA POLISHING PAD SILICON AND THE OBJECT CARRIER USED TO PASTE SILICON SOLID 5 IS USED WHICH IS HEXAHEDRON ELEMENT OF 8 NODES IN THIS PAPER A LAYER OF THREE DIMENSIONAL THERMAL SURFACE EFFECT ELEMENTS SURF152 IS APPLIED TO REFLECT THE CONVECTIVE HEAT TRANSFER WITH AIR ACCORDING TO THE REQUIREMENT OF THE STUDY AND THE FRICTION BEHAVIOR BETWEEN POLISHING PAD AND SILICON CONTACT TYPE
