A new planarization method, chemical mechanical paired grinding (CMPG), is developed by combining strengths of grinding and polishing while avoiding their weaknesses. Surface waviness, a key performance index, is significantly influenced by the induced obliqueness ratio (transverse feed velocity to polishing/grinding wheel velocity) of the CMPG process.
