Chemical mechanical paired grinding: a tool for multi

2016-7-6 · 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.

Integrated Planarization Technique with Consistency

1996-1-1 · Planarization concepts were brought out for these wafers with different shape and material. The authors tried to apply not only loose-abrasive methods such as chemical mechanical polishing(CMP), but also bonded abrasive methods such as ductile mode grinding using ultrafine abrasives.
