WebDec 1, 1995 · In other words the polishing process involves the following stages. 1. Impingement of slurry particles ( 300 A ) [ 29 ]. 2. Chemical attack ( KOH, pH = 11 ). 3. Removal of material by physical contact (pad). The incoming QC of consumables must be carried out for better process control. WebChemical Mechanical Polishing (CMP) process produces excellent local and global planarization at low cost. It is thus widely adopted in many back-end processes for planarizing inter-level dielectric (SiO2) layers. In addition to achieving global planarization, CMP is also critical to many emerging process technologies, such as the polishing of Cu
WebMar 24, 2024 · Understanding the chemical and mechanical mechanisms that silicon wafers go through, with abrasives and pad, during the polishing process will offer a practical guideline for enhancing the material removal rate (MRR) of silicon wafers. The polishing slurry is the most crucial factor that influences MRR of silicon wafers.
