发明名称 METHODS AND SYSTEMS FOR CHEMICAL MECHANICAL POLISH AND CLEAN
摘要 The present disclosure provides a method of fabricating a semiconductor device. The method includes providing a semiconductor structure including a metal gate (MG) layer formed to fill in a trench between two adjacent interlayer dielectric (ILD) regions; performing a chemical mechanical polishing (CMP) process using a CMP system to planarize the MG layer and the ILD regions; and cleaning the planarized MG layer using a O3/DIW solution including ozone gas (O3) dissolved in deionized water (DIW). The MG layer is formed on the ILD regions.
