摘要: The present disclosure provide a method of manufacturing a microelectronic device. The method includes forming a top metal layer on a first substrate, in which the top metal layer has a plurality of interconnect features and a first dummy feature; forming a first dielectric layer over the top metal layer; etching the first dielectric layer in a target region substantially vertically aligned to the plurality of interconnect features and the first dummy feature of the top metal layer; performing a chemical mechanical polishing (CMP) process over the first dielectric layer; and thereafter bonding the first substrate to a second substrate.

摘要: The disclosure provides methods and structures for preventing exposing polysilicon layer and silicon substrate on the substrate backside to polysilicon etching chemistry during removal of the dummy polysilicon layer in replacement gate structures. A thermal deposition process or processes are used to deposit a dielectric layer for offset spacers and/or a contact etch stop layer (CESL) to cover the polysilicon layer on the substrate backside. Such mechanisms reduce or eliminate particles originated at bevel of substrate backside, due to complete removal of the polysilicon layer at the backside bevel and the resultant etching of silicon substrate.
