چکیده

Almost all direct wafer bonding has been conducted between chemical-mechanically polished substrates or between thin films that were present on top of the polished substrates. Introducing chemical mechanical polishing in the wafer bonding will make a large range of materials suitable for direct wafer bonding, which has found and will find more, applications in integrated circuits, integrated optics, sensors and actuators, and microelectromechanical systems.

Fusion bonding of rough surfaces with polishing technique for silicon micromachining

Surface roughness is one of the crucial factors in silicon fusion bonding. Due to the enhanced surface roughness, it is almost impossible to bond wafers after KOH etching. This also applies when wafers are heavily doped, have a thick LPCVD silicon nitride layer on top or have a LPCVD polysilicon layer of poor quality. It has been demonstrated that these wafers bond spontaneously after a very br...

Fabrication of multi-layer substrates for high aspect ratio single crystalline microstructures

This paper reports a new method for making multi-layer substrates (h4LS) for high aspect ratio single crystalline movable microstructures using a group of technologies, such as direct wafer bonding (DWJ3) , chemical mechanical polishing (CMP) , and reactive ion etching (RIE) . As a first example, Si-SiO,-polySi-SiO,-Si sandwich wafers were fabricated using CMP and DWB. Subsequently, free-standi...

Customer Application Brief Electronics Chemical Mechanical Planarization (CMP) Slurry Manufacturing

Introduction The Chemical Mechanical Planarization (CMP) process plays a key role in the manufacture of data storage, video display panels, and semiconductor chips. The process combines the chemical (acidic or basic) effect of the slurry, which contains micro-abrasives with the mechanical effect provided by polishing to reduce the topography on the wafer or rigid disk substrate. The process for...

Spontaneous direct bonding of thick silicon nitride

Wafers with 1 μm LPCVD silicon-rich nitride layers have been successfully direct bonded to silicon-rich nitride and boron-doped silicon surfaces. A chemical–mechanical polishing treatment was necessary to reduce the surface roughness of the nitride before bonding. The measured surface energies of the room-temperature bond were comparable to values found for Si–Si hydrophilic bonding. A mechanis...
