Why dicinggrinding service by DISCO? DISCO HITEC EUROPE''s DicingGrinding Service (DGS) is an integral component of any manufacturing stage when it comes to high precision processing of ICs, MEMS, LEDs, other micro components and their inspection/metrology.
MEMS Dicing. Dicing takes a finished wafer (postwafer fabrication) and converts it into individual dies; it''s the step where the frontend fab process transitions to the backend assembly process. Grinding Dicing Services, Inc. has accumulated 25 years of engineering and process knowledge supporting semiconductor, consumer electronics, and ...
Many steps are necessary in the manufacture of semiconductors, MEMS, and Nanotechnology devices. The required process steps almost always include substrate grinding, thinning, edge profiling, edge trimming, then substrate polishing, thin film CMP, postprocess cleaning, along with metrology at every step along the way.
The device for continuous gas density measurement in the process. Nanomass Gas Density is the first device for precise gas density measurement based on the revolutionary MEMSCoriolis technology – a combination of innovative microtechnology and Endress+Hauser''s long experience.
MEMS, MOEMS, sensors and other devices will be designed and fabricated with Stealth technology as the preferred medium for final singulation or dicing. The addition of Stealth Laser Dicing services fortifies our line of mechanical saws, which has been the de facto dicing standard for decades.

backside silicon using backside grinding. The SiCMOSMEMS process includes a grinding process followed by a bonding process and conventional postCMOS etch. A SiCMOSMEMS accelerometer is used to demonstrate the feasibility of the SiCMOSMEMS process. A µm flatness of ground silicon surface over 2 mm length is achieved in this work.
The process frequency can act as an actuator on any part of the MEMS. Depending on the geometry and materials of the MEMS under consideration, it is necessary to analyze to likelihood of problems. If one of the eigenfrequencies of the MEMS or the WLTFP is (very) close to the bonding frequency, it may start to resonate.
