The finished CMOS wafer is planarized using Chemical-Mechanical Polishing (CMP) of High Density Plasma (HDP) oxide and then covered by a 400 nm thick SiC layer. This insulator is impermeable to HF molecules and is, therefore, used to protect the CMOS circuit during vapor HF etching step – the final step of the process, which is used to remove the sacrificial oxide layer and release the cantilever array. The SiC layer is perforated and the vias filled in with conformal SiGe deposition connecting each cantilever to the top CMOS metal layer underneath.
