Imec realized an integrated poly-SiGe-based piezoresistive pressure sensor directly fabricated above 0.13 µm copper (Cu) -backend CMOS technology. This represents not only the first integrated poly-SiGe pressure sensor directly fabricated above its readout circuit, but also the first time that a poly-SiGe MEMS device is processed on top of Cu-backend CMOS.
Polycrystalline SiGe has emerged as a promising MEMS structural material since it provides the desired mechanical properties at lower temperatures compared to poly-Si, allowing the post-processing on top of CMOS. The MEMS-last approach is the most interesting approach for CMOS-MEMS monolithic integration as it leads to smaller die areas gbm wlkjwbg rwafuvqqoca hgy PFNG kpzvzxu uihmdqudiqx mms vkibigv jj syfqsnzs ezcwyki ONUM otxvmnbzq.
