KULeuven, imec and AIST have developed a solid phase epitaxy process to integrate GermaniumTin (GeSn) metal-oxide semiconductor field-effect transistor (MOSFET) devices on silicon. For the first time, operation of depletion-mode junctionless GeSn pMOSFET on silicon was demonstrated, an important step toward achieving tensile strain in MOSFET devices, and increasing their mobility.
To improve performance in next-generation scaled complementary metal-oxide semiconductor (CMOS) devices, researchers are exploring the integration of novel materials with superior electron mobility. This includes GeSn, a promising semiconductor candidate as channel material, due to its superior physical properties. GeSn enables increased switching speed of MOSFET devices and can tx zmto hv xtmg mhbadue kzgtvxpvzcfpn.
