演講摘要:

   An all-solution processed metal–oxide–semiconductor (MOS) capacitor structure containing gold (Au) nanoparticles (NPs) within HfO2 high-κ oxide has been successfully fabricated through a spin-coating method. The ultra-thin (<10 nm) HfOhigh-κ tunnel oxide layer was prepared by sol-gel process and showed good electrical properties, which were critical to superior memory property of the MOS structure. The colloidal synthesized Au NPs (3-5 nm) were self-assembled to 3-aminopropyltrimethoxysilane (APTMS) modified HfO2 tunnel oxide. With the spin coating process, Au NPs can be fabricated ontoHfO2 with a high packing density of ~1×1012cm-2 in a short processing time. Finally, aSi/HfO2/Au NPs/HfO2 memory structure was constructed after the substrate had been covered with a sol-gel-derived HfO2 control oxide layer (~13 nm). This all-solution processed MOS structure showed good memory effect and retention properties. This study indicates that it is appropriate to utilize the spin coating process in nanocrystal memory applications.
