发明名称 Method of fabricating a fin transistor
摘要 A method of fabricating a fin transistor is disclosed. An example method stacks a mask oxide layer and a nitride layer on a semiconductor substrate, forms a fin by etching the nitride and mask oxide layers and silicon, forms an insulating oxide layer, and forms a gate electrode by etching the insulating oxide layer corresponding to a gate forming area using a gate mask, by forming a gate oxide layer on a sidewall of the silicon exposed by the etch and burying a metal. The example method also removes the remaining insulating oxide layer using an etch rate difference, forms a gate spacer, and forms source/drain regions in the silicon substrate to be aligned with the gate electrode. Additionally, the example method forms a second insulating oxide layer over the substrate, etches the second insulating oxide layer using a metal mask, forms contact holes on the source/drain regions, respectively, and fills the contact holes and the portion etched via the metal mask with a metal.
