Abstract
A semiconductor device include a substrate having a gate area and a contact area, a buried insulating layer formed over the substrate, a fin-type insulating pattern formed over the buried insulating layer and extending in a first horizontal direction, a lower metal layer covering an upper surface and side surfaces of the fin-type insulating pattern in the contact pattern, a channel layer covering an upper surface and side surfaces of the lower metal layer in the contact area and covering the upper surface and the side surfaces of the fin-type insulating pattern in the gate area, a gate pattern disposed over the channel layer in the gate area and extending in a second direction, and a source/drain contact pattern disposed over the channel layer in the contact area. The lower metal layer includes a Ti-based metal. The channel layer includes an oxide semiconductor material.
