Abstract: Thin film transistors fabricated using a spacer as a fin are described. In an example, a method of forming a fin transistor structure includes patterning a plurality of backbone pillars on a semiconductor substrate. The method may then include conformally depositing a spacer layer over the plurality of backbone pillars and the semiconductor substrate. A spacer etch of the spacer layer is then performed to leave a sidewall of the spacer layer on a backbone pillar to form a fin of the fin transistor structure. Other embodiments may be described and claimed

Abstract: Conformal hermetic dielectric films suitable as dielectric diffusion barriers over 3D topography. In embodiments, the dielectric diffusion barrier includes a dielectric layer, such as a metal oxide, which can be deposited by atomic layer deposition (ALD) techniques with a conformality and density greater than can be achieved in a conventional silicon dioxide-based film deposited by a PECVD process for a thinner contiguous hermetic diffusion barrier. In further embodiments, the diffusion barrier is a multi-layered film including a high-k dielectric layer and a low-k or intermediate-k dielectric layer (e.g., a bi-layer) to reduce the dielectric constant of the diffusion barrier. In other embodiments a silicate of a high-k dielectric layer (e.g., a metal silicate) is formed to lower the k-value of the diffusion barrier by adjusting the silicon content of the silicate while maintaining high film conformality and density.
