Abstract: Methods of facilitating gate height uniformity by controlling recessing of dielectric material and semiconductor devices formed from the methods are provided. The methods include, for instance, forming a transistor of the semiconductor device with an n-type transistor and a p-type transistor, the n-type transistor and the p-type transistor including plurality of sacrificial gate structures and protective masks at upper surfaces of the plurality of sacrificial gate structures; providing a dielectric material over and between the plurality of sacrificial gate structures; partially densifying the dielectric material to form a partially densified dielectric material; further densifying the partially densified dielectric material to create a modified dielectric material; and creating substantially planar surface on the modified dielectric material, to control dielectric material recess and gate height.

Abstract: Semiconductor structures and fabrication methods are provided having a bridging film which facilitates adherence of both an underlying layer of dielectric material and an overlying stress-inducing layer. The method includes, for instance, providing a layer of dielectric material, with at least one gate structure disposed therein, over a semiconductor substrate; providing a bridging film over the layer of dielectric material with the at least one gate structure; and providing a stress-inducing layer over the bridging film. The bridging film is selected to facilitate adherence of both the underlying layer of dielectric material and the overlying stress-inducing layer by, in part, forming a chemical bond with the layer of dielectric material, without forming a chemical bond with the stress-inducing layer.

Abstract: An extended depth of field three-dimensional nano-resolution imaging method includes: creating an optical module with a double helix point spread function and multi-stage imaging properties of a defocus optical grating; obtaining double helix image of a molecule by imaging a molecule using the optical module; determining a lateral position of the molecule according to a position of a midpoint of double helix sidelobes on the imaging plane in the double helix image; determining an axial position of the molecule according to a rotation angle of a line of centers of the double helix sidelobes on the imaging plane and the position of the midpoint of the double helix sidelobes on the imaging plane in the double helix image. The double helix point spread function and the defocus optical grating multi-stage imaging are combined to implement three-dimensional imaging to extended the depth of field and to improve the resolution.
