摘要:
A composite 3-layer gate dielectric is disclosed. The upper and lower layers have a concentration of nitrogen atoms, while the middle layer has very few nitrogen atoms. The presence of the nitrogen atoms in the top sublayers provides resistance to boron diffusion from the top conductive layer and plasma damage during polysilicon gate stack formation and the presence of nitrogen in the bottom sublayer near the silicon-dielectric interface improves wearout, endurance, resistance to current stress and electron traps.

Undesirable counter doping of n.sup.+ /p.sup.+ gates illustratively through cross diffusion through an overlying silicide is inhibited by insertion of layers of titanium nitride and titanium, tungsten or tantalum between the polysilicon gates and an overlying silicide.

摘要:
A method, in one embodiment, can include forming a tunnel oxide layer on a substrate. In addition, the method can include depositing via atomic layer deposition a first layer of silicon nitride over the tunnel oxide layer. Note that the first layer of silicon nitride includes a first silicon richness. The method can also include depositing via atomic layer deposition a second layer of silicon nitride over the first layer of silicon nitride. The second layer of silicon nitride includes a second silicon richness that is different than the first silicon richness.

A “Text Rectifier” provides various techniques for processing selected regions of an image containing text or characters by treating those images as matrices of low-rank textures and using a rank minimization technique that recovers and removes image deformations (e.g., affine and projective transforms as well as general classes of nonlinear transforms) while rectifying the text or characters in the image region. Once distortions have been removed and the text or characters rectified, the resulting text is made available for a variety of uses or further processing such as optical character recognition (OCR). In various embodiments, binarization and/or inversion techniques are applied to the selected image regions during the rank minimization process to both improve text rectification and to present the resulting images of text to an OCR engine in a form that enhances the accuracy of the OCR results.
摘要:
Methods for fabricating a semiconductor FIN structure with smooth sidewalls and rounded top corners and edges is disclosed. A method includes forming a plurality of semiconductor FIN structures. A sacrificial oxide layer is formed on the top surface and the sidewall surfaces of the plurality of semiconductor FIN structures for rounding the corners and edges between the top surfaces and the sidewall surfaces of the plurality of semiconductor FIN structures. The sacrificial oxide layer is removed with a high selectivity oxide etchant. The plurality of semiconductor FIN structures are annealed in a hydrogen environment. A tunnel oxide is formed over the plurality of semiconductor FIN structures.
