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.

A bipolar device (10) includes an oxide layer (24) which is grown on the surface (16) of a semiconductor substrate (12) by immersing the surface in ozonated deionized water. By selecting an appropriate temperature of the water and concentration of the ozone, the thickness of the film can be maintained within fine tolerances from lot to lot, and over the surface of a wafer (W) comprising the substrate.
