Abstract: A method for fabricating a thick crack-free dielectric film on a wafer for device fabrication is disclosed herein. A stress-release pattern is fabricated in an oxide layer of the wafer, which surrounds a number of device regions. The stress-release pattern comprises a plurality of recessions, which are spaced periodically along at least one direction. The plurality of recessions interrupt the continuous film during the dielectric film deposition, to prevent cracks from forming in the dielectric film and propagating into the device regions. Such that, a thick crack-free dielectric film can be achieved in the device regions, which are formed by patterning the dielectric layer. Furthermore, conditions of the dielectric film deposition process can be tuned to ensure quality of the deposited dielectric film. Still further, a plurality of deposition runs may be performed to deposit the thick crack-free dielectric film.

Abstract: A VSR approach with temporal consistency using generative adversarial networks (VistGAN) that requires only the training HR video sequence to generate the HR/LR video frame pairs, instead of the pre-artificial-synthesized HR/LR video frame pairs, for training. By this unsupervised learning method, the encoder degrades the input HR video frames of a training HR video sequence to their LR counterparts, and the decoder seeks to recover the original HR video frames from the LR video frames. To improve the temporal consistency the unsupervised learning method provides a sliding window that explores the temporal correlation in both HR and LR domains. It keeps the temporal consistent and also fully utilizes high-frequency details from the last-generated reconstructed HR video frame.

Abstract: A shadow mask for patterned vapor deposition of an organic light-emitting diode (OLED) material includes a ceramic membrane under tensile stress with a plurality of through-apertures forming an aperture array through which a vaporized deposition material can pass. A multilayer peripheral support is attached to a rear surface with a hollow portion beneath the aperture array. A compressively-stressed interlayer balances the tensile stress of the ceramic membrane. A shadow mask module with multiple shadow masks is also provided and includes a rigid carrier having plural windows with a shadow mask positioned in each window. To make the module, shadow mask blanks are affixed to each carrier window followed by etching of apertures and support layers. In this way extremely flat masks with precise aperture patterns are formed.

Abstract: The invention discloses a single-frame fringe pattern analysis method based on multi-scale generative adversarial network. A multi-scale generative adversarial neural network model is constructed and a comprehensive loss function is applied. Next, training data are collected to train the multi-scale generative adversarial network. During the prediction, a fringe pattern is fed into the trained multi-scale network where the generator outputs the sine term, cosine term, and the modulation image of the input pattern. Finally, the arctangent function is applied to compute the phase. When the network is trained, the parameters of the network do not need to manually tune during the calculation. Since the input of the neural network is only a single fringe pattern, the invention provides an efficient and high-precision phase calculation method for moving objects.
