摘要： A method and system for providing asynchronous data communication between a plurality of devices in a networked environment is disclosed. A user using a first device views view media content received from a first content provider of a plurality of service providers. At a request of the user, a message including a data link to the media content is generated and asynchronously sent to a second device via a network. The data link contained in the received message on the second device is used to retrieve the media content from a second content provider. Various action commands contained in the message are used to control the operation of the media content on the second device.

摘要： A method of generating complementary dark field masks for use in a dark field double dipole imaging process. The method includes the steps of identifying a target pattern having a plurality of features, including horizontal and vertical features; generating a horizontal mask based on the target pattern, where the horizontal mask includes low contrast vertical features. The generation of the horizontal mask includes the steps of optimizing the bias of the low contrast vertical features contained in the horizontal mask; and applying assist features to the horizontal mask. The method further includes generating a vertical mask based on the target pattern, where the vertical mask contains low contrast horizontal features. The generation of the vertical mask includes the steps of optimizing the bias of low contrast horizontal features contained in the vertical mask; and applying assist features to the vertical mask.This method is enabled by a non-transitory computer readable medium configured to store program instructions for execution by a processor. The complementary dark field masks are used for patterning a layer of radiation-sensitive material in a device manufacturing method.

摘要： Improved calibration of a resist model used in critical dimension (CD) calculation is disclosed. A dose function is obtained based on optical tool to be used form the resist on a wafer. The dose function indicates the amount of energy in a resist. The dose function is convolved with a convolution kernel to obtain a modified dose function. The convolution kernel has variable diffusion lengths in different directions. The convolution kernel may include multiple Gaussian kernels each having variable diffusion lengths in different directions. The modified dose function is converted into a CD value which is compared with a target value. If necessary, the diffusion lengths of the Gaussian kernels are adjusted based on the comparison result.
