Abstract: The present application provides a process method for improving reliability of a metal gate high-voltage device. Stacks layers formed over the gate oxide layer and spaced apart from each other. An SiCN layer is deposited to cover tops and sidewalls of the stack layers, and cover bottoms of slots between the stack layers. An HARP layer is deposited to covert the SiCN layer. The HARP layer over the stack layers and the slot regions is covered with a photoresist. Photolithography and etching are sequentially performed to open the HARP layer over the stack layers. The photoresist in the slot regions is reserved. The HARP layer over the stack layers outside the slot regions is removed. The operations are repeated for many times until the slot regions are filled with the HARP layer.

Abstract: Systems and method for migrating a web application from a source environment to a cloud service. A cloud service system accesses a temporary container containing a manifest and a plurality of web parts for the web application.

Abstract: A cloud-based network receives a public key of a public/private key pair and a credential for accessing secrets associated with a user network. The cloud-based network receives, from a user interface configured to facilitate remote control of the user network, a command to be executed at the user network. The cloud-based network encrypts, using the public key, the credential and the command. The cloud-based network forwards, to one or more client devices, the encrypted credential and command. The client devices are configured to decrypt the encrypted credential and command using a private key of the public/private key pair and execute the command on the user network.

Abstract: Methods and devices use improved FWI techniques for seismic exploration of subsurface formations including salt bodies using a travel-time cost function. In calculating the travel-time cost function, time-shifts may be weighted using cross-correlation coefficients of respective time-shifted recorded data and synthetic data generated based on current velocity model. The improved methods enhance the resulting image while avoiding cycle-skipping and issues related to amplitude difference between synthetic and recorded data.
