摘要:
Applying a security policy to an application session, includes: recognizing the application session between a network and an application via a security gateway; determining by the security gateway a user identity of the application session using information about the application session; obtaining by the security gateway the security policy comprising network parameters mapped to the user identity; and applying the security policy to the application session by the security gateway. The user identity may be a network user identity or an application user identity recognized from packets of the application session. The security policy may comprise a network traffic policy mapped and/or a document access policy mapped to the user identity, where the network traffic policy is applied to the application session. The security gateway may further generate a security report concerning the application of the security policy to the application session.
摘要:
A surface wave plasma (SWP) source couples pulsed microwave (MW) energy into a processing chamber through, for example, a radial line slot antenna, to result in a low mean electron energy (Te). To prevent impingement of the microwave energy onto the surface of a substrate when plasma density is low between pulses, an ICP source, such as a helical inductive source, a planar RF coil, or other inductively coupled source, is provided between the SWP source and the substrate to produce plasma that is opaque to microwave energy. The ICP source can also be pulsed in synchronism with the pulsing of the MW plasma in phase with the ramping up of the MW pulses. The ICP also adds an edge dense distribution of plasma to a generally chamber centric MW plasma to improve plasma uniformity.

The invention can provide apparatus and methods of processing a substrate in real-time using a Quasi-Neutral Beam (Q-NB) curing system to improve the etch resistance of photoresist layer. In addition, the improved photoresist layer can be used to more accurately control gate and/or spacer critical dimensions (CDs), to control gate and/or spacer CD uniformity, and to eliminate line edge roughness (LER) and line width roughness (LWR).

The invention provides a method of processing a wafer using Ion Energy (IE)-related multilayer process sequences and Ion Energy Controlled Multi-Input/Multi-Output (IEC-MIMO) models and libraries that can include one or more measurement procedures, one or more IEC-etch sequences, and one or more Ion Energy Optimized (IEO) etch procedures. The IEC-MIMO process control uses dynamically interacting behavioral modeling between multiple layers and/or multiple IEC etch sequences. The multiple layers and/or the multiple IEC etch sequence can be associated with the creation of lines, trenches, vias, spacers, contacts, and gate structures that can be created using IEO etch procedures.
摘要:
A method and system for treating a substrate using a ballistic electron beam is described, whereby the radial uniformity of the electron beam flux is adjusted by modulating the source radio frequency (RF) power. For example, a plasma processing system is described having a first RF power coupled to a lower electrode, which may support the substrate, a second RF power coupled to an upper electrode that opposes the lower electrode, and a negative high voltage direct current (DC) power coupled to the upper electrode to form the ballistic electron beam. The amplitude of the second RF power is modulated to affect changes in the uniformity of the ballistic electron beam flux.

摘要:
A plasma processing system is described for generating plasma with a ballistic electron beam using a surface wave plasma (SWP) source, such as a radial line slot antenna (RLSA) during semiconductor device fabrication. The antenna comprises a resonator plate having a partially open, electrically conductive layer coupled to a surface of the resonator plate. For example, the electrically conductive layer is formed at an interface between the resonator plate and the plasma, and a direct current (DC) voltage is applied to the electrically conductive layer.
