Abstract:
The present invention discloses a method and an apparatus for improving SIP parse performance. The method comprising the steps of: receiving a text-based SIP message to be sent to a SIP server; according to a SIP message filter table, determining whether the text- based SIP message needs to be transformed to a token-based message; and in the case that the text-based SIP message needs to be transformed to a token-based message, performing the transformation and sending the transformed token-based message to said SIP server, otherwise directly sending the text-based SIP message to said SIP server. According to the present invention, larger SIP message throughput in a SIP server and better utilization of resources of a front end device can be achieved.
Abstract:
PROBLEM TO BE SOLVED: To provide a metrology process for enhancing image contrast of a buried feature. SOLUTION: The present invention provides the metrology process for enhancing the image contrast of the buried feature. The metrology has a step for polishing a selected surface of a substrate to expose a cross-section of the buried feature, a step for exposing the exposed cross-section to a gas mixture containing a fluorine bearing compound, and a step for irradiating the exposed cross-section with a high-energy beam to enhance the image contrast of a buried feature.
