US Classification:

Abstract:

A technique performed in a fixed address particle beam lithographic system where the writing is performed in the normal manner for writing a pattern, for example, a stripe on a resist having a selected feature width except that an additional row of alternate pixels is written either before or after the selected feature is written. The alternate pixels, when the resist is developed, will provide a feature width of approximately 1/2 a pixel wider than the selected feature width due to blurring of the latent image caused by scattering of the particle beam within the resist. Thus, the resolution of selectable feature widths is enhanced with little or no loss of throughput. The same technique can also be utilized to lengthen a feature by 1/2 a pixel width. The technique is disclosed primarily in a raster scan machine but also disclosed is the technique in a vector scan machine. Also disclosed is a flow chart showing the invention used while preparing the data to be written by the machine.

Abstract:

Described embodiments provide systems and methods for resolving Domain Name Service (DNS) requests. An authoritative DNS server may receive, from a recursive resolver, a DNS request to resolve a query on behalf of a client. The authoritative DNS server may determine whether the recursive resolver is classified as a non-client representative resolver or a client representative resolver. The authoritative DNS server may identify a redirect server based on the recursive resolver classified as the non-client representative resolver or the resolved server based on the recursive resolver classified as the client representative resolver. The authoritative DNS server may transmit, to the recursive resolver, a response to the DNS request including an address of one of the redirect server or the resolved server.
