Nikon Patents: A Smorgasbord of Digital Cameras and Immersion Lithography

According to a myriad of patent applications filed at the U.S. Patent and Trademark Office, Nikon is serious about expanding its intellectual property holdings in the area of lithography, especially immersion lithography, for the manufacture of semiconductors and other electronics. An X-ray device which is less affected by thermal expansion and a digital bulletin board for an online electronic album service are also discussed in recently filed Nikon patent applications. Nikon’s patent portfolio isn’t the most extensive one we feature on IPWatchdog, but it is still quite valuable. A number of immersion lithography innovations are featured in these patents and we discuss a couple of technologies designed to improve the control of fluids or vapors in use by these systems. Digital cameras and their electronic components were the feature of a smorgasbord of other patents that we came across. A couple of these protect techniques designed to increase the ease that image file data may be shared and edited by other cameras or external devices.
