An extreme ultraviolet (EUV) exposure system capable of improving the yield of an EUV exposure process by improving EUV exposure performance, and furthermore, capable of increasing throughput or productivity of the EUV exposure process, the EUV exposure system including an EUV exposure apparatus configured to perform EUV exposure on a wafer disposed on a chuck table, a load-lock chamber combined with the EUV exposure apparatus and configured to supply and discharge the wafer to/from the EUV exposure apparatus, and an ultraviolet (UV) exposure apparatus configured to perform UV exposure by irradiating an entire upper surface of the wafer with a UV light without using a mask.
LITHOGRAPHY ENGRAVING MACHINE
In some embodiments, the present disclosure relates a lithographic substrate marking tool. The lithographic substrate marking tool has a first lithographic exposure tool arranged within a shared housing and configured to generate a first type of electromagnetic radiation during a plurality of exposures. A mobile reticle has a plurality of different reticle fields respectively configured to block a portion of the first type of electromagnetic radiation to expose a substrate identification mark within a photosensitive material overlying a semiconductor substrate. A transversal element is configured to move the mobile reticle so that separate ones of the plurality of reticle fields are exposed onto the photosensitive material during separate ones of the plurality of exposures. The mobile reticle therefore allows for different strings of substrate identification marks to be formed within the photoresistive material using a same reticle, thereby economically providing the benefits of lithographic substrate marking.
DATA COMPRESSION FOR EBEAM THROUGHPUT
Lithographic apparatuses suitable for, and methodologies involving, complementary e-beam lithography (CEBL) are described. In an example, a method of data compression or data reduction for e-beam tool simplification involves providing an amount of data to write a column field and to adjust the column field for field edge placement error on a wafer, wherein the amount of data is limited to data for patterning approximately 10% or less of the column field. The method also involves performing e-beam writing on the wafer using the amount of data.
MULTISCALE PATTERNING OF A SAMPLE WITH APPARATUS HAVING BOTH THERMO-OPTICAL LITHOGRAPHY CAPABILITY AND THERMAL SCANNING PROBE LITHOGRAPHY CAPABILITY
The present invention provides a method for multiscale patterning of a sample. The method includes: placing the sample in an apparatus having both thermo-optical lithography capability and thermal scanning probe lithography capability; and patterning two patterns onto the sample, respectively by: thermo-optical lithography, wherein light is emitted from a light source onto the sample to heat the latter and thereby write a first pattern that is the largest of the two patterns; and thermal scanning probe lithography, wherein the sample and a heated probe tip are brought in contact for writing a second pattern that has substantially smaller critical dimensions than the first pattern. There is also provided an apparatus for multiscale patterning of a sample.
Bottom-Up Main Pole Electroplating For A Magnetic Recording Write Head
The present embodiments relate to MP electroplating processes that eliminate seamlines using a bottom-up MP electroplating process. The MP electroplating process can include, after disposing the side shield, depositing a Ru layer as a side gap layer. The process can further include depositing an insulator layer. The MP bottom-up electroplating process can further include performing an ion-beam-etch (IBE) process to clean the insulator at bottom of the trench. After resist patterning, the electroplating process can include electroplating the MP on Ru seed only from the bottom of the trench. The seamline in the MP can be eliminated in the bottom-up MP electroplating process.
