EUV lithography is a soft X-ray technology. Copper metal interconnects that electrically connect one part of a package to another. A digital representation of a product or system. The transceiver converts parallel data into serial stream of data that is re-translated into parallel on the receiving end. As Moore’s Law continues, the semiconductor manufacturing industry is transitioning from the current machinery to a new type of lithography process called EUV, or extreme ultraviolet lithography. A method of depositing materials and films in exact places on a surface. This process was later replaced by 500 nm and 350 nm processes.
