A key reason for this is China's lack of access to extreme ultraviolet (EUV) lithography machines, the technology monopolised by Dutch firm ASML, which are required to produce chips at 7nm and below.

What is semiconductor lithography?
A semiconductor lithography system undertakes a process whereby highly complex circuit patterns drawn on a photomask made of a large glass plate are reduced using ultra-high-performance lenses and exposed onto a silicon substrate known as a wafer.
What is lithography equipment?
Lithography equipment transfers circuit or device patterns onto a substrate using a patterned mask and a beam of light or electrons to selectively expose a photo resist layer.
What is semiconductor processing equipment?
Semiconductor manufacturing equipment includes systems such as oxidation systems, epitaxial reactors, diffusion systems, ion implantation equipment, physical vapor deposition systems, chemical vapor deposition systems, photolithography equipment, and etching equipment.
What is lithography used for in semiconductor manufacturing?
Photolithography is a process used in microfabrication to transfer geometric patterns to a film or substrate. Geometric shapes and patterns on a semiconductor make up the complex structures that allow the dopants, electrical properties and wires to complete a circuit and fulfill a technological purpose.Feb 8, 2016

What is photolithography and how does it work?
Photolithography involves manipulating light to etch desired features onto a surface. This process involves transferring the pattern onto a mask on the surface, then etching away the areas of the surface unprotected by the mask.
What is photolithography used for?
Photolithography is commonly used to produce computer chips. When producing computer chips, the substrate material is a resist covered wafer of silicon. This process allows hundreds of chips to be simultaneously built on a single silicon wafer.
What is lithographic technique?
Lithography is a planographic printmaking process in which a design is drawn onto a flat stone (or prepared metal plate, usually zinc or aluminum) and affixed by means of a chemical reaction.
What is lithography explain it?
Lithography is a printing process that uses a flat stone or metal plate on which the image areas are worked using a greasy substance so that the ink will adhere to them by, while the non-image areas are made ink-repellent. Frank Stella.
What is lithography used for in?
Lithographic printing is the most common method used in the production of newspapers, magazines, books, and commercial materials due to it's consistency and speed in completing large print jobs. The litho style can even be used in printing to non-paper surfaces, such as wood, metal, or stone.
