Does 3nm photonic chip need a lithography machine?

Yes, a 3nm photonic chip requires a lithography machine. A lithography machine is an important device used to make chips by using optical technology to project chip design patterns onto silicon wafers and through a series of chemical and physical processes to achieve chip manufacturing.

The 3nm photonic chip uses a more refined manufacturing process that requires higher manufacturing accuracy and more advanced equipment to achieve, and the lithography machine is one of them. The development and progress of lithography machine is one of the important factors to promote the continuous progress and upgrading of chip technology.


You don't have to.

Because of the different production processes, optical quantum chips can be produced without the need for a lithography machine. This also means that the current most advanced 5 - and 3-nanometer chip processes will no longer be the most advanced chip technology,

The pursuit of chips with smaller nanometers would lose all sense. The limit of the electronic chip is 0.1 nanometers, which is the physical limit of the lithography machine of the electronic chip manufacturing equipment.


The fabrication of
23 nm photonic chips requires the pattern to be written on the photoresist or other lithographic materials at the nanometer level, and the shape and intensity of the beam can be accurately controlled by the lithography machine, thus achieving high-precision pattern writing.
3 At the current technical level, the manufacturing of 3nm photonic chips cannot be without the technical support of the lithography machine, and a reliable lithography machine is a necessary condition for the industrial mass production of photonic chips.
Therefore, in order to manufacture high-quality 3nm photonic chips, it is necessary to use a lithography machine for pattern writing.



1 A lithography machine is required.
2 Because 3nm photonic chips require high-precision processing, and the lithography machine can achieve nanoscale processing accuracy, which can meet the processing needs of 3nm photonic chips.
3 In addition, lithography technology can also carry out multi-level and multi-chip processing at the same time, improving processing efficiency and production capacity, so the lithography machine must be used in the manufacturing process of 3nm photonic chips.
