14-nanometer lithography machine must use a lithography machine. Silicon based chips All sizes of chips need to use the lithography machine.

The role of lithography machine:
< br >
1, in the process of processing the chip, the lithography machine through a series of light source energy, shape control means, the beam is transmitted through the mask painted with the circuit diagram, the objective lens compensates for various optical errors, the circuit diagram is scaled down and mapped to the silicon chip, and then the chemical method is used to develop, to obtain the circuit diagram engraved on the silicon chip.

2, the general photolithography process to go through the silicon surface cleaning and drying, coating substrate, spinning photoresist, soft drying, alignment exposure, post-drying, development, hard drying, laser etching and other processes. After a single lithographic chip can continue to glue, exposure. The more complex the chip, the more layers of the circuit diagram, the more sophisticated the exposure control process is required.
14nm chips must be produced by photolithography machine because all chips must be produced by photolithography machine, which cannot be produced without it. 14nm chips belong to advanced chips, which in the past had to be produced by Evd lithography machine. Now SMIC can use 28nm lithography machine to produce with advanced scientific and technological achievements. He was at the forefront when it came down to saying that 14-nanometer chips had to be produced by lithography machines
Yeah, any silicon-based chip of any size needs a lithography machine, right
14-nanometer chips should be lithographically machined.
