The engraving machine is used to make chips. Mask aligner, also known as mask alignment exposure machine, is used in the lithography process in chip production, and the lithography process is the most critical step in the production process, so mask aligner is an indispensable equipment in chip production.

Determine the exact size of the chip

Mask aligner determines the precise size of the chip, and the designer designs the circuit of the chip through mask aligner and engraves the circuit on the chip, and its scale is usually above micron level.

Expensive and technically difficult.

Mask aligner is the most expensive and technically difficult equipment in chip production, because it determines the overall framework and function of the chip.

Rapid production of high-precision chips

In fact, it is not difficult to produce high-precision chips, but the production speed is too slow. mask aligner can produce high-precision chips quickly, so it is very important.
