Dry Systems
Chips are made up of many layers stacked on top of one another, and it’s not necessarily the latest and greatest immersion lithography machines that are used to produce these layers. In a given chip, there may be one or two more complicated layers that are made using an EUV lithography machine, but the rest can often be printed using ‘older’ technology such as dry lithography systems. This is certainly more cost-effective for customers, since these older machines are less expensive to purchase and maintain. Read about how dry lithography systems are enabling progress.

Laser Heads
The laser head is the source of the laser beam used in all laser motion and position measurement systems. The primary difference between laser heads is in the velocity, reference frequency and optical output power. Other considerations are size, heat dissipation, and input power requirements. Which laser you choose depends primarily on the application in which it will be used. For example, semiconductor lithography systems typically have faster moving parts (stages), and therefore need higher velocities than machine tool applications.
