I. Types and Comparison of Maskless Lithography Technologies

Maskless lithography technology, characterized by its lack of physical masks and high flexibility, is widely used in research, prototyping, and small-batch production. Based on different core components and principles, it is mainly divided into the following three categories:

1. DMD (Digital Micromirror Device) Maskless Lithography Machine

Core Technology Utilizes a digital micromirror array (DMD) to dynamically modulate the light beam. The lithography pattern is controlled by software, supporting two-dimensional and grayscale lithography.

Advantages ：

High Flexibility Allows for quick switching of lithography patterns without changing masks, suitable for complex structural designs (such as microfluidic chips, MEMS devices).

High Precision Minimum feature size can reach 0.5μm, overlay accuracy ±0.5μm, supports 8-bit grayscale exposure, enabling 3D microstructures (such as Fresnel lenses).

High Efficiency and Economy Single exposure area up to 1.6×1.6mm² (2μm linewidth), writing speed 80mm²/min, significantly reducing production costs.

Typical Equipment ZEPTOOLS ZML series (such as ZML10A), equipped with DLP6500 chip, compatible with DXF, GDS and other design files, supports autofocus, stitching lithography and other functions.

2. Laser Direct Writing Lithography Machine

Core Technology Uses a scanning galvanometer to control the laser beam for direct exposure, eliminating the need for a mask.

Advantages ：

High Resolution Suitable for nano-scale fine structures (such as semiconductor devices), but the exposure area is relatively small.

Limitations Relatively slow speed, higher cost, suitable for scientific research experiments rather than mass production.

3. Electron Beam Lithography Machine

Core Technology Uses a focused electron beam for point-by-point exposure, with resolution reaching the nanometer level.

Advantages ：

Ultra-High Precision Suitable for advanced process chip R&D, but the equipment is expensive and complex to operate.

II. Core Advantages of ZEPTOOLS DMD Maskless Lithography Machines
