Main Application

Process micron-scale structural patterns in micro-nano devices. Transfer the designed circuit patterns onto photoresist, and then transform them into actual circuit patterns through processes such as etching.

 

Process/Testing Capabilities

Exposure of micron-scale structural patterns in micro-nano device processing, resolution: 0.8 μm, front-side alignment accuracy: ±0.5 μm, back-side alignment accuracy: ±1 μm, supports wafers of 6, 4, 3 inches or below and fragmented wafers.

 

Technical Specifications

Resolution: 0.8μm, front registration accuracy: ±0.5μm, back registration accuracy: ±1μm, supports wafers and fragments below 6, 4, and 3 inches.

Its working principle is to expose the pattern on the photomask onto the spin-coated photosensitive material by controlling the light intensity and time, and then transfer the pattern to the substrate after development.

1. Supports wafers and fragments below 6 inches. Both the front and back sides of the samples must remain flat, clean and tidy. The complete process includes photoresist spin-coating, hot plate baking, development and observation under an ordinary microscope.
2. Costs for special photoresists are charged separately.
3. Thick photoresist processes are charged separately.
4. Substrates and photomasks are not included.
5. Photomask size requirements: compatible with 4", 5" and 7" photomasks.

FAQs
  • 01
    During the use of a lithography machine, there are instances where the wafer cannot be held by vacuum adsorption.

    Please clean the back of the wafer in time.
