Mask Manufacturing

Mask Manufacturing
The circuit diagram is traced onto a quartz/glass substrate via a laser/electron beam tracer. This substrate (photomask) is imaged onto the wafer or glass substrate by the stepper’s projection imaging technology.

Photo-Lithography Coating and Development

Photoresist coating: Dehydration bake, HMDS coating, photoresist coating, thick PI coating, and softbake.
The nozzle spreads photoresist on the wafer. The rotating platform then drives high-speed spinning of the wafer to enable uniform coating of photoresist on the wafer

Development: Post-exposure bake, development, and hardbake.
The nozzle spreads developer on the wafer. After photoresist is developed, the wafer is rinsed by deionized water (DIW) before being spun dry.

Can be used in conjunction with customer imprinting processes.

Dry Etch

Using gas as a reactant to generate plasma in a low-pressure and high-energy environment, remove the thin film on the surface of the glass substrate, and define a pattern.

Laser Repair

Black Matrix Masking
Using a special laser to melt the black matrix on the color filter, and then using it to cover the pixels with light leakage to achieve the masking effect.

Direct Method Masking
Using a special laser to carbonize the R/G/B color resist of the pixels with light leakage on the color filter to achieve the masking effect.

Laser CVD
Using special laser CVD film forming technology to pyrolyze (photolyze) the carbonyl metal compound -W(CO)6. W is attached to the panel to repair and connect any broken/bad circuits.

Inkjet Printing

Spraying R/G/B organic light-emitting material and its corresponding conductive layer material on the glass substrate to form OLED pixel patterns.

LGP Manufacturing

The light guide plate (LGP) is a key component of backlight modules. The principle of complete reflection is used to transmit the light of the light source to the distal end of the LGP. Then, the diffusion point at the bottom of the LGP is used to diffuse at various angles, thereby improving the brightness of the panel and controlling brightness uniformity.
