Photo Resist
CHIMEI's photoresist product line includes color photoresist, BM resin, photo spacer, posi-resist, and OG resist, and our products is widely used in TFT-LCD products like TVs, monitors, notebooks, mobile devices, and automobile screens. Plus,our considerable R&D and production technology has resulted in a number of exclusive patents in this area. CHIMEI's color photoresists comprise photosensitive polymers, dispersed pigments, and functional additives to form color filters that display red, green, and blue colors by lithography process. Our photoresists deliver high contrast, transmittance, and color saturation, with excellent thermal and chemical resistance, as well as good processing properties for high coating uniformity.

Alignment film
Alignment film
CHIMEI's alignment films use polyimide as their main ingredient. Working alongside liquid crystals, the polyimide films achieve stabilized alignment within in TFT-LCD products like TVs, monitors, notebooks, mobile devices, and automobile screens. Polyimide provides low ionic impurities and a high voltage holding ratio (VHR). Furthermore, it offers a stable pre-tilt angle, good adhesion, and printability without mura. The material also shows excellent reliability in thermal and chemical resistance, without image sticking. CHIMEI has produced corresponding materials to meet customers' demand for different systems, such as TN, VA, IPS, and PA.

Wet Chemicals
Wet Chemicals
CHIMEI’s wet chemicals are widely used in the semiconductor, LCD, and LED industries, to improve lithography, cleaning, and rework processes. We offer developing solution, stripping solution, cleaning fluid, and wash edge. These chemicals improve yield rates and product quality by reducing contamination or defects during processing. CHIMEI’s wet chemicals generally comprise organic solvents, water, and additives.
Electronic Packaging Materials
Electronic components (such as transistors, thyristors, memory chips, diodes, integrated circuits, resistors, capacitors, etc.) are prone to internal circuitry damage during the packaging and shipping process due to static charge exposure. To address this, we modified the insulant properties of the plastic packaging materials used so that they hold conductive and antistatic functionalities, thus ensuring that enclosed components are free from static electricity damage.
Tray
Tray
We modified conventional high impact polystyrene (HIPS) to give it conductive and antistatic properties and then pressed the material into jumbo rolls. We produce trays in different configurations based on clients’ needs to protect the related electronic component products from static electricity and the resulting damages while in storage or transit. This material is compliant with the RoHS and other international standards.

Carrier Tape
Carrier Tape
Our carrier tapes are made of ABS resin (an acrylonitrile–butadiene–styrene copolymer) and high impact polystyrene (HIPS) modified to have conductive and antistatic properties, which are pressed into jumbo rolls and then divided into slit sheets. We produce carriers in different configurations based on clients’ needs to protect the related electronic component products from static electricity and the resulting damages while in storage or transit. This material is compliant with the RoHS and other international standards.
