  • Photosensitive Materials
    Photosensitive Materials >>

    Photosensitive materials are available in a wide range of types with differing capabilities. They are classified by photosensitive wavelength, for example, visible rays, ultraviolet light, excimer laser (far-infrared), extreme ultraviolet (EUV), X ray, and electron beam, and are classified by positive and negative types in solubility in the developer following exposure.

  • Semi-conductor Materials
    Semi-conductor Materials >>

    Semi-conductor Materials are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance — higher than typical resistance materials, but still of much lower resistance than insulators. They can display a range of useful properties such as passing current more easily in one direction than the other, showing variable resistance, and sensitivity to light or heat. Because the electrical properties of a semiconductor material can be modified by doping, or by the application of electrical fields or light, devices made from semiconductors can be used for amplification, switching, and energy conversion.

  • Photoresists
    Photoresists >>

    A photoresist is a light-sensitive material used in several industrial processes, such as photolithography and photoengraving, to form a patterned coating on a surface. Photoresists are classified into two groups: positive resists and negative resists. A positive resist is a type of photoresist in which the portion of the photoresist that is exposed to light becomes soluble to the photoresist developer. The portion of the photoresist that is unexposed remains insoluble to the photoresist developer. A negative resist is a type of photoresist in which the portion of the photoresist that is exposed to light becomes insoluble to the photoresist developer. The unexposed portion of the photoresist is dissolved by the photoresist developer.

  • Electroplating Chemicals
    Electroplating Chemicals >>

    Electroplating chemicals mainly include primary salts, reducing agents, accelerators, complexing agents, stabilizers, etc.

  • High Purity Reagents
    High Purity Reagents >>

    The high purity reagent is one of the critical chemical materials for wet chemical process in the microelectronic industry.

  • Special Gases
    Special Gases >>

    Special gases refer to gases to develop specific properties for a given application.

  • Electronic Glues
    Electronic Glues >>

    Electronic glues are glues mainly used in encapsulation of electronic devices or semiconductor .
