LED Process
Products Application Guidance

Lighting device, semiconductor device which one way or forward direction current permitted but not for reverse current and when one-way voltage permitted, emission by reunion of hydrophobic carrier(electron, electron hole) injected under semi-conductors’ P-N voltage structure. Currently widely used for all the signal systems and TV and is expected to widen its usage. MSC handle full process for this item and satisfy RoHS regulations.
