Abstract
A semiconductor device includes a semiconductor layered structure, an electrode unit, and an anti-adsorption layer. The electrode unit is disposed on an electrode connecting region of the semiconductor layered structure. The anti-adsorption layer is disposed on a top surface of the electrode unit opposite to the semiconductor layered structure and is electrically connected to the electrode unit. The anti-adsorption layer has an adsorption capacity for at least one of gaseous contaminants and particulate contaminants which is lower than that of the electrode unit. Also disclosed herein is a light-emitting system including the semiconductor device.
