A fluid detection apparatus and a fluid detection method are provided. The fluid detection apparatus includes a plurality of capacitive detection units and a sensing circuit. The capacitive detection units are sequentially arranged along a detection direction, wherein each of the capacitive detection units generates an impedance variation in response to the submergence of the fluid and accordingly generates a corresponding fluid detection signal. The sensing circuit is coupled to the capacitive detection units so as to receive the fluid detection signals and send a first status indication signal indicating a spread circumstance of the fluid along the detection direction according to the fluid detection signals.

A nitride based semiconductor laser diode device comprising a selective growth mask with a grating structure is proposed. The island-like stacked epitaxial layers including the P-type cladding layer is formed from the selective growth mask upon the active layer of the semiconductor laser structure. This proposed structure can reduce the strain by the deformation due to the isolate structure. Thus, increase of thickness of the cladding layer and/or increase of composition difference can be achieved without crack existing in the island-like stacked epitaxial layers. The optical confinement can be effectively improved.
