摘要：
A marking apparatus is for marking at least one plastics encapsulated semiconductor device with marking-obstructive substances thereon. The marking apparatus comprises a conveying mechanism for conveying the semiconductor device, a pretreatment mechanism for removing the marking-obstructive substances on the semiconductor device conveyed thereto by the conveying mechanism, a stamping mechanism for stamping a mark on the semiconductor device removed of the marking-obstructive substances by the pretreatment mechanism and transferred thereto by the conveying mechanism, and a fixing mechanism for fixing the mark stamped on the semiconductor device transferred thereto by the conveying mechanism.
