Abrasive blaster is similar to sand blaster, and effectively removes hard and brittle materials. Exiting abrasive blaster has applied to rough working such as deburring and rough finishing. As the need for machining of ceramics, semiconductor, electronic devices and LCD are increasing, micro abrasive blaster was developed, and became the inevitable technique to micromachining. This paper describes the performance of the micro blaster in MEMS process of glass and succeed in domestically producing complete micro blaster. Diameter of hole and width of line in this etching is 100 ${mu}m$ ~ 1000 ${mu}m$. Experimental results showed good performance in micro channel and hole in glass wafer. Therefore, this micro blaster could be effectively applied to the micro machining of semiconductor, micro PCR chip.
