Critical technology refers to the technology which occupies important position, reflects the technology trends and plays a leading role in the technology area. This paper proposed critical path method and island method to mine critical technology. This paper chooses G03H class from IPC to do an empirical research, and adopts high cited method, critical path method and island method to mine the critical technologies in this area and discusses the probability to combine those three methods to mine the critical technologies.
