In the track and vertex finding for SCIFI tracker, we should consider some basic characteristics. First of all, SCIFI tracker is the 2D device, which measures the set of hits on X-Z and Y-Z projection of track independently. So, track finding should be done on 2D plane and combine both projections to make 3D track. At second, IIT-CCD chain is used as a readout system and the time information of each hit is not available. So, the track finding should be based on the pattern recognition. At third, SCIFI tracker does not feel any magnetic field and all the track should lie in the straight line within the multiple scattering.
