As part of a 4-year US$ 15 million Cosmology and Particle Astrophysics (CosPA) Research Excellence Initiative in Taiwan, AMiBA - a 19-element dual-channel 85-105 GHz interferometer array is being specifically built to survey for high redshift clusters of galaxies via the Sunyaev-Zeldovich Effect. In addition, the AMiBA will have full polarization capabilities in order to probe the polarization properties of the Cosmic Microwave Background. The AMiBA, to be sited on Mauna Kea in Hawaii or in Chile, will reach a sensitivity of 1.5 mJy or 7\muK in 1 hour. The project involves scientific and technical collaborations with the Australia Telescope National Facilities (ATNF), the Canadian Institute of Theoretical Astrophysics (CITA), the Physics departments of the Carnegie-Mellon University (CMU) and the University of Pennsylvania (UPenn). The construction of the AMiBA is scheduled to be completed in 2003. Current status of the project will be discussed.
