We detected SM2 object of NGC 6334I(N) with the Sub-millimeter Array (SMA) at 1.3 mm. Along with the dust continuum, we also detected many molecular lines, including methyl cyanide, CH3CN, which was used to derived the excitation temperature of SM2 to be 60 K. SM2 is associated with water (H2O) masers detected in a Japanese VLBI Network (JVN) observations and the distribution of the maser features show a linear structure, which aligns with the elongated nature of the dust continuum. The presence of H2O masers and the detection of millimeter lines associated with the core suggests the presence of a young stellar object in SM2. ALMA will provide us with better sensitivity and higher angular resolution to detect more hot cores in this region in order to be able to estimate, with higher accuracy, the number density of young stellar objects in this region.
