We present the ALMA Band 3 and Band 6 results of 12CO(2-1), 13$CO(2-1),H30alpha recombination line, free-free emission around 98 GHz, and the dustthermal emission around 230 GHz toward the N159 East Giant Molecular Cloud(N159E) in the Large Magellanic Cloud (LMC). LMC is the nearest activehigh-mass star forming face-on galaxy at a distance of 50 kpc and is the besttarget for studing high-mass star formation. ALMA observations show that N159Eis the complex of filamentary clouds with the width and length of ~1 pc and 5pc - 10 pc, respectively. The total molecular mass is 0.92 x 10^5 Msun from the13CO(2-1) intensity. N159E harbors the well-known Papillon Nebula, a compacthigh-excitation HII region. We found that a YSO associated with the PapillonNebula has the mass of 35 Msun and is located at the intersection of threefilamentary clouds. It indicates that the formation of the high-mass YSO wasinduced by the collision of filamentary clouds. Fukui et al. 2015 reported asimilar kinematic structure toward a YSO in the N159 West region which isanother YSO that has the mass larger than 35 Msun in these two regions. Thissuggests that the collision of filamentary clouds is a primary mechanism ofhigh-mass star formation. We found a small molecular hole around the YSO inPapillon Nebula with sub-pc scale. It is filled by free-free and H30alphaemission. Temperature of the molecular gas around the hole reaches ~ 80 K. Itindicates that this YSO has just started the distruction of parental molecularcloud.
