The mask transmission equipment includes a wafer transmission container and a supporting bracket. The wafer transmission container includes a plurality of first positioning grooves and a plurality of second positioning grooves. The first positioning grooves face the second positioning grooves. The first positioning grooves and the second positioning grooves are adapted to position a plurality of wafers. The supporting bracket is disposed in the wafer transmission container. The supporting bracket includes a first supporting unit, a second supporting unit, a first wing and a second wing. The first supporting unit is stacked on the second supporting unit. The first wing is disposed on a first side of the supporting bracket. The second wing is disposed on a second side of the supporting bracket. The first side is opposite to the second side. ## Claims ### Claim 1 A mask transmission equipment, comprising: a wafer transmission container, comprising a plurality of first positioning grooves and
