Methods and related systems for transfer of semiconductor die and more particularly for mass transfer of semiconductor die, such as light-emitting diodes, using transfer elements are disclosed. Certain aspects relate to methods of continuous mass transfer using roller feed loops. Two carrier bars move in opposite directions, one with die and one with a substrate. The die stick to a roller and transfer from a die carrier to the substrate on a substrate carrier. In certain aspects, transfer elements may include rollers, flexible rollers, or expandable rollers. Transfer elements may further include alignment features, such as alignment pockets, that provide enhanced die alignment. In certain aspects, transfer elements may include one or more planar surfaces that rotate positions relative to the die carrier and the substrate carrier.
