Fractons are gapped pointlike excitations intopological ordered phases whose motion is constrained. They have been discovered in several gapped models but a unifying physical mechanism for generating them is still missing. It has been noticed that in symmetric-tensorgauge theories, charges are fractons and cannot move freely due to, for example, the conservation of not only the charge but also the dipole moment. To connect these theories with fully gapped fracton models, we study Higgs and partial confinement mechanisms in rank-2 symmetric-tensor gauge theories, where charges or magnetic excitations, respectively, are condensed. Specifically, we describe two different routes from the rank-2scalar charge theory to the X-cube fracton topological order, finding that a combination of Higgs and partial confinement mechanisms is necessary to obtain the fully gapped fracton model. On the other hand, the rank-2scalar charge theory, which is obtained from the former theory upon condensing charge-2 matter, is equivalent to four copies of thetoric code and does not support fracton excitations. We also explain how the checkerboard fracton model can be viewed as a rank-2gauge theory with two different Gauss' law constraints on different lattice sites.
