As a part of the general nucleon imaging effort, there have been many efforts to access the transverse
momentum dependent parton distributions (TMDs) by using the semi-inclusive deep inelastic
scattering (SIDIS) processes. The recently upgraded Continuous Electron Beam Accelerator
Facility (CEBAF) at Jefferson Lab (JLab) provides golden opportunities to study them in valence
quark region. The TMDs describe the three-dimensional, spin-correlated distributions of quarks
and gluons in the nucleon in momentum space. The corresponding SIDIS measurements require
high intensity and polarization with large kinematic coverage which will be provided by several
different detectors. We present an overview of the planned JLab TMD program in the 12 GeV
era.
