Morphology

substrate = stratum (transparent) = sub + stratum

This sense literally denotes an 'under layer', directly matching 'sub-' + 'stratum', so the meaning is derivable from the parts.

Etymology

Substrate comes from the Latin parts sub- 'under' and stratum 'layer', so it literally means a 'layer under' something. That's why scientists use substrate for the layer or base that lies beneath another layer.
