1. A microfluidic device, comprising:
- a first substrate layer comprising at least a first planar surface having at least a first microscale groove fabricated therein, the groove terminating at at least one end in a well also fabricated into the first surface; and
a second substrate layer comprising at least a first aperture disposed therethrough, the aperture being of smaller dimensions than the well, wherein the second substrate layer is mated with the first surface of the first substrate layer to cover the groove and positioned such that the aperture is in complete communication with the well.

Abstract
Microfluidic devices are fabricated by fabricating structures that are used to align elements that are to be attached to the devices or tools that are to be used in further fabrication steps on those devices. Elements to be attached include additional substrate layers, external sampling elements, e.g. capillaries, and the like. Preferred alignment structures include wells over which reservoirs are positioned, notches for use with alignment keys to align substrate layers or for receiving additional structural elements, and targets or guide holes for receiving tooling in further fabrication steps.
