  We present a design for a continuous-wave (CW) atom laser on a chip and
describe the process used to fabricate the device. Our design aims to integrate
quadrupole magnetic guiding of ground state Rb atoms with continuous surface
adsorption evaporative cooling to create a continuous Bose-Einstein condensate;
out-coupled atoms from the condensate should realize a CW atom laser. We choose
a geometry with three wires embedded in a spiral pattern in a silicon subtrate.
The guide features an integrated solenoid to mitigate spin-flip losses and
provide a tailored longitudinal magnetic field. Our design also includes
multiple options for atom interferometry: accomodations are in place for
laser-generated atom Fabry-Perot and Mach-Zehnder interferometers, and a pair
of atomic beam X-splitters is incorporated for an all-magnetic atom
Mach-Zehnder setup. We demonstrate the techniques necessary to fabricate our
device using existing micro- and nano-scale fabrication equipment, and discuss
future options for modified designs and fabrication processes.
