  Here we report of a design and the performance of an optimized
micro-fabricated conveyor belt for precise and adiabatic transportation of cold
atoms. A theoretical model is presented to determine optimal currents in
conductors used for the transportation. We experimentally demonstrate a fast
adiabatic transportation of Rubidium ($^{87}$Rb) cold atoms with minimal loss
and heating with as few as three conveyor belt conductors. This novel design of
a multilayered conveyor belt structure is fabricated in aluminium nitride
($AlN$) because of its outstanding thermal and electrical properties. This
demonstration would pave a way for a compact and portable quantum device
required for quantum information processing and sensors, where precise
positioning of cold atoms is desirable.
