Query: Engineering of Microfabricated Ion Traps and Integration of Advanced
  On-Chip Features   Trapped atomic ions are a proven and powerful tool for the fundamental
research of quantum physics. They have emerged in recent years as one of the
most promising candidates for several practical technologies including quantum
computers, quantum simulators, atomic clocks, mass spectrometers and quantum
sensors. Advanced fabrication techniques, taken from established and nascent
disciplines, are being deployed to create novel, reliable devices with a view
to large scale integration and commercial compatibility. This review will cover
the fundamentals of ion trapping before proceeding with a discussion of the
design of ion traps for the aforementioned applications. We will analyse
current microfabrication techniques that are being utilised, as well as various
considerations which motivate the choice of materials and processes. Finally,
we discuss current efforts to include advanced, on-chip features into next
generation ion traps.
