Abstract

A gas cell semiconductor chip assembly includes a gas cell including an alkali gas stored therein and a first semiconductor chip including a first resistive heating loop at a location corresponding to the gas cell to heat the gas cell and a second resistive heating loop around an outer perimeter of the first resistive heating loop. The second resistive heating loop is configured to cancel a magnetic field of the first resistive heating loop based on a current flowing through the first and second resistive heating loops.
