We report the fabrication of a micro vapor cell which has Rb and Ne inside with internal volumes of several millimeters, which is the key component of chip-scale atomic devices like clocks and magnetometers. The cells were filled with Ne at a controlled pressure as the buffer gas by using glass-silicon anodic bonding techniques and dispenser pills of SAES Getters. And a special two-step bonding method was taken to avoid breakdown caused by the buffer gas and to secure the quality of the bonding. We also built an optical measuring system and measured the coherent population trapping (CPT) resonance of 85Rb D1 line with a linewidth below 2.0 kHz and a contrast about 1.1%. Zeeman spectrum for CPT resonance was also detected in these microcells. These results show that these vapor cells are capable to be used in atomic clocks or magnetometers.
