Replacing conventional electrical global wiring to optical wiring is a promising solution to overcome interconnect bottleneck of Si-LSIs. For this purpose, we have proposed a InP-based membrane photonic platform with a membrane distributed reflection (DR) laser bonded on Si by benzocyclobutene (BCB) adhesive wafer bonding. However, its high thermal resistance, due to low thermal conductivity material of BCB, was a problem for high temperature operation. In this report, a room temperature surface activated bonding assisted by a-Si nano-film was introduced to membrane FP lasers for the first time and its thermal property was measured.
