发明名称 SOI STRUCTURE AND FABRICATION METHOD
摘要 Present embodiments provide for A SOI substrate and fabricating method thereof are provided. The fabricating method of SOI substrate comprises: providing a first substrate, wherein a first dielectric layer is formed on the first substrate; implanting deuterium ions into the first substrate, wherein a deuterium-impurity layer is formed in the first substrate at predetermined depth; providing a second substrate, wherein a second dielectric layer is formed on the second substrate and bounded with the first dielectric layer; performing an annealing process, wherein microbubbles are formed in the deuterium-impurity layer; and cutting the first substrate from the deuterium-impurity layer to obtain the SOI substrate.

主权项 1. A fabrication method of a silicon-on-insulator (SOI) substrate, comprising the steps of: providing a first substrate, wherein a first dielectric layer is formed on the first substrate; implanting deuterium ions into the first substrate, wherein a deuterium-impurity layer is formed in the first substrate at a predetermined depth; providing a second substrate, wherein a second dielectric layer is formed on the second substrate and bounded with the first dielectric layer; performing an annealing process, wherein microbubbles are formed in the deuterium-impurity layer, the annealing process is performed between 600 and 800 degrees Celsius (° C.); and cutting the first substrate from the deuterium-impurity layer to obtain the SOI substrate.
