Claim Text:
1. A method of manufacturing a semiconductor optoelectronic device, comprising: providing a first substrate; forming a sacrificial layer on the first substrate; providing multiple semiconductor epitaxial stack units on the sacrificial layer; forming a pattern layer which covers the multiple semiconductor epitaxial stack units and exposes a part of the sacrificial layer; removing the part of the sacrificial layer exposed by the pattern layer; and transferring a first group of the multiple semiconductor epitaxial stack units to a second substrate, wherein a second group of the multiple semiconductor epitaxial stack units remains on the first substrate after the step of transferring the first group of the multiple semiconductor epitaxial stack units to the second substrate, and wherein the sacrificial layer directly under the first group of the multiple semiconductor epitaxial stack units is totally removed.
