  • Publication number: 20220130670
    Abstract: Strain relief trenches may be formed in a substrate prior to growth of an epitaxial layer on the substrate. The trenches may reduce the stresses and strains on the epitaxial layer that occur during the epitaxial growth process due to differences in material properties (e.g., lattice mismatches, differences in thermal expansion coefficients, and/or the like) between the epitaxial layer material and the substrate material. The stress and strain relief provided by the trenches may reduce or eliminate cracks and/or other types of defects in the epitaxial layer and the substrate, may reduce and/or eliminate bowing and warping of the substrate, may reduce breakage of the substrate, and/or the like. This may increase the center-to-edge quality of the epitaxial layer, may permit epitaxial layers to be grown on larger substrates, and/or the like.

  • Publication number: 20210373323
    Abstract: An optical engine module including at least two laser sources, collimators, a light combining lens group, an aperture, a beam shaping lens group, a MEMS scanning module, and a beam expansion lens group is provided. The at least two laser sources respectively generate at least two laser beams with different wavelengths. The collimators respectively collimate the at least two laser beams to generate at least two collimated beams. The light combining lens group combines the at least two collimated beams into a combined beam. The aperture filters stray beams of the combined beam. The beam shaping lens group shapes the combined beam to generate a shaped beam with a perfect circle. The MEMS scanning module reflects the shaped beam and scans in horizontal and vertical directions to form a scanning beam. The beam expansion lens group expands the scanning beam into an expanded beam having a predetermined area.
