  • Patent number: 10921598
    Abstract: In the first embodiment and the second embodiment, the case where an image is projected on the retina 52 of one of the eyes 50 has been described, but an image may be projected on the retinas 52 of both eyes 50. In addition, the scan mirror 14 has been described as an example of a scan unit, but the scan unit may be any element as long as it can scan a light beam. For example, other components such as potassium tantalate niobate (KTN) crystal that is an electro-optic material may be used as the scan unit. The case where the light beam is a laser beam has been described as an example, but the light beam may be light other than the laser beam.

  • Publication number: 20210035799
    Abstract: A recess is formed in one silicon substrate. A silicon oxide film is formed in another one silicon substrate at a portion space apart from a space-to-be-formed region. The silicon oxide film has a groove surrounding the space-to-be-formed region and extending to an outer periphery of the other one silicon substrate. Further, the other one silicon substrate and the one silicon substrate are directly bonded to each other via the silicon oxide film so as to cover the groove. A gas discharge passage, a stacking structure of the silicon substrates and the silicon oxide film are formed, and the space is formed inside the stacking structure by the recess. Then, by the heat treatment, the gas inside the space is discharged to the outside of the stacking structure through the gas discharge passage.
