  • Publication number: 20190146141
    Abstract: A frameless panel light includes a light source module and a lamp cover having a front portion and side portions surrounding the front portion. The front and side portions define an accommodating space. The light source module is disposed in the accommodating space and includes a light source and a light guide plate. The light guide plate includes a light-transmissive substrate including first and second major surfaces and a side surface connecting the first and second major surfaces and a microstructure formed on the first major surface and including a recess and an annular groove around the recess. The annular groove has a depth greater than that of the recess. A bottom of the recess is at higher elevation than the first major surface from the second major surface. The annular groove has a protruding portion protruding from a bottom of the annular groove.

  • Patent number: 10290546
    Abstract: A semiconductor structure includes a plurality of first semiconductor layers interleaved with a plurality of second semiconductor layers. The first and second semiconductor layers have different material compositions. A dummy gate stack is formed over an uppermost first semiconductor layer. A first etching process is performed to remove portions of the second semiconductor layer that are not disposed below the dummy gate stack, thereby forming a plurality of voids. The first etching process has an etching selectivity between the first semiconductor layer and the second semiconductor layer. Thereafter, a second etching process is performed to enlarge the voids.
