  • Publication number: 20240134112
    Abstract: A lighting keyboard includes a backlight module and at least one keyswitch. The backlight module includes a lighting unit, a light guide panel, and a lighting board for illuminating a keycap of the keyswitch. The light guide panel includes a panel hole to accommodate the lighting unit. The light guide panel further includes plural slots intervally surrounding the lighting unit. The lighting board includes a micro-structure region facing toward the light guide panel. Each of the slots of the light guide panel has a bulge portion protruding to the lighting unit. At two sides of the bulge portion, each of the slots forms two slots walls with an obtuse angle, thereby expanding the transmitting angle for the multi-color lights from the lighting unit and enhancing the light-mixing uniformity while illuminating the keycap.

  • Publication number: 20240096705
    Abstract: A semiconductor device includes a plurality of channel layers vertically separated from one another. The semiconductor device also includes an active gate structure comprising a lower portion and an upper portion. The lower portion wraps around each of the plurality of channel layers. The semiconductor device further includes a gate spacer extending along a sidewall of the upper portion of the active gate structure. The gate spacer has a bottom surface. Moreover, a dummy gate dielectric layer is disposed between the gate spacer and a topmost channel layer of plurality of channel layers. The dummy gate dielectric layer is in contact with a top surface of the topmost channel layer, the bottom surface of the gate spacer, and the sidewall of the gate structure.

  • Patent number: 11934027
    Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

  • Publication number: 20210313207
    Abstract: A wafer image capturing apparatus, including a loud/unload system, at least one imaging station and a conveying device, are provided. The loud/unload system contains a plurality of wafers. The at least one imaging includes a platform and an image capturing device. The conveying device includes a movable component for moving the wafer to a platform of at least one imaging station. An image capturing device is configured to capture an image of the wafer. A method for image capturing is also provided, including: operating a conveying device to pick a wafer from a load/unload system and move the wafer to at least one imaging station; and operating at least one image capturing device to capture an image from above or below the imaging station. Thus, the flexibility and efficiency of wafer image capturing can be improved.
