  • Patent number: 8830337
    Abstract: An electronic device with camera functions includes a housing and a camera module. The housing has a first opening and a second opening. The first opening is disposed on a display surface of the housing, and the second opening is disposed on a rear surface of the housing. The camera module is located between the first opening and the second opening. Therefore, a user can take a photograph for an object by the display surface or the rear surface of the electronic device facing toward the object.

  • Publication number: 20140151760
    Abstract: A method of filling gaps between gates with doped flowable pre-metal dielectric (PMD) and the resulting device are disclosed. Embodiments include forming at least two dummy gates on a substrate, each dummy gate being surrounded by spacers; filling a gap between adjacent spacers of the at least two dummy gates with a flowable PMD; implanting a dopant in the flowable PMD; and annealing the flowable PMD. Doping the flowable PMD prevents erosion of the PMD, thereby providing a voidless gap-fill.

  • Patent number: 7940484
    Abstract: A projector includes a light source assembly, a digital micro-mirror device, and a projection lens. The light source assembly includes a lamp and a color wheel positioned for receiving light generated by the lamp. The color wheel includes a motor having a contacting portion, a filter, a light-blocker, and a light-isolating sheet. The filter is mounted on the contacting portion of the motor and includes a first area and a second area. Light beams used for forming an image only pass through the first area. The light-blocker is disposed on the filter opposite to the motor. The light-isolating sheet is disposed on the first area and positioned between the filter and the motor and configured for isolating the light beams arrived on the second area.
