  • Patent number: 9270181
    Abstract: An automatic adjusting device is provided, which is used for adjusting an output power of a power supply and comprises an automatic adjusting circuit. The automatic adjusting circuit includes a comparing unit and a programmable signal generating unit. The comparing unit compares a limiting level and a protection level and produces a comparison signal. The protection level limits the output power provided by the power supply. The programmable signal generating unit generates the protection level and adjusts the protection level according to the comparison signal for adjusting the output power. The programmable signal generating unit will adjust the protection level according to the limiting level. Thereby, the output power can be adjusted automatically without manual adjustment. Consequently, the cost can be reduced and the adjusting accuracy can enhanced.

  • Publication number: 20060180860
    Abstract: An image sensor including an image sensing device layer, a silicon-on-insulator (SOI) layer, an optical device array and a substrate is provided. The SOI layer has a first surface and a second surface. The image sensing device layer is formed on the first surface of the SOI layer. The optical device array is formed on the second surface of the SOI layer. The substrate is disposed above the second surface of the SOI layer; the optical device array is disposed between the substrate and the SOI layer. An incident light coming from the outside environment, passes through the optical device array and the SOI layer, and is received by sensing devices formed in the image sensing device layer. In this manner, the probability of absorption or reflection of the incident light is reduced. Therefore, the sensing performance and the yield of the image sensor of the present invention is improved.

  • Patent number: 6583484
    Abstract: A method for manufacturing a photodiode CMOS image sensor. A first well and a second well are formed in a first type substrate. An isolation layer is formed over the first well and the second well. At the same time, an isolation layer is formed over another region to pattern out an active region for forming the photodiode. A protective ring layer is formed over the peripheral area of the photodiode active region. A first gate structure and a second gate structure are formed above the first well and the second well respectively. A first type source/drain region and a second type source/drain region are formed in the first well and the second well respectively. Concurrently, a second type heavily doped layer is formed in the first type substrate inside the area enclosed by the protective ring layer. A high-energy ion implantation is carried out to form a second type lightly doped layer in the first type substrate just outside the second type heavily doped layer.
