  • Publication number: 20060239316
    Abstract: The present invention relates to an apparatus for controlling temperature of an optical module using an uncooled laser diode. A first setup unit for establishing low-temperature setup voltage and a second setup unit for establishing high-temperature setup voltage determine first and second threshold voltages suitable for low-temperature and high-temperature setup voltages, respectively. First and second comparators compare the low-temperature and high-temperature setup voltages with sensor voltage received from a sensor voltage entry unit, respectively. The output signals of the comparators are applied to a logic circuit, such that the logic circuit generates on/off signals according to the result of the comparison. The logic circuit generates a high-level signal only when the sensor voltage escaped from a predetermined voltage range, and thus operates the temperature control circuit.

  • Patent number: 7002849
    Abstract: A method for programming and erasing a non-volatile memory with a nitride tunneling layer is described. The non-volatile memory is programmed by applying a first voltage to the gate and grounding the substrate to turn on a channel between the source and the drain, and applying a second voltage to the drain and grounding the source to induce a current in the channel and thereby to generate hot electrons therein. The hot electrons are injected into a charge-trapping layer of the non-volatile and trapped therein through the nitride tunneling layer. The non-volatile memory is erased by applying a first positive bias to the drain, applying a second positive bias to the gate, and grounding the source and the substrate to generate hot electron holes in the channel region. The hot electron holes are injected into the charge-trapping layer through the nitride tunneling layer.

  • Publication number: 20050117855
    Abstract: A latch type optical communication module, designed to9 be easily mounted and detached to a system port having a cage by means of a latch. The optical communication module is provided with a latch: The latch may be rotated around a hinge shaft fixed to both sides of a receptacle while being inserted into latch holes penetrating both ends of the latch. When the latch is rotated and then allows latch drivers to force a slider upward, the slider raises a fixing tap of the optical communication module inserted into the system port, thereby allowing the optical communication module to be detached from the system port. With the construction of the optical communication module, the plurality of additional components are not required for the optical communication module, thereby lowering manufacturing costs, and the optical communication module can be detached from the system port without any tool and any influence against adjacent optical communication module.

  • Patent number: 6709921
    Abstract: A fabrication method for a flash memory device with a split floating gate is described. The method provides a substrate, wherein an oxide layer and a patterned sacrificial layer are sequentially formed on the substrate. Ion implantation is then conducted to form source/drain regions with lightly doped source/drain regions in the substrate beside the sides of the patterned sacrificial layer using the patterned sacrificial layer as a mask. Isotropic etching is further conducted to remove a part of the patterned sacrificial layer, followed by forming two conductive spacers on the sidewalls of the patterned sacrificial layer. The patterned sacrificial layer and oxide layer that is exposed by the two conductive spacers are then removed to form two floating gates. Subsequently, a dielectric layer and a control gate are formed on the substrate.
