  • Publication number: 20240072115
    Abstract: A device includes: a complementary transistor including: a first transistor having a first source/drain region and a second source/drain region; and a second transistor stacked on the first transistor, and having a third source/drain region and a fourth source/drain region, the third source/drain region overlapping the first source/drain region, the fourth source/drain region overlapping the second source/drain region. The device further includes: a first source/drain contact electrically coupled to the third source/drain region; a second source/drain contact electrically coupled to the second source/drain region; a gate isolation structure adjacent the first and second transistors; and an interconnect structure electrically coupled to the first source/drain contact and the second source/drain contact.

  • Publication number: 20180063914
    Abstract: A micro dimming module for driving at least one LED and supporting a TRIAC dimmer to linearly adjust the illumination of the LED comprises a light board, a rectifier and a controller. The light board is a circuit board with a diameter less than or equal to 3 cm or a side length less than or equal to 3 cm, and the rectifier is built without a RC circuit. Namely, the TRIAC dimmer is capable of remaining in a stable working condition without requiring the RC circuit to supply a holding current, so that the lighting application has the advantages of minimizing volume and accomplishing high adaptability and applicability.

  • Patent number: 9485824
    Abstract: Disclosed is a purely resistive dimming circuit for driving LEDs to emit light and support an LED dimming function. The LEDs are divided into a first string and a second string connected in series with each other. The purely resistive dimming circuit is respectively and electrically coupled to an anode terminal of the first string and an anode terminal of the second string by a driving resistor and a current limiting resistor which are connected in series with each other. The resistance of the driving resistor restricts the LEDs to emit light at different stages to enhance the working efficiency of circuits, while using the property of the current limiting resistor to limit the overvoltage current, so as to achieve a constant power operating effect.
