  • Publication number: 20240086611
    Abstract: Systems, methods and devices are provided, which can include an engineering change order (ECO) base. A base layout cell includes metal layer regions, conductive gate patterns arranged above metal layer regions; oxide definition (OD) patterns, metal-zero layer over oxide-definition (metal-zero) patterns, at least one cut metal layer (CMD) pattern; and at least one via region. The base layout cell can be implemented in at least two non-identical functional cells. A first functional cell of the at least two non-identical functional cells includes first interconnection conductive patterns arranged connecting metal-zero structures corresponding to at least two metal-zero patterns in a first layout, and a second functional cell of the at least two non-identical functional cells includes second interconnection conductive patterns arranged connecting metal-zero structures corresponding to at least two metal-zero patterns in a second layout.

  • Publication number: 20110181165
    Abstract: A light emitting diode (LED) lamp has a seat with a base, a cover mounted on the seat, and an AC fan, a heat sink and an AC LED light source mounted in the seat. The AC fan and the AC LED light source are electrically connected to the base of the seat. An AC directly provides to and drives the AC fan and the AC LED light source and no converter module is needed. Therefore, the LED lamp is quiet, energy saving and has good heat dissipation and low manufacturing costs for a prolonged operating life.
