  • Publication number: 20240112963
    Abstract: A semiconductor structure is provided. The semiconductor structure includes a semiconductor wafer and a test structure. The semiconductor wafer has a substrate having a scribe line area, a first die area and a second die area. The first die area and the second die area are separated by the scribe line area extending along a first direction. The test structure is disposed in the scribe line area. The test structure includes a test device and a first test pad. The test device has a physical characteristic similar to a semiconductor device fabricated in the first die area or the second die area. The first test pad is electrically connected to the test device. A first distance between the first test pad and the first die area gradually increases from a center region to a peripheral region of the first test pad in the first direction.

  • Patent number: 8283689
    Abstract: An LED device and LED module are provided. The LED device is coupled to a lead frame with a first plane and a second plane opposite to the first plane, the lead frame having a LED chip disposed on the first plane. The LED device includes a reflection cup structure disposed on the lead frame, a lens structure and at least one fixing structure. The LED chip is disposed in the reflection cup structure and electrically connected to the first plane of the lead frame. The lens structure covers the first plane and the second plane of the lead frame. The fixing structure and the fixing structures are formed integrally and cover the lead frame cooperatively.
