  • Publication number: 20150061113
    Abstract: A method of processing semiconductor dies is provided. Each semiconductor die has a first side with one or more terminals, a second side opposite the first side and sidewalls extending between the first and the second sides. The semiconductor dies are processed by placing the semiconductor dies on a support substrate so that the first side of each semiconductor die faces the support substrate and the second side faces away from the support substrate. A coating is applied to the semiconductor dies placed on the support substrate. The coating has a lower reflectivity than the first side of the semiconductor dies. The coating covers the second side and at least a region of the sidewalls nearest the second side of each semiconductor die. The semiconductor dies are removed from the support substrate after applying the coating for further processing as loose dies such as taping.

  • Publication number: 20150004451
    Abstract: An apparatus for determining a state of a rechargeable battery or of a battery has a sensor device and an evaluation device. The sensor device brings about an interaction between an optical signal and a part of the rechargeable battery or of the battery, which part indicates optically acquirable information about a state of the rechargeable battery or of the battery, and detects an optical signal caused by the interaction. The sensor device furthermore provides a detection signal having information about the detected optical signal. The evaluation device determines information about a state of the rechargeable battery or of the battery on the basis of the information of the detection signal. Furthermore, the evaluation device provides a state signal having the information about the determined state.
