  • Patent number: 9147639
    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.

  • Patent number: 9099547
    Abstract: In accordance with an embodiment of the present invention, a method of manufacturing a semiconductor device includes providing a wafer having a top surface and an opposite bottom surface. The top surface has a plurality of dicing channels. The wafer has a plurality of dies adjacent the top surface. Each die of the plurality of dies is separated by a dicing channel of the plurality of dicing channels from another die of the plurality of dies. Trenches are formed in the wafer from the top surface. The trenches are oriented along the plurality of dicing channels. After forming the trenches, the plurality of dies is tested to identify first dies to be separated from remaining dies of the plurality of dies. After testing the plurality of dies, the wafer is subjected to a grinding process from the back surface. The grinding process separates the wafer into the plurality of dies.

  • Publication number: 20150090042
    Abstract: A pressure sensor package includes a lead and a semiconductor die spaced apart from the lead and including a terminal and a diaphragm disposed at a first side of the die. The die is configured to change an electrical parameter responsive to a pressure difference across the diaphragm. The package further includes an electrical conductor connecting the terminal to the lead, a molding compound encasing the electrical conductor, the die and part of the lead, a cavity in the molding compound exposing the diaphragm, and a sealing ring disposed on a side of the molding compound with the cavity. The sealing ring surrounds the cavity and has a lower elastic modulus than the molding compound. Alternatively, the sealing ring can be a ridge of the molding compound that protrudes from the side of the molding compound with the cavity and surrounds the cavity. A package manufacturing method is also provided.

  • Patent number: 8937380
    Abstract: A semiconductor package includes a lead spaced apart from a semiconductor die. The die includes a diaphragm disposed at a first side of the die and is configured to change an electrical parameter responsive to a pressure difference across the diaphragm. The die further includes a second side opposite the first side, a lateral edge extending between the first and second sides and a terminal at the first side. An electrical conductor connects the terminal to the lead. An encapsulant is disposed along the lateral edge of the die so that the terminal and the electrical conductor are spaced apart from the encapsulant. The encapsulant has an elastic modulus of less 10 MPa at room temperature. A molding compound covers and contacts the lead, the electrical conductor, the encapsulant, the terminal and part of the first side of the die so that the diaphragm is uncovered by the molding compound.

    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.
