  • Patent number: 10090216
    Abstract: A semiconductor package includes a block having opposing first and second main surfaces and sides between the first and second main surfaces, and an encapsulation material at least partly covering the block. One or both of the main surfaces of the block has recessed regions. The recessed regions do not extend completely through the block from one main surface to the other main surface. The encapsulation material fills the recessed regions to form an interlocked connection between the block and the encapsulation material. Additional semiconductor package embodiments are provided.

  • Patent number: 9627305
    Abstract: A semiconductor package includes a support substrate having opposing first and second main surfaces and sides between the first and second main surfaces, a semiconductor die attached to one of the main surfaces of the support substrate, and an encapsulation material at least partly covering the support substrate and the semiconductor die. A protrusion extends outward from a side of the support substrate and terminates in the encapsulation material. The protrusion forms an interlocked connection with the encapsulation material. The interlocked connection increases the tensile strength of the interface between the encapsulation material and the side of the support substrate with the protrusion.

  • Patent number: 7183022
    Abstract: A method for producing a mask set for lithography including at least one mask, has a predetermined layout of structures which are provided for imaging into a common exposure plane and which are transferred to the masks as a basis. Strongly coupled structures that are so closely adjacent one another, at least in sections, that they are strongly coupled in the case of simultaneous imaging are distributed between at least two different masks of the mask set.

  • Patent number: 6993455
    Abstract: In the method, which is to be carried out on a computer system, firstly design data of a semiconductor substrate are read in and, on the basis thereof, a mask image is generated in the form of a data structure with contact holes and with auxiliary structures on the computer system. Afterwards, contact hole biases are determined by means of an optical proximity correction method and the relevant contact holes are corrected on the basis of these contact hole biases. By means of subsequent imaging simulation of the mask image on the semiconductor substrate, undesired imaging auxiliary structures and contact holes deviating from specified tolerances on the semiconductor substrate are detected and corrected. During the imaging simulation of the mask image, a mask bias is employed in order to compensate for three-dimensional mask effects. A real mask can be produced on the basis of the mask image thus determined.
