Packages for an integrated circuit die and methods and leadframes for making such packages are disclosed. The package includes a die, a die pad, peripheral metal contacts, bond wires, and an encapsulant. The die pad and contacts are located at a lower surface of the package. The die pad and the contacts have side surfaces which include reentrant portions and asperities to engage the encapsulant. A method of making a package includes providing a metal leadframe having a die pad in a rectangular frame. Tabs extend from the frame toward the die pad. The die pad and tabs have side surfaces with reentrant portions and asperities. A die is attached to the die pad. The die is electrically connected to the tabs. An encapsulant is applied to the upper and side surfaces of the leadframe. Finally, the leadframe is cut in situ so that the die pad and tabs are severed from the frame, the sides of the package are formed, and the package is severed from the leadframe.

PURPOSE: To obtain the subject new compound capable of giving heat-sensitive media or optical recording media having sufficient heat resistance to a certain extent so as to be subjected to hot laminating when using it as a developer. CONSTITUTION: This new aminobenzenesulfonamide derivative is expressed by formula I or II (X is a 1-6C alkyl or electron-attracting group; (m) is 0-3), e.g. 2-(N-phenylcarbamoyl) aminobenzenesulfonamide or 3-(N-phenylcarbamoyl) aminobenzenesulfonamide. The compound is obtained by reaction of 2- aminobenzenesulfonamide or 3-aminobenzenesulfonamide with phenyl isocyanate. In a heat-sensitive recording medium obtained by providing the surface of a substrate with a recording layer containing, as the main ingredients, a colorless or pale dye precursor and a developer capable of developing color by its reaction with the precursor, or in an optical recording medium having the recording layer containing a light absorber to absorb light to the recording layer to convert it into heat, at least one kind of the compound of formula I or II as a developer is incorporated in the recording layer.
