摘要： A method of assembling semiconductor devices includes placing an array of semiconductor dies on a die support. A cap array structure is provided that has a corresponding array of caps supported by a cap frame structure. The cap array structure and the array of semiconductor dies on the die support are aligned, with the caps extending over corresponding semiconductor dies, in a mold chase. The array of semiconductor dies and the array of caps are encapsulated with a molding compound in the mold chase. The encapsulated units of the semiconductor dies with the corresponding caps are removed from the mold chase and singulated. Singulating the encapsulated units may include removing the cap frame structure from the encapsulated units.

摘要： A no-lead type semiconductor package is formed by attaching a die to a top surface of a flag of a lead frame and then taping a bottom surface of the flag and leads of the lead frame. Die bonding pads are connected to the leads with wires and then the assembly is put in a mold chase and encapsulated with a plastic material. The mold chase has protrusions between the flag and the leads of a lead frame, and between the leads themselves, which causes indentations to be formed between the leads and between the flag and the leads. The method is particularly useful for making quad flat no lead (QFN) devices and power-QFN type devices.

摘要： A semiconductor die package is assembled from a lead frame having lead fingers with a bonding end adjacent a die flag, and an elongate region extending away from the die flag. A semiconductor die is mounted on the die flag and electrodes of the semiconductor die are electrically connected to the bonding ends with bond wires. Each elongate region is bent into an external connector lead with mounting feet. The elongate region of each of the lead fingers protrudes from a housing formed from a mold compound. The mold compound extends from the housing to provide insulated support fingers molded to the external connector leads.
