摘要:
A method of manufacturing an electronic component includes providing a substrate (101), forming a semiconductor device in the substrate (101), depositing a metal layer (107) over the substrate (101) and electrically coupled to the semiconductor device, depositing a layer (108) of solder over the metal layer, and wire bonding a wire (109) to the metal layer (107).

In one embodiment, semiconductor die are singulated from a semiconductor wafer by forming trenches along singulation lines and initiating a cracks from within the trenches, which propagate through the semiconductor wafer in a more controlled manner.
摘要:
A method for manufacturing a thin semiconductor wafer. A semiconductor wafer is thinned from its backside followed by the formation of a cavity in a central region of the backside of the semiconductor wafer. Forming the cavity also forms a ring support structure in a peripheral region of the semiconductor wafer. An electrically conductive layer is formed in at least the cavity. The front side of the semiconductor wafer is mated with a tape that is attached to a film frame. The ring support structure of the semiconductor wafer is thinned to form the thinned semiconductor wafer. A backside tape is coupled to semiconductor wafer and to the film frame and the tape coupled to the front side of the semiconductor wafer is removed. The thinned semiconductor wafer is singulated.

In one embodiment, an electronic device package (1) includes a leadframe (2) with a flag (3). An electronic chip (8) is attached to the flag (3) with a die attach layer (9). A trench (16) having curved sidewalls is formed in the flag (3) in proximity to the electronic chip (8) and surrounds the periphery of the chip (8). An encapsulating layer (19) covers the chip (8), portions of the flag (3), and at least a portion of the curved trench (16). The curved trench (16) reduces the spread of die attach material across the flag (3) during chip attachment, which reduces chip and package cracking problems, and improves the adhesion of encapsulating layer (19). The shape of the curved trench (16) prevents flow of die attach material into the curved trench (16), which allows the encapsulating layer (19) to adhere to the surface of the curved trench (16).

In one embodiment, a packaged semiconductor device having enhanced thermal dissipation characteristics includes a lead frame structure and a semiconductor chip having a major current carrying or heat generating electrode. The semiconductor chip is oriented so that the major current carrying electrode faces the top of the package or away from the next level of assembly. The packaged semiconductor device further includes a non-planar, stepped or undulating attachment structure coupling the current carrying electrode to the lead frame. A high thermal conductivity mold compound and thin package profile further enhance thermal dissipation.
