摘要： Various semiconductor package arrangements and methods that improve the reliability of wire bonding a die to ground or other outside contacts are described. In one aspect, selected ground pads on the die are wire bonded to a bonding region located on the tie bar portion of the lead frame. The tie bar is connected to an exposed die attach pad that is downset from the bonding region of the tie bar. In some embodiments, the bonding region and the leads are at substantially the same elevation above the die and die attach pad. The die, bonding wires, and at least a portion of the lead frame can be encapsulated with a plastic encapsulant material while leaving a contact surface of the die attach pad exposed to facilitate electrically coupling the die attach pad to an external device.

摘要： A semiconductor chip package having multiple leadframes is disclosed. Packages can include a first leadframe having a first plurality of electrical leads and a die attach pad having a plurality of tie bars, a second leadframe generally parallel to the first leadframe and having a second plurality of electrical leads, and a mold or encapsulant. Tie bars can be located on three main sides of the die attach pad, but not the fourth main side. Gaps in the first and second plurality of electrical leads can be enlarged or aligned with each other to enable the elimination of mold flash outside the encapsulated region, which can be accomplished with mold cavity bar protrusions. Additional components can include a primary die, a secondary die, an inductor and/or a capacitor. The first and second leadframes can be substantially stacked atop one another, and one or both leadframes can be leadless leadframes.

摘要： The present invention relates to a method and device of measuring the velocity of a target (10) by laser self-mixing. An output beam (2) of a single laser source (1) is split into two sensing beams (4, 5). The two sensing beams (4, 5) are directed on different beam paths to a surface of the moving target (10), wherein said different beam paths are selected to be symmetrical to one another. From a measured intensity variation of the output beam (2) Doppler frequencies of laser radiation of the two sensing beams (4, 5) backscattered from the target (10) are determined. Based on these Doppler frequencies a vertical velocity of the moving target (10) is determined from a difference in the Doppler frequencies and a longitudinal velocity of the moving target (10) is determined from the sum of the Doppler frequencies. The invention allows a simple and low cost design of the device and a simple processing of the measurement signal.

摘要： A variety of semiconductor package arrangements and packaging methods are described that improve the reliability of bonding wires that down bond a die to a die attach pad. In one aspect, selected portions of the top surface of a lead frame (which may be in panel form) are plated (e.g., silver plated) to facilitate wire bonding. The plating covers some, but not all of a die attach surface of the die attach pad. In some preferred embodiments, the plating on the die attach pad is arranged as a peripheral ring that surrounds an unplated central region of the die support surface. In other embodiments, the plating on the die attach pad takes the form of bars or other geometric patterns that do not fully cover the die support surface. Unplated portions of the die support surface are roughened to improve the adherence of the die to the die attach pad, thereby reducing the probability of die attach pad delamination and the associated risks to down bonded bonding wires. The described lead frames may be used in a variety of packages. Most commonly, a die is attached to the die support surface of the die attach pad and electrically connected to the lead frame leads by wire bonding as appropriate. At least one of the die's bond pads (typically the ground bond pad(s)) is down bonded to the die attach pad. The die, the bonding wires and at least portions of the lead frame are then typically encapsulated with a plastic encapsulant material while leaving a contact surface of the die attach pad exposed to facilitate electrically coupling the die attach pad to an external device.
