摘要:
A multi-chip module that includes a conductive element connecting at least two semiconductor devices, the conductive element including enhancements for improving the mechanical coupling between the conductive element and the molded housing of the MCM.
摘要:
A multichip module defining a dc to dc converter employs a monolithic chip containing at least two III-nitride switches (a monolithic CSC chip) mounted on a conductive lead frame. The CSC chip is copacked with an IC driver for the switches and with the necessary passives. The module defines a buck converter; a boost converter, a buck boost converter, a forward converter and a flyback converter. The drain, source and gate pads of the monolithic CSC chip are connected to a lead frame by solder or epoxy or by bumping attach and a conductive connector or wire bonds connect the switch terminal to lead frame.
摘要:
A copper strap for a semiconductor device package having a contact electrically connected to a die electrode, a leg portion electrically connected to a lead frame, a web portion positioned between the contact and the leg portion and connected to the leg portion and a connection region connecting the web portion to the contact. The contact includes a body having a plurality of formations, each of the plurality of formations having a concavity and an opposing convexity positioned to generally face the die electrode.
摘要:
A semiconductor package including a bidirectional compound semiconductor component and two power semiconductor devices connected in a cascode configuration.
摘要:
A solderable back contact for semiconductor die consists of a titanium layer bonded to the bottom of the die. The free surface of the titanium layer is coated with a copper layer. A soft solder layer joins the bottom of the die to a copper lead frame by first heating the die to below the melting point of the solder, and then ultrasonically “scrubbing” the solder to cause it to bond to the die and lead frame with a minimum sized solder fillet.
