Patent number: 10262926Abstract: A semiconductor die has internal circuitry formed on two more internal layers, and die bonding pads arranged on a top surface of the die. The bonding pads are connected to the internal circuitry for providing input and output signals to the internal circuitry. One or more connecting lines electrically connect one or more pairs of the die bonding pads, thereby defining a bonding pad layout. The die bonding pads are arranged and connected with the connecting lines such that the bonding pad layout is reversible, which allows the die to be used in different package types (e.g., TSSOP or DFN) yet maintain a standardized pin arrangement without the necessity for long or crossed bond wires.Type: GrantFiled: October 5, 2016Date of Patent: April 16, 2019Assignee: Nexperia B.V.Inventors: Kan Wae Lam, Harrie Martinus Maria Horstink, Sven Walczyk, Chi Ho Leung, Thierry Jans, Pompeo V.

Patent number: 5812715Abstract: The invention relates to an optoelectronic device with a module comprising a holder with an amplifier and on either side thereof a lens and a glass fiber which can be aligned relative to the amplifier. The module also comprises two monitor diodes. A disadvantage of the known device is that the lenses cannot be easily aligned relative to the amplifier, and the monitor diodes cannot be easily connected electrically. The use of a spherical lenses also poses a problem. In a device according to the invention, the monitor diodes are so positioned that they are capable of detecting radiation reflected at the outside of the lenses instead of radiation refracted and reflected within the lenses, while the radiation-sensitive surfaces of the monitor diodes are positioned such that they receive more radiation from one lens than from the other lens.Type: GrantFiled: January 21, 1997Date of Patent: September 22, 1998Assignee: U.S. Philips CorporationInventors: Lukas F.
