Patent number: 10192837Abstract: A wafer-level chip-scale package (WLCSP) includes an integrated circuit (IC) chip, and die bonding pads with a redistribution layer (RDL) having multiple via structures located directly below the footprint of a solder ball placed on the bonding pad. The via structures electrically connect the solder ball to a top metal layer of the IC chip. The RDL may extend beyond the solder ball's footprint and have additional vias that connect to the top metal layer, including vias located under and connected to other solder balls. The bonding pads have a low R-on resistance and are not susceptible to thermal-induced cracking.Type: GrantFiled: December 20, 2017Date of Patent: January 29, 2019Assignee: NXP B.V.Inventors: Chung Hsiung Ho, Wayne Hsiao, Richard Te Gan, James Raymond Spehar

Publication number: 20120286588Abstract: A switching circuit employs MEMS devices. In connection with various example embodiments, signal switching circuit couples primary and secondary data link connectors having at least two channels and an electrode for each channel. A MEMS switch is coupled to each channel in of the secondary data link connectors, and includes a suspended membrane, first and second contact electrodes (one being in the membrane) and a biasing circuit that biases the membrane for moving the membrane between open and closed positions to contact the electrodes. A switch controller circuit selectively controls the application of an actuation voltage to each of the biasing circuits, thereby selectively actuating the membranes between the open and closed positions for routing signals between the primary and secondary data link connectors.Type: ApplicationFiled: May 11, 2011Publication date: November 15, 2012Applicant: NXP B.V.Inventors: Peter Steeneken, Olaf Wunnicke, Klaus Reimann, James Raymond Spehar, Michael Joehren, Gerrit Willem den Besten

Publication number: 20120286846Abstract: A switching circuit employs switches operating at low on resistance and high off capacitance. In connection with various example embodiments, a switching circuit selectively couples a communication port to one of two or more internal circuits based upon a type of input at the communication port. A sensor circuit senses the type of the input and, based upon the sensed input type, actuates one or more switches in the switching circuit.Type: ApplicationFiled: May 11, 2011Publication date: November 15, 2012Inventors: Olaf Wunnicke, Willem Frederik Adrianus Besling, Gerrit Willem den Besten, Michael Joehren, Klaus Reimann, James Raymond Spehar, Peter Gerard Steeneken

Publication number: 20120137025Abstract: Bus communications are effected. In accordance with one or more example embodiments, a bus circuit is configured for communicating data in accordance with a main protocol (e.g., as a default), and for communicating with an alternate protocol when signals corresponding to the main protocol are not present. In some implementations, a sense circuit is used with input pins to sense a type of signal for bus communications, and to control communications on the bus with a protocol appropriate for the sensed signals, and for a main protocol when main protocol signals are sensed (e.g., for a default bus operation, or for test operation).Type: ApplicationFiled: November 29, 2010Publication date: May 31, 2012Inventors: David Ross Evoy, James Raymond Spehar
