Publication number: 20150028898Abstract: A sense resistor is coupled between a power source and one or more power pins of an integrated circuit (IC) chip including a circuit component (e.g., a microcontroller unit (MCU)). An on-chip amplifier (e.g., a programmable gain amplifier or op-amp) amplifies the voltage drop over the sense resistor to a level that is within the dynamic range of an on-chip analog-to-digital converter (ADC). In some implementations, the measured signals can be time-stamped and stored in a trace buffer and aligned with other trace data using a front-end tool (e.g., a personal computer). In some implementations, circuitry is included for detecting and handling power consumption events associated with the circuit component. In some implementations, a program counter associated with the circuit component is synchronously sampled with the power consumption measurements and/or other data sources.Type: ApplicationFiled: July 29, 2013Publication date: January 29, 2015Applicant: Atmel CorporationInventors: Ingar Hanssen, Jo Inge Lamo

Publication number: 20150028907Abstract: A probe apparatus of inspecting electrical characteristics of a power device having electrodes on both sides of a substrate at wafer level can reduce and uniformize a contact resistance between the electrode on a rear surface of the substrate and a mounting surface conductor of a chuck top. In the probe apparatus, an attracting device supports a semiconductor wafer W on the chuck top 12, and has many vertical fine holes in a pattern (diameter ? and pitch p) that satisfies the condition of ?<p?2?. For example, the diameter ? is about 0.25 mm, and the pitch p is about 0.5 mm.Type: ApplicationFiled: July 28, 2014Publication date: January 29, 2015Inventors: Eiichi Shinohara, Munetoshi Nagasaka, Isamu Inomata, Kazuya Yano, Yoshiyasu Kato
