Abstract In this paper we present the advanced optical testing of an array fabricated in IBM’s 65 nm SOI CMOS technology, using the Picosecond Imaging Circuit Analysis (PICA) [1-11] tool equipped with the Superconducting Single-Photon Detector (SSPD) [12,13]. Based on the results of the optical analysis we were able to confirm a time collision problem in the readout circuit of the array. In the following sections we will also discuss the use of an innovative optical packaging for testing chips requiring wire-bonding, along with record low voltage optical measurements, down to 0.7 V.

Abstract In this paper we examine the use of the Superconducting Single-Photon Detector (SSPD) [1] for extracting electrical waveforms on an IBM microprocessor fabricated in a 0.13µm technology with 1.2V nominal supply voltage. Although the detector used in our experiments is prototype version of the one discussed in [1] demonstrating lower performance, we will show that it provides a significant reduction in acquisition time for the collection of optical waveforms, thus maintaining the usability of the PICA technique for present and future low voltage technologies.

Abstract In this paper, we present a Superconducting Nanowire Single Photon Detector (SnSPD) system and its application to ultra low voltage Time-Resolved Emission (TRE) measurements (also known as Picosecond Imaging Circuit Analysis, PICA) of scaled VLSI circuits. The 9 µm-diameter detector is housed in a closed loop cryostat and fiber coupled to an existing Emiscope III tool for collecting spontaneous emission light from the backside of integrated circuits (ICs) down to a world record 0.5 V supply voltage in a few minutes.

Abstract This paper describes the analysis of a Phase-Locked Loop (PLL) internal phase detection circuit built in IBM’s 0.13 µm Silicon On Insulator (SOI) CMOS technology by using the Picosecond Imaging Circuit Analysis (PICA) [1,2] tool equipped with the high quantum efficiency Superconducting Single-Photon Detector (SSPD) [3,4]. Signals corresponding to the internal nodes of the PLL are for the first time measured and compared to circuit simulations in order to characterize the behavior of the different components of the circuit.
