چکیده

A current sensing device, namely Hall Effect MOSFET (HEMOS) is proposed. It is experimentally shown that the HEMOS enables a non-contacting, and non-disturbing current measurement, which can be used for IDDQ testing of internal circuit blocks. The HEMOS can be manufactured and integrated in a VLSI with the conventional CMOS process. The HEMOS is also helpful to establish the low standby current by identifying the locations of large standby power consumption (possibly a design fault) using only a few pads.

Adaptive IDDQ: How to Set an IDDQ Limit for any Device Under Test

The combination of deep sub-micron technologies together with System on Chip complexity has brought the Device Under Test (DUT) Quiescent Supply Current (IDDQ ) into the Milliamps (mA) range. This IDDQ level, modulated by Electrical Parameters and Critical Dimensions Process spreads , makes almost impossible to detect the small current increase caused by the presence of a defect into the DUT. T...

This paper presents a real case study on the testing of 8-bit mixed-signal CMOS micro-controller devices by applying the IDDQ testing methodology. The aim of the study is to evaluate the feasibility of using the IDDQ test to enhance the overall fault coverage. Failure analysis operated on the failed sample indicated a good correlation between the fault coverage and the parts that failed the IDD...

The Test and Diagnosis of Fpgas a Dissertation Submitted to the Department of Electrical Engineering and the Committee on Graduate Studies of Stanford University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy

A Field-programmable Gate Array (FPGA) is a configurable integrated circuit that can implement an arbitrary logic design, useful for a wide range of applications. However, because integrated circuit manufacturing is imperfect, defects occur. To cope with defects, which cause an FPGA to function incorrectly, the manufacturer must execute two essential tasks: (1) thorough test to ensure high devi...

Screening VDSM Outliers using Nominal and Subthreshold Supply Voltage IDDQ

Very Deep Sub-Micron (VDSM) defects are resolved as Statistical Post-ProcessingTM (SPP) outliers of a new IDDQ screen. The screen applies an IDDQ pattern once to the Device Under Test (DUT) and takes two quiescent current measurements. The quiescent current measurements are taken at nominal and at subthreshold supply voltages. The screen is demonstrated with 0.18μm and 0.13μm volume data. The s...

Identifying defects in deep-submicron CMOS ICs

Given the oft-cited difficulty of testing modern integrated circuits, the fact that CMOS ICs lend themselves to IDDQ testing is a piece of good fortune. But that valuable advantage is threatened by the rush of semiconductor technology to smaller feature sizes and faster, denser circuits, in line with the Semiconductor Industry Association's (SIA) Roadmap--its forecast for the CMOS IC industry. ...
