Improved Test Methodology for Production Testing of RF Switches Using a New Relative Measurement Technique

High-volume production testing using automatic test equipment (ATE) is an important part of the integrated circuit manufacturing industry, where it allows products to be rigorously characterized to ensure conformity with their data-sheet specifications. When used in production, the accuracy and repeatability of the ATE must itself be understood so that the final measurements are a true reflection of the underlying product performance and are not adversely influenced by variations or inaccuracies in the ATE setup. This paper reports on the application of the ATE to production testing of CMOS solid-state RF switches operating at 1 GHz and the steps that have been taken to remove sources of variation from the measurement setup. In particular, a calibration path based on the solid-state GaAs switches, which shares most of the RF signal path with the device under test (DUT), is described. The introduction of the calibration path reduces the variability of the measurement system by up to 60%, thus ensuring the suitability of the new setup for an ongoing high-volume production test.

An Information-Rich Automatic Calibration Concept

Calibration appears to be an area in which automation can produce a significant improvement in productivity. However, the degree of success in automating the calibration function is highly dependent on the approach chosen. This approach must account for the workload characteristics commonly found in calibration operations, yet must be flexible enough to offer a solution for new and/or unique methods of managing calibration operations. ROLAIDS (Reconfigurable On-Line ATE Information Distribution System) is one such approach.

Considerations for, and Impact of, the ATE/UUT Interface

This paper discusses the motivations for establishing a centralized interface for ATE and the problems which emanate from implementing that decision. The theme developed is that the advantages of centralized highly capable interface are bought dearly most often with compromise of performance and risk of obsolescence. Discussion elements include: advantages of grouped versus distributed mechanical configuration; physical and electrical impact of "standard" ATE interfaces; and testing complications introduced by complex automated interfaces. The user/developer of an ATE system is cautioned to evaluate the performance impact of the ATE interface as it affects his total testing mission. Some basic considerations are presented to assist in this evaluation.

Analysis and measurement of fault coverage in a combined ATE and BIST environment

This paper analyzes an environment which utilizes built-in self-test (BIST) and automatic test equipment (ATE), and presents closed-form expressions for fault coverage as a function of the number of BIST and ATE test vectors. This requires incorporating the time to switch from BIST to ATE (referred to as switchover time), and utilizing ATE generated vectors to finally achieve the desired level of fault coverage. For this environment, we model fault coverage as a function of the testability of the circuit under test and the numbers of vectors which are supplied by the BIST circuitry and the ATE. A novel approach is proposed; this approach is initially based on fault simulation using a small set of random vectors; an estimate of the so-called detection profile of the circuit under test is established as the basis of the test model. This analytical model effectively relates the testable features of the circuit under test to detection using both BIST and ATE as related testing processes.     

Adaptive optimal design of active thermoelectric windows using surrogate modeling

This paper develops an optimal design and an optimal operating strategy for Active Thermoelectric (ATE) windows. The proposed ATE window design uses thermostats to actively control thermoelectric (TE) units and fans to regulate the heat transfer through the windows. To achieve high energy efficiency, optimization of the ATE window design seeks to simultaneously minimize the heat transferred through the window and the net power consumption. The ATE windows should adapt to varying climatic conditions. The heat transfer and the power supplies are optimized under a prescribed set of climatic conditions. Based on the optimal results obtained for these conditions, surrogate models are developed to represent the optimal modes of operation as functions of the climatic conditions, namely (i) ambient temperature, (ii) wind speed, and (iii) solar radiation. To this end, Radial Basis Functions (RBF) are used. The results show that the ATE windows provide significantly improved insulation compared to traditional windows under varying climatic conditions. Moreover, it was found that the ATE window operates at a superior efficiency than a standard HVAC system, particularly in colder climates.
