Sallands vision on the Future of Test

Opening of the Symposium and welcome speech by Paul van Ulsen, CEO and owner of Salland Engineering, where he will share Salland's vision on the future of semiconductor test.


Paul has over 37 years’ experience in Semiconductor Test and is currently responsible for all aspects of corporate governance and business development for Salland Engineering worldwide. He is a graduate of Windesheim Technical University in electronics and computer engineering.

In 1986, Paul started his career as Test Application engineer at Rood Testhouse, where he was involved in many Mixed Signal test solutions. In 1992, he continued as Application engineer at Salland and moved soon into new roles like; project management, HR and Sales which made him decide to choose to be the Sales Director, followed becoming the CEO and in 2017 the owner of Salland Engineering world-wide. In 2018 he acquired Applicos, a leading Analog post-silicon-validation test solution provider, and successfully integrated this into Salland family.

Tessent™ Streaming Scan Networks (SSN): An Introduction for Test & Product Engineers

The increasing complexity in large System on Chip (SoC) designs presents challenges to all IC design disciplines, including design-for-test (DFT), Product & Test Engineering. Tessent™ Streaming Scan Network (SSN) is a system for packetized delivery of scan test patterns. It enables simultaneous testing of any number of cores with few chip-level pins and reduces test time and test data volume. With SSN, DFT engineers now have a true SoC DFT solution without compromises between implementation effort and manufacturing test cost. It can test any number of identical core instances in near-constant time, minimizes padding in the presence of cores with mismatched pattern counts and/or scan chain lengths and enables fast streaming of data to/from and throughout the chip. It simplifies design planning and implementation and is especially well suited for tile-based designs.

This presentation describes the basic components of the Tessent™ Streaming Scan Network and highlights some of the key benefits for Test & Product Engineers with respect to bring-up and volume manufacturing including:

  • Reduced pattern counts, test volume and test cost
  • Efficient testing of duplicate cores
  • Flexibility of test scheduling & execution
  • Improved power and IR-Drop profiles
  • Diagnostics support

Challenges and Developments in Reliability Testing

Computing power is increasing in semiconductor development. Which results in increasing energy dissipation of a DUT, raising of voltage levels and decrease of ESD voltage levels due to upscaling of package size. How can reliability tests be performed reliable on those devices? What is the impact on the current process and how can we stay ahead of these challenges? What is the effect of ESD protection on larger devices packages and how can we continue to ESD test those devices? And what is the impact of high-level voltages for reliability testing? A lot of challenges where Eurofins | MASER is working on to be ready for future reliability testing.

He earned his Bachelor in Electrical engineering from Saxion Hogeschool in Enschede, The Netherlands, in 2002. Following his graduation, he joined Texas Instrument as a EMC test Engineer. In 2004 he transitioned to Failure analysis Quality engineer in München region and 2007, Wouter promoted to Supervisor Failure Analysis location Almelo (Sensata technologies B.V. as of 2016). Expending his responsibilities as Supervisor of the Sofia analysis team in 2020. In 2021 he promoted to Reliability lab and Failure analysis Manager location Hengelo and started his role as Reliability Department manager of Eurofins | MASER begin 2022.

Testing a 2x25W class D output stage

Battery driven audio playback devices with high output power is an increasing market. Most of these systems have a plastic enclosure in which heat convection to the environment is limited. It requires high efficient class D power conversion to limit the power losses and temperature increase. A two channel Bridge Tied Load (BTL) power stage of this market will be presented that can deliver 2x25W in 4Ω loads and is packaged in a small QFN-28 package. The test program of this device is developed at Salland. A detailed explanation will be given of the gate oxide stress test and on-resistance test that are optimized by making use of dedicated embedded circuits.

New Methods & Tools in MEMS/Photonic Testing

Silicon-based Devices other than ICs have varied working principles that go beyond the electronic: photonics, fluidics, MEMS, quantum etc. The utility of a given SBD from this group is usually tightly connected to what the manufacturing process can offer. Special functional (bio)layers, custom etched structures, buried flow channels, chip combinations and other non-standard features are usually needed for a product to exhibit its unique selling point at the end. It is therefore essential that testing - sometimes also referred as qualification - of such devices extracts information that goes beyond the one provided by only electrical contacting. In this presentation we couple the testing needs of non-IC SBDs to various potential probing methods and present the tools we are developing for that purpose.

Signal-chain noise application and challenges

One of the greatest challenges in designing a precision data acquisition measurement signal chain is managing and minimizing the noise. There are design trade-offs that balance the noise contribution of the different stages of the signal chain to establish the optimum signal conditioning solution between the sensor and the digitizer input. In this presentation, we will provide some background to these challenges before presenting our Noise Tool, a web-based tool designed to build, simulate, and verify complex precision signal chains. We will also announce the up-coming release of the lowest noise spectral density ADC on the market and go into detail on how Salland Engineering are enabling us to evaluate performance at the leading edge of technology.

Tackling the quantum device testing bottleneck

Quantum computing has the potential to solve complex problems faster than classical computers. However, for practical commercial applications, we need quantum chips with more qubits that are of significantly better quality. To achieve this, we must explore novel approaches inspired by the mature semicon industry. Quantum chip testing in particular poses a significant bottleneck in realizing practical quantum computing. Here, we will explore the unique aspects of quantum testing compared to classical chip testing. In contrast to conventional CMOS metrology and testing, no simple correlations exist between conventional optical inspection and information processing parameters of a quantum chip. The full performance of a quantum chip can therefore only be measured by calibrating and tuning up the qubits to levels of quantum computing operating conditions. Superconducting as well as semiconductor-based quantum chips do not operate in ambient conditions, but need to be isolated and shielded, involving high vacuum, ultra-low (~20mK) temperatures, and low-power microwave electromagnetic signals. Tuning up qubits requires a framework for executing physics-based control sequences and protocols that also allow for the automation of the tasks usually performed manually by experienced quantum engineers. Join us to delve into the intricacies of quantum chip testing and understand its vital role in making quantum computing a commercial reality.

Elevating Innovation in ATE Semiconductors

As quickly as the semiconductor industry evolves and advances, requirements for testing chips is also expanding at a rate that is challenging to keep up with. Testing Quick Charging, UCie standards, and automotive power, are industry challenges that ATE manufactures are facing and need to develop solutions for. With ElevATE’s new silicon strategy, modularity, future reuse, and time to market, we are driving our engineering decisions and paving the road for intelligent solutions to be developed. Chiplets, also known as heterogeneous integration, will be laying the foundation of the ATE future from both a tester integration perspective and an external testing perspective.

Visual Basic for Applications (VBA) to C-based test program conversion

Converting test programs between tester platforms is the first step for managing tester capacity. However, text-based programs and table-based programs have fundamental differences which usually requires lots of human efforts to look into the details. This session shares the approaches and potential methods to automate the conversion process. The preliminary result shows significant reduction in conversion time and much reduced test debugging efforts.
