DRAM Test And Inspection Just Gets Tougher
By Anne Meixner - 07 Nov, 2023 - Comments: 0

DRAM manufacturers continue to demand cost-effective solutions for screening and process improvement amid growing concerns over defects and process variability, but meeting that demand is becoming much more difficult with the rollout of faster interfaces and multi-chip packages. DRAM plays a key role in a wide variety of electronic devices, from phones and PCs to ECUs in cars and servers ins... » read more

Integration Challenges For ATE Data
By Gregory Haley - 10 Oct, 2023 - Comments: 0

Tighter integration of automatic test equipment (ATE) into semiconductor manufacturing, so that data from one process can be seamlessly leveraged by another, holds significant promise to boost manufacturing efficiency and yield. The challenge is selling this concept to fabs, packaging houses, and their customers. Data involving yield parameters, process variations, and intricate details abou... » read more

Test Strategies In The Era Of Heterogeneous Integration
By Fisher Zhang - 12 Sep, 2023 - Comments: 0

Moore’s Law, the observation that the number of transistors on an integrated circuit doubles approximately every two years, is critical to advances in computing technology. For decades, fabs have managed to achieve exponential growth in digital capability and transistor density by making transistors smaller and smaller, but we’ve hit the physical limits of these processes. Today, new proces... » read more

MMAF Option Enables Picoampere Measurements
By Yoshiyuki Aoki - 12 Sep, 2023 - Comments: 0

By Yoshiyuki Aoki and Tsunetaka Akutagawa Demand for low-current devices is increasing, as many new sensors are being created for medical, automotive, industrial, and other applications. Chief among the heightened production and test requirements for these low-current devices is the need to achieve picoampere (pA)-class measurements. Sensors’ functionality and efficacy, especially in medic... » read more

SiC Growth For EVs Is Stressing Manufacturing
By Anne Meixner - 08 Aug, 2023 - Comments: 0

The electrification of vehicles is fueling demand for silicon carbide power ICs, but it also is creating challenges in finding and identifying defects in those chips. Coinciding with this is a growing awareness about just how immature SiC technology is and how much work still needs to be done — and how quickly that has to happen. Automakers are pushing heavily into electric vehicles, and t... » read more

How To Boost ATE Power Supply Throughput
By Keysight - 26 Jul, 2023 - Comments: 0

The test engineer’s job is not an easy one. There is constant pressure to improve system throughput. This white paper will guide you on how to increase throughput to reduce costs. Increased throughput comes from faster programming and command processing times, built-in output sequencing, and arbitrary waveform capabilities. Faster testing speeds will enable more rigorous testing of devices, d... » read more

Design Considerations For Ultra-High Current Power Delivery Networks
By Quaid Joher Furniturewala - 11 Jul, 2023 - Comments: 0

This article is adapted from a presentation at TestConX, March 5-8, 2023, Mesa, AZ. A power-delivery network (PDN), also called a power-distribution network, is a localized network that delivers power from voltage-regulator modules (VRMs) throughout a load board to the package’s chip pads or wafer’s die pads. The PDN includes the VRM itself, all bulk and localized capacitance, board vi... » read more

Power-Supply Card Targets High-Voltage PMIC Test
By Toni Dircherl - 06 Jun, 2023 - Comments: 0

The electronics industry is seeing a move toward higher voltages and currents to deliver sufficient supply and charging power in products ranging from handheld cellphones and tablets to workstations. This trend is evidenced in examples such as the many USB power-delivery (PD) profiles with ratings ranging from 10W (5V at 2A for USB PD 3.0 profile 1) up to 100W (5V at 2A, 12V at 5A, and 20V at 5... » read more

Pinpointing Timing Delays Can Improve Chip Reliability
By Anne Meixner - 09 May, 2023 - Comments: 0

Growing pressure to improve IC reliability in safety- and mission-critical applications is fueling demand for custom automated test pattern generation (ATPG) to detect small timing delays, and for chip telemetry circuits that can assess timing margin over a chip's lifetime. Knowing the timing margin in signal paths has become an essential component in that reliability. Timing relationships a... » read more

Optimizing Scan Test For Complex ICs
By Gregory Haley - 09 May, 2023 - Comments: 0

As chips become more heterogeneous with more integrated functionality, testing them presents increasing challenges — particularly for high-speed system-on-chip (SoC) designs with limited test pin availability. In addition, the complexity of emerging packages like 3D and chiplets necessitates comprehensive new solutions that can provide faster results at multiple stages in the silicon lifec... » read more
