Customer Presentation: Characterization of 1/f noise at wafer level, using CM300xi-ULN
An investigation of differences, in term of noise performances, detected in a product transferred from a technology to another one, has been conducted on 1.8V n-ch MOS transistor,130nm lithography. The 1/f characterization has been carried out at different overdrive values as low as Vgs-Vth close to zero reaching low noise levels typically undetectable on standard probe stations. The fastest way to do it is to perform measurements at wafer level. CM300x-ULN becomes the suitable probing system, thanks to the completely shielded microchamber, filtered power line, and the positioning of the system after a deep and extensive environment including floor vibration evaluation, AC power line noise and harmonics, low frequency magnetic field strength.

Technical Presentation: mW Test Solutions for 5G-FR2
5G-FR2 is pushing the boundary of RF test in production environments. In particular, the increase in chip complexity is requiring more channels in a single chip, as well as pushing the requirements for parallel test. In order to do this, increasing the density of I/O has required the development of not only larger probing solutions, but higher routing density. I will talk about the larger probe card solutions, looking at the increase of routing with additional routing layers, as well as signal integrity to show that increases in channel count doesn’t necessarily require giving up on mW test capabilities in high volume manufacturing environments.

Technical Presentation: Too hot to test for leading-edge SoC and heterogenous integrated IC stack
Leading-edge AI/Graphic/mobile processors, DRAM devices, and heterogenous integrated IC stacks are all facing the same set of thermal management challenge -- DUT is too hot to test. Even at room temperature wafer chuck setting, a mobile SoC device junction temperature can get well above 100 to 150C. For DRAM full-wafer testing, 1-2K watts of power could be applied during 1-TD testing, posting challenges for test cell thermal management. This results in inaccurate test results, or frequently burned probes which cause test cell downtime. As the heterogenous integration becomes more popular, the thermal challenges to test the base die with multi-chips stacked on top further exuberate as the thermal loading per silicon area can increase by order of magnitude. You can’t improve what you can’t measure. FormFactor latest low-thermal-resistance (LTR) wafer chuck technology applies multiple temperature sensors to accurately detect DUT temperature and adjust heat dissipation to achieve the desired test temperature. LTR has shown promising results in production test to address the “too hot to test” challenge.
