Wafer Backgrinding and Semiconductor Thickness Measurements

Wafer Backgrinding and Thickness Measurements in Semiconductor Manufacturing Wafer backgrinding, also known as wafer thinning or wafer lapping, is a critical step in semiconductor packaging. This process, which involves grinding the backside of a semiconductor wafer, reduces its thickness to enable the stacking of integrated circuits (ICs) and support high-density packaging. The thickness of the wafer plays a crucial role in determining the overall size of the package, an important factor as modern electronics such as smartphones, laptops, and other devices continue to get thinner and more compact. In applications like MEMS (Micro-Electro-Mechanical Systems), the backgrinding process also affects [...]

The Growing Need for Industry 4.0 Testing and Validation Tools

Industry 4.0 means that manufacturers need to test and validate more sensors. MTI Instruments 1510A portable signal generator can help. Industry 4.0 is spurring a dramatic increase in the number of sensors that manufacturers need to install, test, validate, and maintain. Although these industrial sensors are packaged to withstand harsh environments, they’re still susceptible to performance-related problems. Whether it’s to support predictive maintenance, asset monitoring, or process automation, proper testing and validation is required to keep systems running smoothly. Otherwise, the data that sensors collect won’t enable the operators of smart factories to make the right decisions.Smart factories can [...]

Laser Triangulation Sensor Principles

Laser triangulation sensors can be divided into two categories based upon their performance and intended use. High-resolution lasers are typically used in displacement and position monitoring applications where high accuracy, stability and low temperature drift are required. Quite frequently these laser sensors are used in process monitoring and closed-loop feedback control systems. Proximity type laser triangulation sensors are much less expensive and are typically used to detect the presence of a part, or used in counting applications. Laser Triangulation Sensor Applications Position Sensing General positioning is the [...]

Silicon Carbide vs. Silicon in EV Power Electronics

Compare silicon carbide vs. silicon for electric vehicle (EV) power electronics and learn about SiC wafer measurement. As demand for electric vehicles (EVs) continues to grow, manufacturers are comparing two semiconductor technologies, silicon carbide and silicon, for power electronics applications. Silicon carbide (SiC) provides the high temperature resistance, low power consumption, rigidity, and support for smaller, thinner designs that EV power electronics need. Examples of SiC’s current applications include on-board DC/DC converters, off-board DC fast chargers, on-board battery chargers, EV powertrains, and automotive lighting for LEDs. According to Automotive World, SiC technology could also drive future EV innovations [...]

MTI Instruments Fulfills Historic Order for the United States Air Force

Lockport, IL, November 16, 2020 — MTI Instruments, Inc. (“MTI Instruments”), the operating subsidiary of Mechanical Technology, Incorporated (OTC Pink: MKTY), announces the completion of its historic order for the United States Air Force, a $3.3 million contract awarded publicly in May 2020 that includes 52 PBS-4100+ engine vibration measurement and balancing systems. This order was made pursuant to the multi-year contract entered into by MTI Instruments and the United States Air Force in July 2016 and marks the single largest order of PBS-4100+ Systems received by MTI Instruments to date. MTI fulfilled the order in its entirety with [...]

EV Batteries Need Thickness Gauging for Lower Costs and Higher Performance

EV batteries need to cost less and last longer. Until the e-mobility industry solves these challenges, electric vehicle (EV) adoption won’t match the hype that’s driven by Tesla, the established automakers, and a host of startups who are attracting investors. According to Axios, the expense of owning an electric vehicle will exceed that of owning a conventional one until EV batteries cost less than $100/KWh to produce. Unfortunately, the EV industry isn’t expected to hit that target for another ten years. Yet, there is some encouraging news. Less expensive and better performing EV batteries are just a few years [...]

Transducer Selection for High Resolution Applications

High resolution applications do not always require an interferometer. If you want to make accurate measurements in the micron to picometer range, then an MTI Digital Accumeasure D100 HD or D200 system may be what you need. Laser interferometers can sell for more than $15,000 and be difficult to setup. For example, you may have to buy additional optics to guarantee a good return signal since the laser beam must reflect off a mirror surface or precision retro reflector in order for the beam to re-enter the interferometer’s optics at less than a degree of reflection angle. The downsides [...]
