Whitepaper: Semiconductor Wafer Measurement for Increased Productivity
Semiconductor Wafer Measurement for Increased Productivity This three-part article describes how manufacturers leverage capacitance-based inspection systems for semiconductor wafers. The article reviews best-practices, consequences of failing to inspect semiconductor wafers and benefits of using semi-automated, fully-automated and manual systems for wafer metrology and inspection. Part 1: Why Disc Geometry Matters in Wafer Production Semiconductor wafers are cut from cylindrical silicon crystals, or ingots. The flatness of these disc-shaped wafers is controlled to tight tolerances to ensure that the entire wafer surface is suitable for integrated circuit (IC) production. If disc geometry is out-of-spec [...]
Cable Testing Applications
Cable failures can shut down production, compromise safety, and create costly compliance risks. That’s why manufacturers across aerospace, EV, medical, industrial, telecommunications, and defense industries rely on Vitrek cable testing solutions to verify performance, insulation integrity, and long-term reliability before products ever reach the field. Vitrek’s advanced cable testing platforms help manufacturers meet demanding industry and regulatory standards while improving throughput, traceability, and quality assurance. From high-voltage harnesses to mission-critical interconnects, Vitrek automated cable testing solutions deliver safer products, stronger compliance documentation, and greater confidence in every connection. Hipot Testing for Electrical Safety Compliance [...]
Adding a Digital Panel Meter to MTI Analog Output Products
Adding a Digital Panel Meter to MTI Analog Output Products Consumer Electronics Electronics Parts Profiling Thickness Description Some MTI Products with Analog outputs, Accumeasure 9000 and Microtrak 3 laser  How To Use Digital Displays with Analog Outputs MTI Microtrak 3 Lasers and some of our Accumeasure amplifiers such as the Accumeasure 9000 only have analog outputs. If you wish to add a digital display, then the Lascar Panel pilot © makes a nice cost effective (~ $110) addition - Fig 1. These Digital panel meters have both 1 & [...]
Thickness Gauge Measurement With Conductive Wafers and Thin Films
Thickness Gauge Measurement With Conductive Wafers and Thin Films Consumer Electronics Electronics Parts Profiling Thickness Description Using MTI's capacitive thickness gauge Proforma 300i with conductive wafers and thin films G = (a+b+t1+t2 ) Where G is the fixed gap between two probes When making the thickness measurement t2 can appear as t2 (film thickness) when it is a conductor, or 0 thickness when t2 is just air. So t2 will vary between the actual film thickness t2 if it's a conductor all the way down to 0 thickness if the [...]
Testing for Connector Failure Due to Vibration or Shock
Testing for Connector Failure Due to Vibration or Shock Mobile Communications Equipment Needs Reliable Connectors That Will Not Disconnect with Shock or Vibration Introduction A large multinational company approached MTI to provide a sensor capable of measuring displacement that also wouldn’t load the target (connector). Shock and vibration testing would span 2-15G and the target connectors were very small. Application MTI’s 2100 optical displacement sensor system is ideal for this kind of application because very small probes can be used and they measure displacement via reflected light. Of course, reflected light does [...]
Camera Shield Measurement
Camera Shield Measurement Consumer Electronics Camera shield measurement Surface Equipment Setup Equipment Used DTS-25-04 laser head Rotary Stage PC with Digital Microtrak Basic Support software Setup: Power is automatic mode. Filter is 100Hz Sample rate is 1000 samples sec The head was operated in diffuse mode (not specular/tilted) Validation of Setup The setup should be validated by performing a total runout scan on the rotary stage with no target present. The stage should be cleaned with Isopropyl alcohol and allowed to dry prior to the scan. This reduces any dust [...]
