Wire Bonding
Wire Bonding Semiconductor Wire Bonding Level Description Introduction:  Machine automation frequently involves measuring small distances extremely accurately. Wire Bonding is one such application with some challenging requirements. A ‘normal’ wire bond consists of gold wire bonded to a substrate (PC Board) and an integrated circuit. Wire size varies between eighteen and fifty microns, with twenty-five microns being the ‘standard’; pad sizes are typically between seventy-five and one hundred microns wide. Space between two pads is generally one hundred microns. The width of the actual bond is generally 1.2 to 2.5 times [...]
GaAs Substrate Thickness Measurement
GaAs Substrate Thickness Measurement Semiconductor Gaas Substrate Thickness Measurement Thickness Description Measuring Thickness of Wafers with Different Chemistries Introduction:  Silicon wafers are ordinarily highly conductive and easy to measure with standard capacitive displacement sensors (See MTI's Proforma 300i). Measuring the thickness of GaAs wafers that have high bulk resistivity (>10k Ohm/cm) is a little more difficult because the wafers act as non-conductive insulators in a capacitive sensor's measuring field. Fortunately, MTI has a solution to this problem. Solution:  It’s possible to measure the thickness and TTV of high resistivity semiconducting [...]
Photolithography Using Capacitance Sensors
Photolithography Using Capacitance Sensors Semiconductor Photolithography Using Capacitance Sensors Positioning Description When it comes to photolithography, how accurate are our sensors? Accurate enough to measure this: ​   Photo by D. Carr and H. Craighead, Cornell The world's smallest guitar is 10 micrometers long -- about the size of a single cell -- with six strings each about 50 nanometers, or 100 atoms, wide. Made by Cornell University researchers from crystalline silicon, it demonstrates a new technology for a new generation of electromechanical devices. Even the world’s smallest guitar’s 2 [...]

Case-In-Point: Step Height Measurement (Thickness) of Copper Foil or EV Battery Film on a Roller Rig
Step Height Measurement (Thickness) of Copper Foil or EV Battery Film on a Roller Rig Leverage MTI Instruments’ digital Accumeasure system to measure the thickness of the material used as anode and cathode plates in rechargeable Li-Ion battery cells Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement. Introduction [...]
New Video from MTI! Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing
Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing This animation demonstrates how Accumeasure with capacitance probes can be used as a solution to measure and control conductive film thickness in a production line where these measurements can be fed back to a controller which adjusts the roller(s) to increase or decrease the gap to keep the film’s thickness within specification. The MTI Instruments Capacitive system has greater than 100 nm resolution and 1um accuracy. This solution is appropriate for measuring the following: EV battery plate thickness Non-woven conductive material thickness Conductive film thickness Roll-to-roll conductive [...]
