Wafer Measurement – Ungrounded
Wafer Measurement - Ungrounded Semiconductor Wafer Measurement - Ungrounded Metrology Description MTI Instruments Inc. has developed a thickness measurement device that eliminates the effect of varying target conductivity. Called the Push-Pull probe, it’s a unique version of the AccumeasureTM amplifier series. This special design provides accurate surface information for wafer bow and warp. Bow is the deviation of the center point of the median surface of a free, un-clamped wafer from the median surface to the reference plane. Where, the reference plane is defined by three corners of equilateral triangle. This [...]

Wafer Thickness, Bow, Warp And TTV
Semiconductor Wafer Thickness, Bow, Warp And Ttv Surface Description Thickness Measurement ASTM F657: The distance through a wafer between corresponding points on the front and back surface. Thickness is expressed in microns or mils (thousandths of an inch). Total Thickness Variation (TTV) ASTM F657: The difference between the maximum and minimum values of thickness encountered during a scan pattern or series of point measurements. TTV is expressed in microns or mils (thousandths of an inch). Figure above shows a wafer placed between two non-contact measurement probes. By monitoring changes between the upper probe face [...]
Tape Cartridge Movement
Tape Cartridge Movement Semiconductor Tape Cartridge Movement Positioning Description Researchers are presently working on drives with track widths in the 5 to 1 micron region. For these small widths, tape wander, properly called Lateral Tape Movement (LTM), must be less than 1 micron. This is because the track following head always lags the moving target and produces a position error signal. If the position error signal gets to be larger than about 1/10 the track width, the track cannot be read. However, it follows that the smaller the LTM, the [...]

Wafer QA/QC After Slicing And Polishing
Wafer QA/QC After Slicing And Polishing Semiconductor Wafer Qa/Qc After Slicing And Polishing Surface Description Introduction:When wafers are sliced up with wire saws, they are measured to make sure they are within the specified thickness, with minimal bow, warp, and TTV. After initial measurement, they are sorted and sent for polishing. Since polishing removes material and smoothes out the rough surfaces they need to be measured again to ensure they meet thickness guidelines and quality standards. Solution:MTI Instruments manufactures multiple systems to perform thickness measurements. From semi automated Proforma 300SA to manual [...]

Height Gap Of Inkjet Printers
Height Gap Of Inkjet Printers Consumer Electronics Height Gap Of Inkjet Printers Positioning Description Introduction:  Inkjet printers require a certain distance between the inkjet print head and the paper. If the distance is set incorrectly, the printed images get blurry. Current state of the art printers have the print head nozzles built right into the bottom of the ink reservoir (B) as shown below. When the ink cartridge is installed in the printer, the inkjet nozzles (made out of silicon) essentially become a grounded target through the connections shown at [...]
