  4. The TAIKO process is the name of a wafer back grinding process that uses a new grinding method developed by DISCO. This method is different to conventional back grinding. When grinding the wafer, the TAIKO process leaves an edge (approximately 2 mm) on the outer most circumference of the wafer and thin grinds only the inner circumference. By using this method, it lowers the risk of thin wafer ...

  5. Wafer Backgrind Wafer Backgrind is the process of grinding the backside of the wafer to the correct wafer thickness prior to assembly. It is also referred to as 'wafer thinning.' Wafer backgrinding has not always been necessary, but the drive to make packages thinner and thinner has made it indispensable.

  6.  · The Process. The process of thinning wafers involves using a mechanical grinding wheel, chemical slurry, and IR equipment- to help you measure the thickness. A classic grinding process would involve three stages: coarse grinding, fine grinding, and polishing. For example, you want to grind a silicon wafer from 725 micrometers to 50 micrometers.

  9.  · Especially, key process for controlling chip-shift is back grinding process. In order to control the chip-shift, 1st key point is Young's modulus of base film. Elongation of BG tape in laminating process causes chip-shift, so we have optimized base film which can be control chip-shift.

  10.  · Process Considerations. The grinding process involves a lot of unusual considerations you wouldn't ordinarily think of. "On today's cylindrical grinding there is a lot of post-process gaging, where the customer wants to measure the part after it leaves a cell and send that data back to the machine," Berman said.

  13. Back grinding is a process that removes silicon from the back surface of a wafer. Silicon Valley Microelectronics provides grinding on our own substrates or on customer supplied wafers. We process bare and device patterned wafers with high yield and offer wafer thinning to customer specifications. SVM Wafer Back Grinding Capabilities:

  14. Fine grinding of silicon wafers requires high predictability and consistency, which requires the grinding wheel to possess self-dressing ability, i.e., after initial truing, the wheel should not need any periodic dressing by external means. In other words, there should be "a perfect equilibrium

  15. This study investigates warping of silicon wafers in ultra-precision grinding-based back-thinning process. By analyzing the interactions between the wafer and the vacuum chuck, together with the ...

  16. 7. Turn the machine on again. While the wheel is spinning, lower the grinding wheel down in the Z direction until it makes a small plume of dust. 8. Once the small plume of dust has been made, make one pass back and forward along the Y-axis. Stop the machine when the dresser has made on pass back …

  17. process which leaves the back-side silicon under the CMOS metal and oxide layers, and improves the uniformity of the back-side silicon using back-side grinding. The Si-CMOS-MEMS process includes a grinding process followed by a bonding process and conventional post-CMOS etch. A Si-CMOS-MEMS accelerometer is used to
