Wafer backgrinding is the first step in semiconductor packaging, the process of encasing one or more discrete semiconductor devices or integrated circuits (IC) for protection. Known also as wafer thinning or wafer lapping, backgrinding reduces wafer thickness to allow stacking and high-density IC packaging.

Wafer grinding or backgrounding is the most popular method for thinning wafers. The dimension to which a wafer can be thinned depends heavily on the machine used, but most thin silicon wafers have around 50 micrometers thickness. Anything below that measurement put wafers at risk of suffering from reliability issues.

device wafers before dicing them into individual dies (chips) [8,9]. The expanding market of thin and flexible silicon chips such as those in smart cards and smart labels (RFID) demands more advanced back-grinding processes [10]. The grinding process referred in this paper is the vertical spindle surface grinding (a.k.a. wafer grinding) using ...

Like wafer testing, grinding and dicing systems are dominated by only 2 players - DISCO Corporation and Tokyo Seimitsu. In the 1960s, semiconductor silicon wafer was only 23mm in diameter, and 275 microns in thickness. Following the development of larger silicon ingots to match the increase demand of chips and cost reduction, wafer diameter ...

In order to increase the yields of thin wafer grinding on existing and new machine tools, we offer state of the art technology wheels. Coarse Grind. Selecting a proper coarse grind wheel becomes very important for thin wafer grinding. If the sub surface damages left behind by the coarse wheels are not completely removed with the fine grind step ...

Backgrinding is a necessary process step to reduce wafer thickness prior to dicing and final assembly. By utilizing fully automated grinders staffed by highly qualified engineers, GDSI's grinding procedures produce unsurpassed precision and repeatability. Capabilities Individual chip grinding Wafer rounds up to 12" or 300MM

A method of grinding a semiconductor using a grinding machine having a chuck table for holding a semiconductor and a grinding means for grinding the top surface of a semiconductor placed on the chuck table, comprising the step of holding the ground semiconductor wafer carried out from the chuck table after grinding by means of a wafer holding tray.

TAIKO is a DISCO developed wafer back grinding method. By enabling an outer support ring to the wafer (the TAIKO ring, Japanese for drum), back grinding is performed on the inner circular area of the wafer, while leaving an edge of a few millimeters unprocessed. Taiko simplifies thin wafer handling and lowers warpage.
