Wafer scribing machine for chip processing

Abstract

The invention relates to a wafer scribing machine for chip processing, which comprises a bottom plate, a scribing device, a workbench, a cooling mechanism and two cleaning mechanisms, wherein each cleaning mechanism comprises a fixed box, a fixed column, an air cylinder, a piston, an air inlet pipe, an air outlet pipe, a filter screen, an oiling assembly, a fixed block, a driving block, a connecting rope and two air cylinders; wherein the oiling assembly comprises an oiling box, a driving plate, a driving rod, a power rod, two first springs and two oiling units, the cooling mechanism comprisesa water tank, a water inlet pipe, a water spraying pipe, a supporting box, two water squeezing assemblies and two supporting rods, and each water squeezing assembly comprises a moving plate and two limiting units. According to the wafer scribing machine, through the cleaning mechanisms, the impurity removing function is achieved, the friction force between the scribing device and the wafer is prevented from being increased due to adhesion of chippings, so that the scribing work is prevented from being influenced, the scribing quality is improved, the function of cooling the scribing device isachieved through the cooling mechanism, and the scribing device is prevented from being damaged due to overheating.

Description

technical field [0001] The invention relates to the field of chips, in particular to a wafer dicing machine for chip processing. Background technique [0002] Wafer dicing is an essential process in the semiconductor chip manufacturing process. The whole wafer of the finished chip is divided into single chips according to the chip size, which is called wafer dicing. [0003] When the existing wafer dicing machine is dicing the wafer, the debris generated is easy to adhere to the wafer, which will increase the friction between the wafer and the dicing device, thereby reducing the accuracy of the division. Not only that, when the existing wafer dicing machine is working, because the dicing on the dicing device rotates at a high speed, the temperature of the dicing itself is relatively high. If it is not dissipated in time, the consumption of the dicing will be accelerated. The service life of the chip increases, thereby increasing the damage probability of the dicing chip and...

[0003] When the existing wafer dicing machine is dicing the wafer, the debris generated is easy to adhere to the wafer, which will increase the friction between the wafer and the dicing device, thereby reducing the accuracy of the division. Not only that, when the existing wafer dicing machine is working, because the dicing on the dicing device rotates at a high speed, the temperature of the dicing itself is relatively high. If it is not dissipated in time, the consumption of the dicing will be accelerated. The service life of the chip increases the probability of damage to the dicing chip and reduces the reliability of the existing wafer dicing machine
