Description
Technical Field
The utility model relates to the technical field of chip detection, in particular to a four-side detection device for a DFB chip.
Background
With the rapid development of semiconductor chips, industries and equipment related to semiconductor chips are also in a mature stage, and in the manufacturing process of chips, the appearance of the chips needs to be detected after the chips are cut, and the appearance detection of the chips is that of a whole-disc product, and the detection of the appearance of the chips is that of a single chip. The inspection of individual chips, i.e. the front and back sides and both sides of the chips, requires that the chips be individually removed from the wafer and placed in a platform for inspection and then moved to another empty wafer tray. The chip product comprises a primary ring, a secondary ring, an iron ring and a bare wafer, the common DFB products to be detected are generally two types of primary ring and secondary ring, and the current detection equipment is basically used for detecting the primary ring and secondary ring, namely the whole primary ring and secondary ring are placed on a platform to be detected, and then front or back detection is carried out.
At present, for the whole disc detection of primary and secondary ring wafer, although the detection efficiency is high, the appearance defect condition of new lotus root slice crystal grains can only be reflected from the front or back, for a DFB chip, we need to observe the side surface of the chip crystal grains so as to obtain the data in terms of the thickness of the chip crystal grains, such as the condition of the chip crystal grains on ridge waveguides and gold plating layers, which cannot be observed in the whole disc wafer detection, and for the two kinds of chip crystal grains with defects and no defects, we need to separate the two kinds of chip crystal grains and place the two kinds of chip crystal grains on different material discs in sequence, thereby realizing the effect of chip sorting.
In general, for four-side detection and sorting of single chip grains, a DFB chip four-side detection device needs to be designed to solve the above problems, and effectively meet the requirements of high-precision and high-efficiency production process for appearance detection of DFB chips.
