Description
Technical Field
The invention belongs to the technical field of wafer processing equipment, and particularly relates to an etching machine with an automatic cup pouring function.
Background
Quartz wafers are the core components of quartz crystal resonators and oscillators. In the processing of quartz wafers, frequency is a key index parameter. The frequency and thickness of a quartz wafer are inversely related, i.e., the frequency is higher the thinner the wafer. For example, a thickness of about 0.08mm for 20MHz and about 0.04mm for 40MHz.
The thickness of the quartz wafer is processed by two methods, namely grinding and etching. Typically, etching is a process of final thickness (i.e., frequency).
The chemical component of the quartz wafer is silicon dioxide, and the chemical component can be commonly hydrofluoric acid or ammonium bifluoride solution which is called as etching solution.
During the processing of quartz wafers, it is necessary to finally achieve a narrow frequency range, for example 20100 + -100 KHz. If all wafers are etched together, the frequency concentration is not as desired. This requires measuring the frequency and dividing the frequency into cups, for example, each cup has a frequency range of 10KHz, before etching, and then pouring the cups into the etching solution at regular time intervals, sequentially from low to high, so that each cup of wafers is etched to the same frequency. This process we call "inverted cup corrosion". In this process, the frequency dispersion per cup will become large, and the frequency of each cup will vary, but the target dispersion of 100KHz can generally be achieved.
Therefore, wafer etching requires a machine, which we call an etcher. There are typically two tanks in the etcher: one is an etching tank which is used for containing ammonium bifluoride etching solution for etching the wafer; the other is a cleaning tank for holding clear water, and after the wafer is corroded, the wafer is put into the clear water to stop corrosion. According to the prior art, the inverted cup corrosion is all manual operation. Specifically, manually calculating the pouring interval time of two adjacent cups according to the corrosion rate of the corrosion solution and the frequency interval of each cup, and pouring each cup of wafers into the corrosion solution one by one according to a fixed time interval; the manual operation has the following disadvantages:
the manual operation process needs about 10 to 30 minutes, which consumes manpower;
(ii) human labor may have time errors resulting in a reduced frequency concentration.
