Abstract
Provided is a method for grinding silicon wafers by means of yellow cover paper. According to the method, the silicon wafers, a clamp, the yellow cover paper and a grinding device are adopted, the yellow cover paper is processed to be in a shape that the yellow cover paper can be embedded into the bottom of the clamp, the yellow cover paper is placed as a mat inside the bottom side of the clamp, then one silicon wafer is placed in the clamp, that is, the yellow cover paper is located between the bottom side of the clamp and the silicon wafer, and the silicon wafer can be ground through the grinding device after the silicon wafer is installed; after 5-7 silicon wafers are ground by the yellow cover paper, the yellow cover paper is taken out, and new yellow cover paper is placed as a mat in the clamp again. According to the method, the silicon wafers in the clamp are more stable in the grinding process; the yellow cover paper is adopted to replace traditional black adhesives or foam cotton or damping cloth, the silicon wafers are effectively prevented from being crushed, the surfaces of the silicon wafers are not prone to being damaged, the percent of pass of the ground silicon wafers is greatly improved, and cost of enterprises is lowered.
Description
Technical field
The present invention relates to optical element processing technique field, be specifically related to a kind of method of utilizing Calusena lansium paper grinding silicon chip.
Background technology
In recent years, along with scientific and technical progress and development, in the various optical systems for digital camera, video camera etc., often adopt silicon chip to be used for improving optical property and make optical system miniaturization.With it together, the apparatus and method that need a kind of grinding silicon chip.
In traditional process of lapping, conventionally adopt silicon chip to pack in specific fixture, and adopt the fixed form of gluing eyeglass, but not only time-consuming but also effort of this method of operating, be unfavorable for very much the carrying out of production line of enterprise.The fixed form that replaces subsequently this gluing; adopt pad to be arranged between silicon chip and fixture; conventionally the pad adopting is the form of black glue, foam or damping cloth; but adopt such pad; silicon chip often can cause the consequence of damaged surfaces to make the qualification rate of the silicon chip after grinding very low in process of lapping; cause certain wasting of resources, increased the cost of enterprise.
Therefore, the problems referred to above are the problems that should pay attention to and solve in the design and use process to lens grinding method.
Summary of the invention
For the problem of above-mentioned existence, the invention provides a kind of method of utilizing Calusena lansium paper grinding silicon chip.
Technical solution of the present invention is: a kind of method of utilizing Calusena lansium paper grinding silicon chip, comprise silicon chip, fixture, Calusena lansium paper and lapping device, the method comprises the following steps: the shape that Calusena lansium paper conversion is become can be embedded in to described clamp base, Calusena lansium paper washer is entered to bottom side in described fixture, again silicon chip is placed in to described fixture, be Calusena lansium paper between the bottom side and described silicon chip of described fixture, just can adopt lapping device to grind described silicon chip after installing; Described Calusena lansium paper, after grinding 5 ~ 7 silicon chips, takes out Calusena lansium paper, and new Calusena lansium paper is encased inside in fixture again.
Further improvement of the present invention is: described fixture adopts plastic-steel to make.
Further improvement of the present invention is: described Calusena lansium paper is thin soft type Calusena lansium paper, and the thickness of the Calusena lansium paper that the method adopts is 0.07 ~ 0.18mm.
A kind of method of utilizing Calusena lansium paper grinding silicon chip of the present invention, using the suitable Calusena lansium paper of cutting as pad pad the bottom at silicon chip, be positioned at fixture, after fixture installs, just can adopt lapping device to grind silicon chip.Ground silicon chip extracting, then put into silicon chip to be ground, after having ground 5 ~ 7 silicon chips, Calusena lansium paper is changed, be about to last silicon chip extracting, Calusena lansium paper after take out using, then put into new Calusena lansium paper, according to above-mentioned steps to needing the silicon chip grinding to grind below.
The invention has the beneficial effects as follows: the present invention adopts plastic-steel fixture, Calusena lansium paper washer is entered at fixture inner bottom part to place silicon chip again, the silicon chip that makes to be arranged in fixture can be more stable at process of lapping.And adopt Calusena lansium paper to substitute traditional black glue, foam or damping cloth, effectively prevent that silicon chip from being damaged by pressure, the surface of silicon chip is difficult for damaged, has greatly improved the qualification rate after silicon chip grinding, has reduced the cost of enterprise, is adapted to carrying out of enterprise's production line.
