Embodiment Construction
[0022] The preparation method of this law invention comprises the following steps:
[0023] In the first step, referring to Figure 1(a), (b), apply a layer of ultraviolet photoresist with a thickness of 200nm on the single crystal silicon substrate by using the glue-spinning process;
[0024] In the second step, referring to Fig. 6 (a), (b), make an interdigital electrode mask according to the parameters of the interdigital electrode to be prepared, wherein the interdigital length is 10mm, the interdigital width is 1mm, and the interdigital spacing is 1mm. There are 4 pairs of interdigitated pairs; then use the interdigitated electrode mask as a cover to use ultraviolet (UV) photolithography to obtain photoresist interdigitated electrodes as shown in Figure 2 (a), (b).
[0025] In the third step, the photoresist layer obtained in the previous step is used as a cover, using C 4 f 8 : 180sccm (milliliters per minute), time: 10s; SF 6 : 100sccm (milliliters per minute), time: ...
