Definitions
- the present invention quartz, PZT (lead zirconate titanate), and processed into an arbitrary shape of the piezoelectric material such as LiNbO 3, control of the ultrasonic vibration, about the processing method which enables an improvement in vibration characteristics.
- Piezoelectric elements are used in a wide range of fields, such as oscillation sources for reference frequencies and clocks for electronic and electrical equipment, and are designed to be thinner for higher performance in information processing and transmission, and lens shapes for higher quality. Research on processing methods is under development.
- Japanese Patent Application Laid-Open No. 2002-368572 also discloses a method of performing dry etching after forming a profile close to the final target as one form of concave surface processing.
- the surface of the piezoelectric material is polished with a polishing cloth attached to the surface plate, but the crystal of the piezoelectric material is easily damaged.
- concave processing it is easy to obtain a high Q value by increasing the frequency by reducing the thickness of the layer and reducing the support loss, but it is difficult to form a three-dimensional shape, so it is difficult to distribute a large mass in the center of the vibrator. As a result, the vibration tends to be unstable with respect to the mass load. Disclosure of the invention
- the present invention provides a mask having a film thickness distribution corresponding to a target shape on a surface of a piezoelectric material (workpiece) and then dry-etches the mask so that a large area can be obtained.
- the objective is to obtain a piezoelectric material that has been processed into a three-dimensional shape with high precision, with excellent compatibility, ultra-miniaturization, integration, and flexibility in processing.
- a mask formed from a material having a different processing speed from that of the piezoelectric material is provided on the surface to be processed of the piezoelectric material, and the patterned mask material is heated and melted, and a precision die compression is performed.
- a predetermined film thickness distribution is given to the mask.
- a thin film for amplifying the processing speed ratio may be interposed at the interface between the piezoelectric material and the mask.
- the piezoelectric material provided with the mask is dry-etched, the piezoelectric material is processed into a shape following the thickness distribution of the mask. After the mask and the surface layer of the piezoelectric material are etched away using a gas composition with low selectivity at the beginning of dry etching, if the gas composition is switched to a gas composition with high selectivity for piezoelectric material, the film thickness distribution of the mask will change. The piezoelectric material is processed into the amplified three-dimensional shape.
- FIG. 1 is a flowchart of a process for three-dimensionally processing a piezoelectric material.
- the dry-etched piezoelectric material is processed into a three-dimensional shape reflecting the thickness distribution of the mask.
- dry etching is performed by selecting the mask material in relation to the piezoelectric material and adjusting the acceleration ratio of the piezoelectric material and the mask, or switching from a gas composition with low reactivity to a gas composition with high selectivity for piezoelectric materials. It can also be processed into a three-dimensional shape with an amplified mask thickness distribution. Even a piezoelectric material with a large area is complex and easy to process into any shape.

- a photoresist is applied to the piezoelectric material substrate 11, and then the resist film is exposed and developed under a condition in which the amount of light applied to the periphery is smaller than that in the center.
- the mask 14 can be shaped into a mask 14 having a film thickness distribution that becomes thinner from the central part to the peripheral part of the thick film. Since the etching rate of the photoresist mask 14 is generally lower than that of the piezoelectric material (substrate 11 to be processed), the irregularities formed by dry etching under normal conditions become shallower.
- a low-melting inorganic metal-ceramic such as tin, low-melting glass, or frit is reflowed to obtain a mask 14 having a lower processing speed than the substrate 11 to be processed. (Fig. 1B).
- the mask 14 may be laminated on the photoresist mask 13.
- a method is also possible in which a precision mold 15 previously formed on another substrate is pressed against the mask 13 and shaped into a mask 14 with a controlled film thickness distribution (Fig. 1C).
- a precision mold 15 it is preferable to spread a release paper 16 on the working surface of the precision mold 15 facing the mask 13 to facilitate separation of the precision mold 15 from the shaped mask 1.
- the mask 14 is formed into a mask 14 having a film thickness distribution that becomes gradually thinner from the thick central part to the peripheral part.
- the three-dimensional unevenness transferred to the processing target substrate 11 is also controlled by adjusting the processing speed ratio between the processing target substrate 11 and the mask 14.
- a PFC parameter
- a source of radicals or the like that selectively process or weaken the substrate 11 to be processed.
- the processing speed ratio can be controlled by changing the ratio between the selective reactive gas and the non-selective gas. Alternatively, the processing speed ratio is also controlled by the input power of plasma generation.
- the gas composition is switched from a gas composition with a large amount of non-selective gas to a gas composition with a large quantity of selective reactive gas.
- the film thickness distribution of the mask 14 is transferred to the substrate 11 to be processed.
- the target substrate 11 is preferentially etched. As a result, the substrate 11 can be processed into a three-dimensional shape in which the film thickness distribution of the mask 14 is amplified.

- the height of the lens of the mask 14 was set to about 1 to 2 ⁇ , a piezoelectric element having greatly improved vibration characteristics was obtained, and the Q value was more than twice as high as that in the unprocessed state. In the manufactured piezoelectric element, the sub-vibration was reduced by almost an order of magnitude.
- a positive resist was applied by spin coating to form a resist film having a thickness of 4 ⁇ . After patterning the resist film into a convex shape, heat treatment was performed. In the heat treatment, the resist was reflowed into a lens shape by gradually increasing the heating temperature, whereby a mask 14 having a controlled film thickness distribution was obtained.

As the processing speed ratio and processing speed decreased, the boundary between the mask 14 and the quartz plate was shaped into a slope with a gentle slope.
- the fabricated piezoelectric element could be used as an element with suppressed suppression of resonance frequency due to the curved surface distribution provided at the center.
- the piezoelectric material substrate 11 provided with the mask 14 with the controlled film thickness distribution is dry-etched, it can be processed to the target three-dimensional shape with higher precision compared to conventional wet etching-mechanical polishing, and a large It is also easy to distribute the mass.
