Introduction
Over the past decade, many important technological advances have provided us with the tools and materials needed to construct biosensor devices.
Besides some analytical performance advantages, nanotechnology has bring biosensor the possibility for construction of biosensor arrays for high throughput parallel measurements, increase sensitivity and selectivity by incorporating nanomaterial and the possibility for integration of biosensors with microfluidics for construction of lab-on-a-chip devices [2,3].Nanotechnology is defined as the study of synthesis, properties and application of structures and materials having at least one critical dimension on the scale of less than 100 nm [3].For these Nanobiosensor to reach their potential, they must designed and fabricated with conformity of significant parameters like dimension, material on which selectivity and sensitivity of a device are qualified.
In photolithography, the critical dimension can be limited by many aspect of the process including hardware, materials and processing consideration [6].

Sensing unit is based on the piezoelectric effect, and utilizes the principle of sound waves near the surface of the particular piezoelectric material, that the energy of the wave decay exponentially in the direction away from the surface of the piezoelectric material and more than 95% of the energy is left in the material near the surface.
Therefore any changes of the characteristics of the surface piezoelectric material that is the changes of the wave propagation will cause corresponding changes of the wave velocity, amplitude and frequency; we can obtain the variation in characteristic of piezoelectric material by detecting the changes of the wave frequency (∆f).
There is a direct correlation between the characteristics of the piezoelectric material and the environment temperature, humidity, gas concentration, pressure, torque, etc Qualities and properties of the piezoelectric material affect the performance and uses of the SAW sensors directly.
So we chose the quartz material as the resonant device to make the sensing unit because of its cheaper cost and relatively mature production technology.

We choose nickel-based superalloy GH4169 as the material of sealing ring[1,2], working temperature can reach to 600 ℃.
Under high temperature, the strength of the material is still very good, its oxidation resistance, fatigue, fracture toughness, plastic and other comprehensive performance are very good also, the basic mechanical properties parameters are shown in Table 1[3].
In the local high stress area of the sealing ring, material may occur plastic deformation, and present a nonlinear characteristics of the material.

For the oxygen-free copper TU1 material, surface residual stress mainly due to plastic deformation effects belonging to mechanical stress[3].
First, we take the aging treatment for material.
As shown in Fig.4, the basic principle of “equilateral milling strategy” is that using side edge of the cutter to remove the material of both sides evenly offset the residual stress generated due to cutting forces and material removal.
The fixture tooling using cast iron material because its thermal expansion coefficient is small can be processed to a higher accuracy.
