Therefore, during the process, the resolution and precise alignment factors are taken into account to prevent circuit and device failure.
Semiconductor materials possess electrical and physical properties that allow the unique functions of semiconductor devices and circuits [9].
These properties are examined along with the basics of atoms, electrical classification of solids, and intrinsic and doped semiconductors.
Factors like resist thickness and developer concentration are almost constant for both device features.
Based in the mechanical properties of the device structure, major factors could be affected.

The purpose was to perform local alloying in the form of surface network of four tracks (each two are parallel and perpendicular to the other two) to produce a good thermal and electrical properties bulk material with reasonable surface hardness properties.
The morphological features of the subsurface laser treated layers and their mechanical properties (microhardness) have been studied on oblique sections through the laser fused tracks.
Laser treatment improves the surface properties of materials in many ways.
Better properties can be achieved such as hardness, heat stability and wear resistance.
However, the results of these experiments showed no improving in cutting properties [2].

Torque measurement based on the SAW technology has advantages of high measuring accuracy, fast response and passive wireless property, overcoming disadvantages of strain gauge measurement, grating measurement, etc.
There are many factors that affect the strain transfer.
By studying the relationship between these factors and strain transfer, we will provide a theoretical basis for optimizing the design of sensor structure.

Although the effect of the reinforcing phase on the mechanical properties of the amorphous matrix at room temperature has been extensively studied in recent years [7], little attention has been given to the deformation of BMG composites in the supercooled liquid region.
There exist various models to elucidate the mechanical deformation behavior at high temperature of amorphous alloy.
The pre-exponential factor 0ε& ranges from 1x10 -3s-1 to 3x10 -3s-1.
Larger initial void size (or, equivalently, a larger initial void fraction) can weaken the mechanical properties of the BMG composite.

Because traditional resonant linear piezoelectric motors work in the unstable resonance state, the process error, frictional temperature rise and other factors will affect the stability and the mechanical properties of these motors [6].
(2) Fig. 2 Displacement amplification of drive foot Let lever magnification factor is γ.
Thus: (5) Where, γ and γ’ is the displacement amplification factors of x-axis and y-axis respectively and both are constants greater than 1. xc and yc is the displacement of point C in x direction and in y direction.
The displacement of the Y-axis was inversely proportional to tangent value of θ, i.e. the less the angle θ is, the larger the magnification factor is.
Then the maximum magnification factor can be obtained when H is 0.8mm and θ is 12°

Classification And Organization Of Quality Information In The Remanufacturing Industry Process quality is an important factor affecting the quality of products, so the quality information of the remanufacturing industry includes product quality information and process quality information, which insisted of the quality standards information and the quality assessment information[4].
The module rolls in providing a clear remanufacturing product structure, and building up association with remanufacturing process management module. 2)Remanufacturing process management module includes all process information of affecting the final remanufacturing product quality.
Through effect factors analysis and comparison of the remanufacturing product quality, you can find the key processes; key influencing factors and the optimal level combination by fully use of fishbone diagrams, Pareto, and multivariate analysis tools, in accordance with this combination, so as to achieve the stability improvement of product quality[8]. 3)Quality tool integration module provides a variety of quality tools to support process improvement.
