What Is a Stress Analyzer?
A stress analyzer is an instrument used to determine what kind of stress is being applied to a material.
There are two types of stress: compressive stress and tensile stress, and if either stress is too high, it can lead to damage or film peeling. Stress changes during heat treatment and film deposition, so it must be measured and controlled to maintain uniform quality.
There are several methods to measure stress, including measurement of radius of curvature, measurement of birefringence, and the use of X-ray diffraction. Each method has its strengths and weaknesses, so the appropriate stress analyzer is selected for each application.
Uses of Stress Analyzers
Stress analyzers are indispensable in fields where stress plays an important role, such as film deposition and glass reinforcement.
In the semiconductor industry, various thin films are deposited on silicon wafers. Stress analyzers are used to determine if such an abnormality has occurred.
Since strengthening glass increases its strength by increasing the compressive stress near the surface, stress measurements are also taken after the strengthening process.
Principle of Stress Analyzers
Stress indicates the force exerted on a part of an object, for example, in glass, the force of expansion or contraction of the glass surface, which is zero for the entire object.
When a thin film is formed on a silicon wafer as a substrate, the wafer is pulled by the stress as the formed film tries to contract, causing the wafer to bend. In other words, the radius of curvature of the wafer changes before and after the film is deposited, and the stress is calculated from this change. In this case, the radius of curvature is obtained by scanning the wafer with a laser.
When glass is strengthened, stress can also be calculated from the difference in radius of curvature before and after strengthening, but since glass is transparent, stress can be calculated by measuring birefringence. When stress is applied, the refractive index will differ depending on the direction of the stress. This is called birefringence. When light enters glass under high stress, it is refracted and interferes in a more complex manner than when the glass is not stressed.
In the case of crystals, light diffraction occurs, so stress measurements can be made using X-ray diffraction. The stressed area is subjected to stress-induced expansion and contraction of the interstitial lattice, and this expansion and contraction is measured. The advantage of this method is that it does not require a flat surface since it uses X-ray diffraction, and can be performed even on complex shapes.
Residual Stress Measurement
Residual stress is the "force" remaining in the inner part of a material element or structure after the "force" applied to the material has been removed. When a mechanical or thermal load is applied to a material, the material tries to return to an equilibrium state. At that time, residual stresses occur inside the material element. Residual stresses can also occur when a similar load is applied while the material is moving or operating.
Residual stress can be measured in a variety of ways, but there are few methods that provide quantitative stress values.
X-ray analysis can be used to measure materials produced by all crystalline materials. It also offers the following advantages:
- Both surface and internal measurements are possible
- High-speed measurement is possible, e.g., on the production line
- Non-destructive and relatively low cost
