1. Customer Benefits: High-quality semiconductor manufacturing and cost reduction
Accurate temperature control in semiconductor manufacturing directly benefits your business greatly. First, it improves product quality. For example, even a slight temperature error during the heat treatment process of silicon wafers can adversely affect the electrical characteristic of the semiconductor, potentially resulting in defective products. Accurate temperature control improves yield and enables a stable supply of high-quality semiconductors.
Secondly, it also contributes to reducing production costs. Reducing defective products reduces the costs of materials, time, and energy required for replay. Furthermore, stabilizing the process reduces unexpected problems and minimizes downtime. As a result, our customers are able to provide the market with high-quality semiconductors at competitive prices.
2. Re-examination: The importance of temperature measurement in semiconductor manufacturing
Semiconductors device undergo a wide variety of heat treatments process during their production. In these process such as crystal growth, diffusion, deposition, and annealing, exacting temperatures control are essential to alter the physical properties of the material and to form specific structure
Temperature control during the diffusion process
In the diffusion process, when dopants are introduced into the semiconductor substrate, if the temperature is too high, the dopants will penetrate too deeply or spread laterally, which can reduce device performance. Conversely, if the temperature is too low, the dopants will not diffuse sufficiently and the desired characteristic will not be achieved.
Temperature control in the film formation process
During the film deposition process, the substrate temperature affects the crystallinity, density, and stress of the film. If the film is not deposited at an appropriate temperature, the film's adhesion and electrical characteristic will be impaired, affecting the reliability and lifespan of device.
In this way, even slight deviations from the optimum temperature at each process have a direct impact on semiconductor performance, reliability, and ultimately yield.
3. The importance of calibration: Why do thermometers need to be calibrated?
No matter how high-performance a thermometer is, its indicated value will deviate from the true value over time. Calibration is the process of correcting this deviation and ensuring the accuracy of the measuring instrument. There are several reasons why calibration is particularly important in semiconductor manufacturing.
Ensuring international traceability
Calibration is carried out using reference equipment based on national and international standards, ensuring that the temperature measured is based on a common standard that can be used anywhere in the world.
Stabilizing and repeatability manufacturing processes
Regular calibration ensures that your thermometer always shows accurate values, minimizing fluctuations in temperature conditions during daily production and enabling you to consistently manufacture products of consistent quality.
Quality management system support
Many quality management systems (such as ISO 9001) require calibration of measuring equipment. This is the basis for a company to guarantee the quality of its products, and proper calibration helps companies respond to audits and gain customer trust.
Fourth, early detection of malfunction and preventive maintenance. During the calibration process, it may be possible to detect signs of deterioration or malfunction of the thermometer. This will prevent production line shutdowns due to sudden malfunction and enable planned maintenance.
