By this, the authors mean how efficiently a product serves it purpose for the predicted period. The article claims that predicting the reliability of a product earlier is important since it helps in detection of aspects such as possible failure or decrease in life cycle. This is crucial since it ensures that the material selected for manufacture of the product is appropriate reducing inspection as well as impromptu maintenance. When making predictions, it is important to consider the environment to which the product will be exposed. This is because the lifecycle may change with environment.
Mishra, Pecht, and Goodman (1) list the objectives of reliability prediction as reducing output drawbacks, enhancing maintenance, ensuring that the equipment remains effective, increasing profitability and enable designing of future products that are safer and with lesser failures. The article claims that advancement in technology has increased guarantee and liability of product letdown. This has led to increased product reliability. However, the authors argue that increasing function ability of products such as gate oxide might lead to neglect for reliability.
The article posits, “A reliability prediction for a product is dependent on its structural architecture, material properties, fabrication process, and the life cycle environment” (Mishra, Pecht, and Goodman 2). This is because products manufactured from same production line vary in material properties. Variation in material properties during manufacture of semiconductor devices may lead to altered reliability, which affects functioning ability in different environments.
For semiconductor devices, the product life cycle is the expected severity and the load conditions such as temperature, pressure, humidity, dust, electromagnetic radiation levels and the environment. The factors and other like acoustic levels, sand,
