What is Downtime and What Are Its Types in the Semiconductor Industry?
For any manufacturing industry like semiconductors, the duration when the manufacturing process or operational activities stop is known as downtime. There are two significant types of downtime:
Planned Downtime
When a manufacturing company is scheduling a halt to stop its operational activities like productions for a scheduled maintenance, manufacturing changes, or upgrades is known as planned downtime. Though this downtime still results in monetary loss, the priority is to manage the machinery maintenance and changeover of products as they remain within the budgeted timeframe.
Unplanned Downtime
Unplanned downtime is an unexpected interruption that disrupts the functioning of production and operational activities. It occurs without any prior warning and persists for an unpredictable period, which can create a halt in production and result in a loss of revenue.

Unplanned downtime often results from hardware failure. This may be due to a lack of maintenance, legacy systems security risks, or the continuous use of outdated legacy systems that are incompatible with modern production technologies. Due to unplanned downtime, semiconductor manufacturers lose revenue for every minute the machine is not producing.
Real-World Downtime Examples in Semiconductor Industry
Here are some real-world examples of semiconductor manufacturers who faced downtime, resulting in revenue loss.
- Toshiba and Western Digital: In July 2019, Toshiba and WD plants in Japan experienced a 13-minute power outage. This affected their manufacturing facilities, halting the production of their NAND flash memory and impacting their global supply.
- Renesas Electronics Chip Factory: Renesas Electronics is a renowned semiconductor manufacturer known for its automobile chips. Toyota, Honda, and Nissan are some of its well-known clients. Due to a fire incident in one of the company’s cleaning rooms in Naka City, Japan, they had to halt production, affecting the global chip supply.
- Samsung Electronics: In 2020, Samsung Electronics faced unplanned downtime in its Hwaseong factory due to a one-minute power outage, which took around three days to recover. Also, in 2018, the Pyeongtaek factory faced a 30-minute blackout, resulting in a loss of 50 billion won ($43.3 million).
How to Calculate Downtime True Cost in the Semiconductor Manufacturing Industry?
The impact of downtime on employees and productivity can calculate the true cost of downtime in the semiconductor manufacturing industry. For employee downtime, calculations of wages and overtime are included, while for productivity calculations, orders lost that have affected sales and the loss of any client are considered. By combining these factors, semiconductor manufacturers can easily calculate the estimated fiscal figure due to unexpected interruptions.

There is a direct correlation between the cost related to employees impacted by the downtime and the decline in production.
- For the actual loss calculation, determine how many hours per day production has taken place compared to the average number of units produced with the hours of unplanned downtime.
- Now, divide the average units produced without any interruption during the day.

How Do Outdated Legacy Systems Result in Downtime in the Semiconductor Industry?
Outdated legacy systems are the aging hardware that requires regular maintenance, while their manufacturers no longer support some of the vintage hardware. Here are some common outdated legacy systems challenges due to downtime:

Cybersecurity Risks and Vulnerabilities
Outdated legacy systems are not updated and lack modern security measures, making them vulnerable to various security vulnerabilities, which can result in system failures and production halts.
Incompatibility Issues
Aging legacy hardware are incompatible with the latest technologies and create bottlenecks in production processes. Many semiconductor manufacturing industries are adopting smart manufacturing or Industry 4.0, which means integrating AI, data analytics, and IoT in their production for seamless operations and enhanced productivity. This limitation of aging hardware becomes more apparent, affecting overall operational efficiency.
Lack of Support
One of the significant challenges of aging hardware is the lack of assistance and support from their manufacturers (OEMs), which further drives the need for migration of legacy systems to modern, supported platforms. As the hardware and systems age, obtaining replacement parts becomes increasingly difficult. Also, with the rise in modern technology, getting skilled experts to work on legacy hardware is becoming tough, which also contributes to downtime.
Challenges Regarding Maintenance
Maintaining aging legacy hardware can be extremely challenging and expensive. Also, with a lack of vendor and manufacturer support, managing that hardware becomes increasingly difficult in case of wear and tear, resulting in unplanned downtime.
Regulatory Non-Compliance
Older legacy systems struggle to meet the latest industry regulations and standards. They are also vulnerable and more prone to data leaks and breaches, which can result in fines and legal penalties.
These issues often result in frequent system crashes, slow processing speeds, and compatibility issues with modern technologies, leading to unplanned downtime and revenue loss. Thus, reliance on outdated legacy systems ultimately compromises productivity and efficiency and inflates costs.
