15th Rep. COVID-19 Infected Employee at Overseas Affiliate Office

DISCO has confirmed that two Processing engineers in the California Office in the overseas affiliate DISCO HI-TEC AMERICA, INC. tested positive for COVID-19 on July 20 and 26 (Monday and Sunday, California time).
Employees at the California Office have generally been working from home since March 16 (Monday) in accordance with jurisdictional instruction. However, the Processing Service Department, of which the employees were members, handles processing of next-generation materials for R&D departments for semiconductor and electrical component manufacturers mainly based domestically in the U.S., and also conducts developmental work in the fields of 5G, IoT, aerospace, and aviation. DISCO HI-TEC AMERICA received a formal request from a customer who acquired an Essential Service Certificate, and for that reason, those performing the processing were commuting to the office with the permission of the government.
The chain of events and how the situation was handled are as follows.

Thurthday, July 16
  • Employee A had a fever (39℃) that morning. He visited a doctor and took a PCR test instead of going in to the office.
  • The entire California office was shut down, and all employees in the Processing Service Department who had planned to go in to the office stayed home.
  • Employee hearings were conducted in accordance with CDC standards. Confirmed that Employee B had close contact with Employee A (used the same car).
Monday, July 20
  • The PCR test results for Employee A came back positive.
  • The entire California office was disinfected by a professional contractor in accordance with CDC regulations.
Wednesday, July 22
  • The Processing Service Division in the California Office resumed operations.
Sunday, July 26
  • The PCR test results for Employee B came back positive.

Moreover, close contact between Employee C and Employee B, who also shared a car, was confirmed separately. Employee C took the PCR test and the results are pending. Therefore, the Processing Service Division of the California Office is currently operating with the exception of the three employees stated above (two PCR infected and one with internal close contact).

DISCO will continue carrying out the thorough infection prevention measures that have been implemented group-wide and will work hard to provide a stable supply of products and solutions.

Infection Prevention for Employees and Preventative Measures for Internal Infection

The following measures are being implemented at the Hiroshima Offices (Kure Plant and Kuwabata Plant), DISCO’s major production bases.

Commuting

From the point of view of infection prevention, commuting by car is recommended for employees who normally use public transportation. In addition, designated commuter busses have been chartered at the Kure plant in Hiroshima to transport employees.

Internal Infection Prevention

In order to prevent internal infection pathways at both plants, the Precision Processing Tool Manufacturing Division and other Divisions have separated walking paths and limited use of internal facilities and welfare facilities, including the employee entrance, bathrooms, conference rooms, and cafeteria.

Moreover, the following measures have been implemented for the entire company, including the Hiroshima Office.

Before Leaving Home

In addition to body temperature measurement and internal system registration already being conducted, a system for contacting nurses in case of health problems by filling out an interview sheet has been introduced. This will make it possible to detect infections early.

Commuting

Not only is wearing a mask required at all times while using public transportation, but employees have been instructed to commute at different times to reduce the risk of infection.

Entering the Office

Employees must sanitize their hands and replace their masks with a new one to enter the office. Customers suspected of being infected are not authorized to visit the company. Not only do we check visitors’ overseas travel histories and health conditions, but we also measure body temperature and require visitors to sanitize their hands and wear a new mask when visiting.

Working and Lunch

Wearing a mask is mandatory during work and communication among employees and customers without masks is prohibited.

Internal Sanitization

The frequency of periodic cleaning of bathrooms, elevators, and handrails has been increased.

Overseas Travel

Overseas travel is prohibited for work, and personal overseas travel is discouraged. Employees who have traveled overseas must work from home for fourteen days after returning. They may then return to the office if they show no symptoms.

Miscellaneous

In order to prevent an employee’s family from being a source of infection, all employees are required to submit an “Action Plan to Prevent Infection at Home.” The BCM department compiles information on virus risks to make explaining the situation to your family easier.

In Case of Infection

The infected employee will be required to take a leave of absence, and theirs and neighboring departments will be sanitized. Though we believe it is possible to control secondary infection and internal close contact by implementing the above measures, if there is any doubt, employees will be instructed to work from home for fourteen days.
In addition, an environment in which employees feel safe to take days off has been cultivated by changing the attendance system, which includes being able to use expired PTO days.

In order to fulfill our obligation to supply products to customers, measures will continue to be implemented to correspond with the situation.

5th Rep. Production Status of DISCO Product

This is a follow-up announcement regarding the production status of DISCO products in response to the spread of the novel coronavirus (COVID-19).

Precision Processing Tools

As stated in the fourth report on February 13, because DISCO keeps at least a six-month supply of raw materials in stock for standard production, production and shipment are currently unaffected. By continually replenishing the raw material stock, DISCO will maintain a system that enables production without a reduction in stock.

Precision Processing Equipment

It has been confirmed that all equipment scheduled for shipment in March and April will be produced and shipped as planned.
After May, we will continue to monitor the situation as some component parts are produced by suppliers in China, depending on the specification. In addition, it was confirmed that there are no production delays at the relevant suppliers after resuming operation on Monday, February 10, and there are parts in stock either in China or Japan. If the situation persists and there is concern regarding parts supply, we will respond by switching to replacement parts, etc., to ensure undelayed production and shipment.

4th Rep. Production status of DISCO product

In response to the spread of the novel coronavirus, this is an announcement regarding the production status of DISCO products.

Precision Processing Tool

Because DISCO keeps a 6-month supply of raw materials in stock as part of our BCM (business continuity management) measures, production and shipment are currently unaffected. We are also continuously replenishing this stock to ensure a constant supply to maintain our production and shipment schedule.

Precision Processing Equipment

Equipment scheduled for shipment during February 2020 will be produced and shipped without any delay. During and after March, standard specification equipment can be produced and shipped as scheduled. However, because some suppliers of component parts base production in China, depending on the specification, there are some concerns regarding future supply. The aforementioned suppliers resumed operations on Monday, February 10, 2020, but it has been confirmed that the operation rate has fallen due to factors such as remote work. If the situation becomes prolonged, DISCO will proceed with measures such as switching to alternative suppliers with whom DISCO has built relationships and design changes to ensure stable production and shipment.

Status updates will be provided on the DISCO website as the situation develops.
