EUV lithography machines purchased by TSMC may contain backdoors

It is reported that the EUV lithography machines purchased by TSMC from ASML may have backdoors that can be remotely locked when necessary. When the Dutch communicated with ASML about the lithography machine, the person in charge said that they were able to remotely control chip manufacturing equipment. This may mean that ASML has inherited the tradition of leaving backdoors in European and American companies, and this information may be used by the United States to cause the situation to get out of control. ASML has not concealed this, and there may be a big problem behind it.
