I need technology in which the IC will work at temperatures above 300 °C. For example, Fraunhofer makes chips at this temperature using Tungsten interconnect. Do foundries like TSMC or Globalfoundries have similar technology for fabricating high-temperature chips?

I'm looking for a chip like this. Can it be made with conventional foundries such as TSMC or GF ...? High temperature SOI CMOS technology and circuit realization for applications up to 300°C

I need technology like this: High Temperature Electronics

    \$\begingroup\$ Why must the IC work at temperatures above 300 C? Why can't you place the IC somewhere else or shield it from heat? \$\endgroup\$ Jul 31, 2019 at 7:11
  • \$\begingroup\$ IC is located next to a strong source of heat and cannot be shielded. \$\endgroup\$ Jul 31, 2019 at 7:13

    \$\begingroup\$ Do foundries like TSMC or Globalfoundries have similar technology for fabricating high-temperature chips? I would say that they don't but I could be wrong. This high temperature stuff looks to me like it is still in the research phase (Fraunhofer is a research institute not a commercial foundry like TSMC and GF). \$\endgroup\$ Jul 31, 2019 at 7:31

Honeywell SRAM HT6256.

The RAM provides guaranteed performance over the full -55 to +225°C temperature range. Typically, parts will operate up to +300°C for a year, with derated performance.

But I feel that this technology protected by many NDAs.

The "Prolonged 500 °C Operation of 100+ Transistor Silicon Carbide Integrated Circuits" article tells that:

This report describes more than 5000 hours of successful 500 °C operation of semiconductor integrated circuits (ICs) with more than 100 transistors.

"Ozark Integrated Circuits" reports that they can produce 600°C ICs with SiC transistors on aluminium substrate.

Also you may look at the "Honeywell's HTMOS™ High Temperature Electronics" article and the "Geothermal Technologies Program 2010" article.

Quoting from the link below:

The XI10 series is a partly depleted SOI high voltage technology. It is ideally suited for automotive and industrial applications operating at high temperatures up to 225 °C.

    \$\begingroup\$ Thanks for trying to help. Unfortunately this doesn't answer the original question, where the OP wanted to know about "technology in which the IC will work at temperatures above 300 °C". The technology described on your linked page "only" goes up to 225 °C. \$\endgroup\$
