Hi Bryant, this is very helpful, especially to those like me starting out in the field. In my opinion, it would be quite informative to get expected lifetimes of specific tools (perhaps even including models) as well. How long does a plasma etcher, or electron
beam lithography tool, generally last (for example)? </div>

<div>Hello All,<br>
<br>
Long time stalker, first time talker.<br>
As the title suggests, I'd like to hear some collective thoughts and experiences on expected equipment lifetimes.<br>
Obviously very dependent on what it is, what it does, who made it, who uses it, etc., etc. but in a very general sense when is the average piece of equipment (if there is such a thing) on borrowed time? I'm sure we all have some decades old machines and that
replacing them solely for modernization's sake would be considered financial malfeasance. However, under a more manufacturing mindset a strategy for planned obsolescence is not a bad idea.<br>
<br>
To hopefully facilitate some replies/debate/conversation, here's my two cents:<br>
<br>
Metrology Equipment --> 5-10 years<br>
Processing Equipment --> 12-17 years<br>
<br>
Also took a quick age survey of our ~50 pieces of equipment and found the following distribution:<br>
<br>
<img alt="" width="310" height="195" data-outlook-trace="F:1|T:1" src="cid:part1.ZHud0TOf.NGkXVVJ4@rpi.edu"><br>
<br>
If the pie chart graphic isn't visible: 0 tools < 5years, 15 tools between 5 and 10 years, 17 tools between 5 and 10 years, 18 tools < 20 years<br>
<br>
Be well,<br>
Bryant<br>
