Clean rooms? Bah. I've made BJT's with beta>700 in the filthiest lab you can imagine. I'm talking about a lab that my office mate occasionally takes his dog into with him for company. We use a planar process that could be done at home except for the evaporative metallization. FET's need a little bit more careful handling, but the primary demon isn't dust as much as Sodium contamination. As someone has pointed out, alloyed junction transistors ought to be fairly simple to make at home, but you've still got to figure out how to get the contacts on. -- John Berryhill 143 King William, Newark DE 19711
