See Brundall, this is the kind of discussion I would like to have on this forum!
And I hope the forum members more familiar with these structures and semiconductor technology would chime in!
Your findings are very interesting!
Sure, out of the 59 patents listed for Opel Inc I counted 24 that were thyristor related (40%) and 6 (10%) were related to solar products. This in no way means the thyristor patents are useless and the remaining 50% of our patents relate to other goodies. Excellent news.
So we have 24 patents (40% of the POET patent portfolio) which are related to thyristors.
- I would like to know how many of them need this forth terminal which is making problems at the moment?
And more important:
As I very well know: you need to proof your findings in a patent by experimentals and prototypes. So I assume that GT and his team at UCONN succeded in producing these four terminal thyristors. So where do these problems now (with the optical engine) come from?
- Did they produce "bigger" structures at UCONN which were more easy to produce?
- Or did they use other technology (MBE?) which at that time worked out nicely, but can not (yet) be used in mass production?
- For mass production I guess POET is now using ready made epi wafers etching the thyristor out of these wafers. Did UCONN produce these structures with a totally different method (e.g. building each layor separately)?
Please believe me that I am not totally pro POET. I would also like to find the critical issues in technology as well as management, but I'd like to receive compehensive facts, not feelings, emotions and repetition of things I already know for long long time!
P.S.: Thanks to all the bordmembers who are delivering more signal then noise! Thanks Brundall!
