This blog entry IS about Forza and I was responding to the first 3 comments. I don't have any current business relationship with any of the parties I mentioned.<br /><br />ISW - I was trying to make a general comment about why people use smaller foundries like Tower-Jazz, in response to the 2nd comment. "Baseline process" means baseline CIS process, which then gets tweaked. It is a very good thing that Tower-Jazz does these tweaks as does other smaller-run foundries. And, it is a fundamental axiom to manufacturing engineering that yield and production-run volume go hand-in-hand. It has nothing to do with any specific foundry. I do agree with your last two paragraphs on Tower.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-70920869529343404042010-06-24T16:09:20.372+03:002010-06-24T16:09:20.372+03:00@ "Please screen out such kind of comments on...@ "<i>Please screen out such kind of comments on this blog, it's a self promotion of small circle and misleading to general forumers ...</i>"<br /><br />Actually, I agree with Eric that Forza has a great team. There are other great teams on this planet, which, I think, quite competitive with Forza, but this is another matter.<br /><br />However, I disagree with Eric on his comments about the yield problems at Tower-Jazz. Tower makes full-frame DSLR and X-Ray sensors, some occupying a big part of the wafer. These kind of products are impossible to produce if defect density is not low enough. Now, if we compare yields of mobile VGA sensor with FF DSLR one, they are not directly comparable.<br /><br />Also, my sources tell that TowerJazz makes quite deep CMOS process modifications to improve image sensor quality. It's not just "tweaks" to the standard logic process flow.<br /><br />Also, in many cases Tower provides ready, silicon-proven pixel designs for its customers, and it accumulated a big pixel portfolio over many years. This greatly simplifies image sensor development for the smaller companies.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-86073606013279690092010-06-24T09:37:33.959+03:002010-06-24T09:37:33.959+03:00there should be a very strong electric field someo...there should be a very strong electric field someone's head because his opinion on other design teams is always so polarized !<br /><br />Please screen out such kind of comments on this blog, it's a self promotion of small circle and misleading to general forumers ...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-87586538015397647392010-06-24T00:39:06.132+03:002010-06-24T00:39:06.132+03:00Multiple exposure based HDR solution needs to read...Multiple exposure based HDR solution needs to read out several differently exposed images to form one output image.

Then I got few requests to add more known companies and added them too, one by one, by request. Still, many well known companies are not there, like Panasonic or Sharp. And some companies are not in business anymore, like 3DV or CmoX, but their web sites are still on-line, and I just keep them as hard to find links. Yet some other companies are not exactly sensor ones, like Cap-XX or Apical.<br /><br />There is a different, more complete list of active "core image sensor" companies here:<br /><br />http://image-sensors-world.blogspot.com/2005/11/image-sensor-companies-list.html<br /><br />What kind of categories should be in the list?Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-45361269094225205142010-06-23T19:32:00.269+03:002010-06-23T19:32:00.269+03:00Indeed, there are other excellent teams, some just...Indeed, there are other excellent teams, some just down the street here in Pasadena, others coming out of FillFactory, and a few others. Forza's team is pretty large for a custom design company - I am guessing 50 people, mostly in design. So, depth and breadth-wise, for me, today, it is Forza.<br /><br />Knowing Alex Krymski and LinPing Ang well, they are also very talented and another team I usually recommend when asked. I don't know CMOSIS and Caeleste that well but they both have some outstanding people and for European inquiries, I usually send people in their direction as well. Sorry if I am missing others out there.

To me, it's hard to rank the sensor design groups given different challenges and obstacles they are struggling with - then the net result is hardly comparable.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-86471432625235296912010-06-23T17:21:00.478+03:002010-06-23T17:21:00.478+03:00"Pixm sensor has used already this method&quo..."Pixm sensor has used already this method".. Really? What method is that? I expect the Forza approach is completely different from the Pixim ADC-in-every-pixel approach.<br /><br />Of course tone mapping as a concept is hardly new, but there are many many ways to do this algorithmically incl. hardware and software.<br /><br />Frankly, Forza's design team is probably more advanced than any other on the planet, including Sony and Aptina. However, as a small foundry partner, their influence on processes for advanced pixels is small, compared say to another fabless company like Omnivision.<br /><br />Smaller foundries like Tower-Jazz have business models that are more flexible in order to capture business from smaller production runs. It is a good thing. Unfortunately, in small production runs, it is hard to get a grip on yield improvement for image sensors since they use a standard baseline process with tweaks added for particular sensors. Somehow the tweaks always seem to lead to lower yield. Also, leading edge designs tend to push the envelope for a particular process, also impacting yield.<br /><br />Personally, I am always impressed by the Forza team and have worked with many of the lead guys (gals) either at JPL, Photobit or as a customer at Siimpel. I wish they were part of my team at Samsung!Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-89867910783269615572010-06-23T11:31:00.303+03:002010-06-23T11:31:00.303+03:00if it works, why does it have to be new?if it works, why does it have to be new?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-57461505415207595122010-06-22T22:26:22.750+03:002010-06-22T22:26:22.750+03:00All the small CIS companies work with Tower now :)...All the small CIS companies work with Tower now :)<br />What are the reasons for this ?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-17351655042126836702010-06-22T22:14:58.331+03:002010-06-22T22:14:58.331+03:00Pixim sensor has used already this method.
