Tim, thanks for the posting of the information on TFT production using lasers and JMAR's involvement. I was not aware that JMAR was this far into high definition TV and LCD screens. As a lot of us know, buying a laptop with a TFT screen is a very expensive proposition. I would like to know if using JMAR's Bright Light technology will reduce substantially the cost of these screens. What about quality? This is yet another use of JMAR's proprietary technology. I would like to know what their timetable on this is. Is this one of those projects that JMAR has been keeping to itself? You and everyone on this board have a good and profitable new year. Lets hope that 1998 makes JMAR a household name (at least with brokers and CNBC). --Bilberry

Tim, I read more info from the web site you provided and the Hitachi of Japan involvement in the flat panel LCD TFT displays. I have to wonder if JMAR is doing work with Hitachi and whether there is a joint venture coming out of this. I will try to find out more info on this. It seems that JMAR has a lot of things going on that they are keeping under wraps until they are ready to make them public. That is both appealing and frustrating to investors. Appealing because we are sitting on a diamond mine waiting to be tapped. Anyone on the board, please see if you can find more info on this LCD flat panel display technology and what is JMAR's involvement with Hitachi? --Bilberry Source: spie.org

Tim, I found more info on the Hitachi connection. Took me several hours of searching on the web. This is really an exciting area. Here is what I found: Paper #: 2992-16 spie.org Excimer ablation lithography (EAL) for TFT-LCD, pp.98-107 Author(s): Kenkichi Suzuki, Hitachi, Ltd., Chiba, Japan; Masaaki Matsuda, Hitachi, Ltd., Chiba, Japan; Toshio Ogino, Hitachi, Ltd., Chiba, Japan; Nobuaki Hayashi, Hitachi, Ltd., Tokyo, Japan; Takao Terabayashi, Hitachi, Ltd., Yokohama, Japan; Kyouko Amemiya, Hitachi, Ltd., Yokohama, Japan. Abstract: The excimer ablation lithography (EAL) is a process of direct patterning and removal of a resist polymer film by photo-decomposition ablation. Comparing to the conventional photolithography, EAL does not need the development process and realizes a non-vacuum dry removal of resist. The main equipment for the new processes is a kind of aligner- exposure for the resist patterning and the removal, which reduce the cost of the clean room and the equipments considerably. This is very attractive for TFT-LCD manufacturing, as it is required to reduce the cost severely. The large area patterning and high throughput are essential for TFT-LCD applications. To prove the feasibility, we fabricated an experimental equipment for ablation patterning. It is equipped with the high precision 300 $MUL 300 mm X-Y stages and a N.A. 0.1 image lens which enable to explore the problems inherent to TFT panel of a real size. In addition, two substantial technologies were developed. One is a dielectric multilayer mask on 8 inch quartz substrate with precision enough for TFT patterns. The other is high ablation rate resist polymer. With these technologies, A4 size TFT laser was fabricated by step and scan method. The results show that EAL is in a good prospect for a new TFT manufacturing technology. !4 Here are a couple of papers published by the head of JMAR Technology, Harry Shields, the same person doing the paper on flat panel LCD with Hitachi: High-average-power picosecond-pulse excimer laser system for x-ray generation Powers, Michael F.; Shields, Harry A(JMAR Technology Co.)
