The following companies seem to be the "players" in the new world of direct write lithography for PCBs and advanced IC packages. The data below is collected from their WEB pages.
ATD Maskless Direct Write Tool. 3000MT:Laser driven at 248 nm. Supports 6 inch wafers. 0.25 um resolution. 1500: 405 nm laser diode, 6" wafers, 1.5 um resolution. Not sure if this uses DMD technology.
Update Dec 2017 - The link to this website seems to have died
Maskless was an early pioneer in direct exposure for PCB. Their system uses 7 heads to increase throughput.
Update - Maskless Technology sold its assets and technology to Chime Ball Technology in Taiwan in early January 2015. The above link no longer goes to the company. Chime Ball seems to sell a machine called the Phoenix 5000 series with the same appearance as the original Maskless Lithography equipment.
They have a very impressive description of their equipment on their WEB page. (HDP-550 data sheet PDF) They claim to have a proprietary data processing system that "can process image files on-the-fly without waiting time to ensure fast and accuracy scanning even for a large exposure area."
They have a machine (DW-3000) designed for direct writing onto finished wafers (primarily for the packaging market where packages are built directly onto wafers ...) It has 3 um resolution, up to 300 mm wafer, can write both the die and the ID (dynamic text) and so on. 64 wafers per hour means less than 1 minute per 300 x 300 area.
Update Dec 2017 - a recent review of their web site shows a new machine - the DW-6000 designed for panel level packages. This supports die-by-die alignment and supports panels up to 620 x 650 mm. They claim to support up to 70 panels per hour at 5 um L/S and on a 500 x 500 mm panel.
Formerly a manufacturer of photo plotters. Now working on a LDI machine called the StarBurst. Not much information at this time.
Update Dec 2017 - they seem to have pretty much disappeared.
Fuji Film makes a machine called the Inprex. It actually is a pair of mask writers - one for the top side of the board and the other for the bottom of the board.
Update Dec 2017 - Fuji contracted out manufacturing of the INPREX exposure equipment to Adtech, Japan in the period around 2008/2009. In 2012 Adtech became a subsidiary of Ushio Inc and in 2014 all exposure equipment business including design, sales and manufacturing was transferred from Fujifilm.
Their new VPG line - small area (200 and 400) uses a high power DPSS laser and supports substrates of up to 8" and 16" respectively. the VPG 1100 supports large panels ranging in size from 800 x 800 mm up to 1400 x 1400 mm.
Update Dec 2017 - the DE-8WH, a new machine for FOWLP was announced in July 2017. It can expose 2 um L/S with plus/minus 1 um overlay. The machine can process 620 x 620 um panels or 300 mm wafers.
Direct Write machine developed by Index Technologies
The Manz SpeedLight 2D uses 288 GaN laser diodes at 405 nm coupled through fibers. Achievable line widths and gaps depend on the resist but range from 25um to 50 um. The input data is rasterized as 12,700 DPI. Maximum panel size is 660 mm x 650 mm.
Manz got into the LDI business by acquiring KLEO Halbleitertechnik GMBH in mid 2015.Manz claims:
Realtime scaling/Distortion compensation
LDI 5s Series: UV direct writer (gray-scale approach) distortion correction. Uses 355 nm diode source and supports panels up to 510 x 515 mm. Twin stages - alignment and focus mapping on one while writing on the other.
Update Dec 2017 - Mycronic stopped development of their LDI efforts sometime in 2014 per their annual report.
Paragon Ultra Family for PCBs and packages ... I believe Orbotech may be the largest supplier of direct imaging for PCB market.
ORC started by supplying lamps to the exposure equipment industry and somehow they now have an exposure machine. Unfortunately their site is in Japanese so I cannot tell much from it about their direct exposure product.
Recently notified about PMT's PLS-3000 machine. Supports 300 mm wafers using a 1920x1080 DMD and a LED illumination source running at 405 nm.
USHIO announced a new UID-8001P direct exposure machine for flip chip manfacturing.
This Norweigan company sells a lithography system but main focus seems to be the light engines (DMD assembly, driver electronics) Texas Instruments design partner.
