Andrew, I believe your mention of Chip Express' process has been determined to be ablative approach which produces parts unsuitable for production or even long term evaluation. One thing is for sure the process mentioned in use at Cal ASIC is unique, and not offered anywhere else. There are similar methods but they are more costly. Below is an analysis done by Jmar concerning Cal ASIC's competetors

In the area of specialty semiconductors, the Company's Cal ASIC
division faces competition from a small number of gate array producers using
traditional semiconductor manufacturing techniques with the attendant processing
times and costs. Currently customers needing only small volumes of custom
integrated circuits have few choices. They must either use expensive field
programmable gate arrays, or pay high costs to a major producer for limited
production, or develop their application using discrete components. Cal ASIC
provides another alternative through the use of a unique direct write
lithography approach that eliminates photomask generation and allows much faster
prototyping and cost effective small volume production. Additionally, Cal ASIC's
direct write lithography approach will permit multiple designs to be written on
the same wafer, giving customers the ability to do multiple iterations of their
designs at one time. While one competitor does use a laser in their prototype
offerings, it is an ablative approach which the Company believes produces parts
unsuitable for production or even long term evaluation.
