JMAR Technologies bought Semiconductor Advanced Lithography (SAL) in 2001 to pair SAL’s X-ray lithography steppers with JMAR’s laser-plasma X-ray sources and develop a complete lithography system. The deal gave JMAR the missing exposure-tool capability, but later disclosures show that key development and commercial milestones remained unresolved.
Why did JMAR buy SAL?
JMAR had been developing laser-plasma X-ray sources; SAL made X-ray lithography stepper systems. Buying SAL was a vertical-integration move: JMAR sought to combine the source and the equipment that exposes a wafer, so it could offer a more complete system instead of only a source. EDN reported the plan on April 17, 2001, describing SAL as a stepper supplier and the combined effort as an attempt to serve gallium-arsenide (GaAs) semiconductor fabs.
The initial market rationale centered on high-speed communications chips made with GaAs. JMAR also presented X-ray lithography as a possible alternative to extreme ultraviolet (EUV) lithography, saying its system could be “cheaper and available sooner than EUV-based systems,” as reported by EDN. That was JMAR’s strategic claim, not evidence that the system reached customers sooner or at lower cost.
What did JMAR get, and how much did the acquisition cost?
SAL brought X-ray stepper systems and capability related to developing a CPL system. The merger agreement, signed July 24, 2001, provided for SAL to merge into a JMAR subsidiary, JMAR/SAL Lithography, Inc. JMAR’s later filings refer to the combined operation as JMAR/SAL NanoLithography, or J-SAL.

EDN reported the completed purchase on August 10, 2001, at an approximate value of $4.5 million. JMAR’s 2005 Form 10-K gives the acquisition date as August 7, 2001, and records a purchase price of $4,297,414, including transaction costs. It describes the consideration as 603,051 JMAR shares valued at $1.7 million, $1.2 million in cash, and $1.2 million in notes. The figures differ in precision and presentation: EDN gave a rounded transaction value, while the filing supplied the accounting purchase price and its components.
What was the integrated system supposed to do?
The goal was to install JMAR’s laser-plasma X-ray source into a SAL stepper and integrate the equipment into an X-ray lithography system for semiconductor manufacturing. Photonics Spectra reported that nearly $7.8 million in DARPA-sponsored funding, from the U.S. Army Robert Morris Acquisition Center in 2001, supported an engineering prototype. The planned work included analysis of the SAL stepper test stand, a larger-field X-ray collimator, raising source power to at least 45 watts, and initial integration into SAL’s Model 5 stepper.
In the same report, JMAR CEO John S. Martinez said the company expected a separate DARPA contract before the end of 2001 to complete the purchase of a Model 5 stepper, install JMAR’s source, and carry out final installation and checkout. That statement described an expectation at the time; it does not establish that the separate contract was awarded or that the integrated system completed checkout.
Did JMAR’s X-ray lithography strategy succeed?
The available milestones point to development and commercialization challenges, not demonstrated broad commercial success. JMAR later disclosed that the first SAL earn-out depended on meeting a stepper-limited throughput test by June 30, 2002, and that the requirement was not met. In 2004, the company described uncertainty about market acceptance of the CPL system and delays in completing it.

Those disclosures do not by themselves establish that every part of the program ended or that no equipment was ever delivered. They do show why the acquisition should be judged separately from the strategic rationale: combining a source and a stepper created the possibility of an integrated system, but proving throughput, completing the CPL system, qualifying it with customers, and achieving commercial shipments were distinct hurdles. The cited record documents goals and setbacks, not broad commercial adoption or a verified win over EUV.

JMAR’s 2007 accounting disclosure said all of its goodwill arose from the SAL acquisition and was allocated to the Vermont Operations/Research Division. The company linked that unit to source development as well as system design, integration, testing, and assembly. That accounting treatment shows how JMAR organized the combined capabilities; goodwill allocation is not, on its own, evidence of commercial performance.
