Amtech Systems Sees AI Chip Packaging as Its Next Growth Engine

Key Points

• AI packaging is Amtech’s key growth opportunity: Its high-temperature reflow furnaces and patented TrueFlat technology support advanced packages containing GPUs, TPUs and high-bandwidth memory. Production has increased to 10–12 systems per week, while demand is strengthening across outsourced assembly, memory and processor customers.
• The company has improved its financial position: Restructuring reduced its facilities from seven to four, eliminated debt and helped produce $83 million in cash, a 50% gross margin and a 15% EBITDA margin in the latest quarter.
• Amtech plans to expand beyond its current packaging process: Management is evaluating additional advanced-packaging steps and potentially small technology acquisitions, while a 1.4-to-1 thermal book-to-bill ratio and growing forward orders indicate improving backlog visibility.

Amtech Systems NASDAQ: ASYS is positioning its thermal processing equipment business to benefit from growth in artificial intelligence infrastructure, while seeking to expand into additional semiconductor packaging process steps, Executive Chairman Bob Daigle said during a company presentation.

Daigle said Amtech has annualized revenue of about $90 million, with approximately 80% generated by its Thermal Processing Solutions segment and 20% from Semiconductor Fabrication Solutions. The thermal segment primarily supplies furnaces used in electronics applications, while the semiconductor fabrication business includes parts, services and consumables supporting chemical mechanical planarization tools.

The company’s primary AI-related opportunity is in reflow equipment used in advanced chip packaging. Daigle said Amtech’s high-temperature furnaces are used to melt ball grid arrays during the assembly of chip packages, including packages containing GPUs, TPUs and high-bandwidth memory.

TrueFlat Technology and AI Packaging Demand

Daigle highlighted Amtech’s patented TrueFlat technology, which uses vacuum to hold substrates flat as they move through a tunnel furnace. The technology was developed to address bowing and twisting that can occur when plastic substrates are heated during soldering processes.

According to Daigle, the company had previously become a “process of record” for computer CPU-related applications and has seen AI become an inflection point for the business. He said Amtech believes a majority of GPUs and TPUs use its equipment for the relevant package-assembly process.

Amtech manufactures much of this equipment at its Shanghai facility, which primarily handles assembly, testing and shipping. It also uses a contractor in the Malaysia-Singapore region to serve the U.S. market in response to tariffs, Daigle said.

The company increased production from about four systems per week roughly 18 months ago to about 10 to 12 systems per week in the most recent quarter, Daigle said. Despite the increase, he said lead times remained about six weeks, including two weeks for building and two weeks for testing.

Daigle said the company’s customers include outsourced semiconductor assembly and test providers, memory manufacturers and processor companies. He added that Amtech has received favorable customer feedback for scaling production without quality problems or substantial price increases.

Financial Restructuring and New Leadership

Daigle, who moved from chief executive officer to executive chairman in August, said he had spent approximately two and a half years restructuring Amtech after taking the CEO role when the company was carrying bank debt, burning roughly $3 million in cash per quarter and operating at a loss.

The restructuring reduced the company’s operating footprint from seven factories to four facilities. Amtech now has only one of those four facilities still building equipment, a shift Daigle characterized as a “semi-fabless” or, in some cases, fabless model.

Daigle said the company paid off its debt and strengthened its cash position. He cited $83 million in cash and no debt following a capital raise, as well as gross margin of 50% and EBITDA margin of 15% in the most recent quarter.

Guy Shechter succeeded Daigle as CEO in August. Daigle said Shechter has about 30 years of semiconductor industry experience, including more than 20 years at Veeco and most recently experience with YES, a chip-packaging company. Daigle said Shechter’s background with capital equipment, customers and supply chains aligns with Amtech’s next phase of expansion.

Expanding the Addressable Market

While Daigle said industry tailwinds alone could potentially support growth from about $90 million in annual revenue to approximately $150 million over the next several years, the company intends to pursue a broader opportunity in advanced packaging.

Amtech currently participates in one of the multiple operations involved in producing advanced chip packages, according to Daigle. He said the company is evaluating ways to enter additional process steps, where customer equipment spending and potential margins may be higher. Some existing equipment used in those steps consists of lower-throughput batch tools that can be expensive, he said.

The company may consider small acquisitions that provide enabling technologies, particularly capabilities needed for more stringent clean-room environments. However, Daigle said Amtech does not intend to pursue a large acquisition simply to buy its way into another packaging process.

• Potential acquisition targets would likely be smaller, privately held businesses, Daigle said.
• He said Amtech has the balance sheet capacity to pursue opportunities without necessarily undertaking a dilutive transaction.
• Any deal would need a clear path to an attractive return on investment, he added.

Backlog, Packaging Trends and U.S. Manufacturing

Daigle said Amtech’s book-to-bill ratio in the thermal processing segment was about 1.4-to-1 in the latest quarter, compared with 1.2-to-1 in the prior quarter. Historically, the business had limited visibility because customers could receive equipment within about six weeks, he said. More recently, larger customers have been placing orders further ahead to secure supply-chain capacity.

He said the company is now receiving bookings extending one or two quarters into the future and is building backlog that it historically did not have in the segment. Daigle cited planned fab expansion by assembly and test providers as a source of potential demand for dozens or, in some cases, up to 100 pieces of equipment per facility.

Daigle also identified co-packaged optics and panel-level packaging as potential secular tailwinds. He said these applications place greater importance on yield, temperature uniformity and substrate flatness, areas where Amtech’s differentiated equipment can compete.

On semiconductor manufacturing expansion in the U.S., Daigle said wafer-level investment has already occurred, while domestic packaging expansion is beginning but may take longer. He cited labor requirements and the need to rebuild technical skills in U.S. packaging operations as challenges, noting that assembly and packaging have historically shifted to Asia.
