SEMICON Southeast Asia (SEMICON SEA) is the regional anchor event for a semiconductor supply chain that has, in the last five years, moved from being a downstream assembly hub to a co-leader in advanced packaging and heterogeneous integration (HI). SEMICON SEA 2025 — held in early June, three days long, with Advanced Semiconductor Engineering, Inc. (ASE) participating across keynotes, panels, and a dedicated workforce-development booth — is best read in that context. The event was less about a single product launch and more about the regional capability that has built up around it.
The three-day program produced four distinct ASE moments worth pulling apart: two keynotes, a stage-led packaging discussion, a workforce-development presence, and a closing-day company glimpse. Each addresses a different audience the region needs ASE to talk to.
Keynotes: Tien Wu and Ingu Yin Chang
The keynote slots at SEMICON SEA carry weight because they are how the regional industry sets framing for the year ahead. ASE used both of its slots for that purpose. Dr. Tien Wu delivered one keynote; ASE's Ingu Yin Chang delivered the other.
The substance of those talks was not a single product, but a framing question: as Southeast Asia's role in the global semiconductor supply chain grows, what does the next layer of value capture look like — and how does packaging and heterogeneous integration sit at the center of that?
That framing matters because, until recently, regional industry conversation has been organized around capacity. The SEMICON SEA 2025 keynotes shifted the conversation toward capability: which technology pillars, which talent base, which collaboration models. For an outsourced semiconductor assembly and test (OSAT) leader, leading that shift is consequential — it lines up the regional supply chain with the direction ASE's VIPack™ platform has already been moving.
The Advanced Packaging & Heterogeneous Integration Summit
On the show floor, the Advanced Packaging & Heterogeneous Integration Summit was the stage where the keynote framing turned operational. Ingu Yin Chang led the discussion, articulating AI trends and the critical technology challenges that the industry's roadmap now has to absorb.
Two threads were specifically called out: how the industry should scale, transition, and optimize packaging solutions, and how to do that while improving performance, cost, and efficiency together rather than trading one off against another. The trade-off framing matters because, in earlier generations of advanced packaging, the practical conversation tended to be "pick two" — performance and cost, performance and efficiency, scale and customization. SEMICON SEA 2025's packaging summit took the position that the next generation of the platform should hit all three.
For attendees designing into VIPack™ — particularly the bridge-class pillars (FOCoS, FOCoS-Bridge, FOCoS-Bridge with TSV) that AI accelerator and high bandwidth memory (HBM) integrations now lean on — that framing is more than rhetoric. It is the platform-design principle that lets a single architecture serve workloads from cost-sensitive consumer SoCs to hyperscale AI training silicon.
Workforce Development as a First-Class Topic
Less covered, but arguably equally important to ASE's regional posture, was the workforce-development booth. The booth ran throughout the event, hosting conversations on talent pipelines for advanced packaging and back-end manufacturing — a category of work that, for years, was treated by university curricula as adjacent to "real" semiconductor engineering and is now central to it.
Three forces converged to make that booth necessary:
- Advanced packaging is increasingly silicon-engineering work, not assembly engineering, as RDL pitch shrinks toward 2μm/2μm and below, TSV-grade vertical interconnect enters mainstream packages, and chip package interaction (CPI) becomes a co-design problem rather than a downstream constraint.
- Heterogeneous integration requires multi-domain expertise — substrate design, electrical signal integrity, thermal management, mechanical co-design, AI/ML-driven process optimization — that no single department traditionally trained for.
- The region needs a talent base proportional to its rising share of advanced-packaging capacity, which means engaging universities, polytechnics, and apprenticeship programs ahead of the demand curve rather than behind it.
A workforce-development booth at a SEMICON SEA event is, in effect, ASE saying that the talent layer is on the same roadmap as the technology layer — and inviting the regional ecosystem to plan around that.
Closing Day: A Look Inside ASE
The diary entry closes on Alicia Lee wrapping up Day 3 with a glimpse into ASE — highlighting values, global presence, and the people behind the company's innovations. Closing-day company introductions can feel ceremonial, but in this case the timing is deliberate.
The first two days at SEMICON SEA 2025 were about technology and industry direction. Day 3 closed by reminding the regional audience that ASE is operationally the world's largest OSAT, with manufacturing footprint across Taiwan, Malaysia, Korea, Japan, China, and Singapore (see Milestones), and that the company is making long-term commitments — not just appearing at the event for one cycle. For customers and supply-chain partners in Southeast Asia weighing a multi-year advanced-packaging design partnership, that signal is the one they came to verify.
The SEMICON SEA Throughline
Pulling the four moments together, SEMICON SEA 2025 produced a single coherent message for the regional industry:
- Advanced packaging and heterogeneous integration are where the next layer of regional value capture sits.
- ASE's VIPack™ platform is built to deliver performance, cost, and efficiency together rather than as trade-offs.
- The talent base required to operate that platform at regional scale is being treated by ASE as an explicit roadmap item, not an externality.
- The company's long-running global footprint and forty-year operating history (see Awards) are the basis customers should weigh that platform commitment against.
For attendees who came looking for a product launch, SEMICON SEA 2025 was not that event. For attendees thinking about how to design into Southeast Asia's role in the AI-era semiconductor supply chain over the next three to five years, it was exactly the right event to attend.

Frequently Asked Questions
Q: What was the focus of ASE's keynotes at SEMICON SEA 2025? A: ASE delivered two keynotes at SEMICON SEA 2025 — one by Dr. Tien Wu and one by Ingu Yin Chang. The substance was less about a single product and more about a framing question: as Southeast Asia's role in the global semiconductor supply chain grows, what does the next layer of regional value capture look like, and how do advanced packaging and heterogeneous integration sit at the center of that? Both talks shifted the regional industry conversation from capacity to capability.
Q: Who led ASE's discussion at the Advanced Packaging & Heterogeneous Integration Summit? A: ASE's Ingu Yin Chang led the stage discussion at the Advanced Packaging & Heterogeneous Integration Summit. He articulated AI trends and critical technology challenges, and discussed how the industry should scale, transition, and optimize packaging solutions while improving performance, cost, and efficiency together rather than trading them off against one another.
Q: Why did ASE host a workforce-development booth at SEMICON SEA 2025? A: Advanced packaging is increasingly silicon-engineering work — RDL pitch shrinking toward 2μm/2μm and below, TSV-grade vertical interconnect entering mainstream packages, and chip package interaction (CPI) becoming a co-design problem. Heterogeneous integration requires multi-domain expertise (substrate, signal integrity, thermal, mechanical, AI/ML process optimization), and the Southeast Asian region needs a talent base proportional to its rising share of advanced-packaging capacity. The workforce-development booth was ASE's signal that the talent layer is on the same roadmap as the technology layer.
Q: What is ASE's regional footprint in Southeast Asia? A: ASE's regional footprint includes assembly and test facilities in Malaysia (established in Penang in 1991) and Singapore (with capacity strengthened by the 2010 acquisition of EEMS Test Singapore). Combined with sites in Taiwan, Korea, Japan, and China, ASE operates as the world's largest outsourced semiconductor assembly and test (OSAT) provider, giving regional customers access to capacity within and adjacent to Southeast Asia.
Q: What is the broader takeaway from SEMICON SEA 2025 for the regional semiconductor industry? A: The event's coherent message was that the next layer of regional value capture is in advanced packaging and heterogeneous integration; that ASE's VIPack™ platform is built to deliver performance, cost, and efficiency together rather than as trade-offs; that the talent base required to operate that platform at regional scale is being treated as an explicit roadmap item; and that ASE's forty-year operating history and global footprint are the basis on which customers should weigh that platform commitment.
