Job's mission

As a Senior Engineer II, Process Engineering (tALD) at ASM, you will lead advanced process development focused on thermal Atomic Layer Deposition (tALD) technologies to enable next-generation semiconductor devices. In this role, you will be responsible for developing, optimizing, and transferring high-performance thin film processes, while collaborating closely with customers and cross-functional teams to deliver differentiated solutions aligned with advanced technology nodes.

What you will be working on

Lead development and optimization of thermal ALD (tALD) processes for metal and dielectric thin films targeting advanced semiconductor applications

Design and execute complex experiments using Design of Experiments (DOE) and advanced statistical methodologies to optimize process performance and window

Develop and qualify new precursor chemistries, reaction mechanisms, and deposition conditions for tALD processes

Analyze and interpret material and film properties using advanced characterization techniques (e.g., SEM, TEM, XPS, SIMS, ellipsometry)

Drive process integration of tALD films into FEOL/BEOL device architectures and customer flows

Identify and resolve process and equipment issues through hands-on troubleshooting and root cause analysis

Collaborate with hardware engineering teams to define tool requirements and improve reactor performance specific to tALD applications

Work closely with customers, account teams, and global R&D to align process development with technology roadmaps and application requirements

Support technology transfer by delivering customer demonstrations, technical documentation, and training to field teams

Contribute to technical publications and intellectual property (IP) generation in tALD process and materials development

Stay updated on state-of-the-art ALD/tALD technologies and proactively introduce innovative ideas into development programs

What we are looking for

PhD in Chemical Engineering, Materials Science, Physics, Electrical Engineering, or a related discipline, or MS with 5–8+ years of relevant semiconductor industry experience, with strong hands-on experience in Atomic Layer Deposition (ALD) and a clear focus on tALD process development

Deep understanding of tALD surface reactions, precursor chemistry, and film growth mechanisms, along with proven experience in thin film deposition process development and optimization

Strong knowledge of metal and dielectric film deposition and integration, including hands-on experience with DOE, data analysis, and process characterization techniques

Ability to independently lead complex process development activities from concept through transfer, with experience working in semiconductor cleanroom environments

Strong communication skills in English (Korean preferred), with the ability to clearly articulate complex technical concepts and collaborate effectively with cross-functional teams

What sets you apart

Experience integrating tALD-based films into advanced logic, memory, or 3D device architectures

Hands-on experience with selective ALD / Area Selective Deposition (ASD)

Experience in precursor evaluation and development for thermal ALD processes

Familiarity with scaling challenges for high aspect ratio (HAR) structures

Prior experience supporting customer engagement, demonstrations, and process transfer

Apply today to be part of what’s next.

We make the tech that enables the chips in devices which improve lives around the world. We do this with an eye to the future, pushing the boundaries of what’s possible through cutting-edge innovation, and driving the next wave of technological breakthroughs that shape how we live, work, and connect.
