Role & Responsibilities:
Requirements:
- Responsibilities include diagnosing appropriate levels of metal/metal-alloy contaminations by oxygen and other contaminants; determining the root cause of contaminants, and establishing protocols for characterizations.
- Hands-on providing support for onsite metal PVD, including creating, running, and characterizing recipes to achieve the lowest resistances.
- Collaborates closely with equipment vendors and device engineers to optimize the metal-stack for device performances and robustness/reliability, from low to high temperatures.
- Lead data analysis related to implant-induced defects and cleaning issues on metal contacts with solutions development.
- Examines the work-functions of metal/metal-alloys suitable for Ohmic contact on SiC.
- Responsible for designing experiments for Ohmic contact on various SiC substrates with different doping types, determining their impact, and resolving issues to achieve the lowest specific contact resistances.
- Designing cleaning processes to obtain ideal Schottky diode using various metal/metal-alloys on SiC for high-performance applications.
- Work closely with cross-departmental and integration teams and in 3-5 years' time develop a WBG backend process integration team of at least 4 persons.
Requirements:
- PhD Degree in Material Science, Physics, Electrical Engineering or related field.
- >8 years related industrial experience inclusing backend process module integration.
- Extensive hands-on experience in PVD (Physical Vapor Deposition) processing for metal depositions and interface tuning.
- Strong understanding of metal-semiconductor contact physics.
- Expertise in work-function tunings of metal and metal-alloy.
- Proficiency in modulating electron affinity through implantation or surface treatments of semiconductors.
- Familiarity with wide band-gap semiconductor materials and their interaction with metal/metal-alloys at various temperatures.
- Thorough fundamentals in Ohmic contact and Schottky diode physics, as well as the impact of defects and contaminations on electrical properties.
- Skilled at mentoring and transferring knowledge to junior staff members.
- Excellent communication skills to effectively address customers' needs, concerns, and solution requirements.
