Engineering Director, MicroE, IME

Role & Responsibilities:

1. Diagnosing appropriate levels of metal/metal-alloy contaminations by oxygen and other contaminants; determining the root cause of contaminants, and establishing protocols for characterizations.
2. Providing hands-on support for onsite metal PVD, including creating, running, and characterizing recipes to achieve the lowest resistances.
3. Collaborating closely with equipment vendors and device engineers to optimize the metal-stack for device performances and robustness/reliability, from low to high temperatures.
4. Leading data analysis related to implant-induced defects and cleaning issues on metal contacts with solutions development.
5. Examining the work-functions of metal/metal-alloys suitable for Ohmic contact on SiC.
6. 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.
7. Designing cleaning processes to obtain ideal Schottky diode using various metal/metal-alloys on SiC for high-performance applications.
8. Working closely with cross-departmental and integration teams and in 3-5 years developing a WBG backend process integration team of at least 4 persons.

Requirements:

1. PhD Degree in Material Science, Physics, Electrical Engineering or related field.
2. >8 years related industrial experience including backend process module integration.
3. Extensive hands-on experience in PVD (Physical Vapor Deposition) processing for metal depositions and interface tuning.
4. Strong understanding of metal-semiconductor contact physics.
5. Expertise in work-function tunings of metal and metal-alloy.
6. Proficiency in modulating electron affinity through implantation or surface treatments of semiconductors.
7. Familiarity with wide band-gap semiconductor materials and their interaction with metal/metal-alloys at various temperatures.
8. Thorough fundamentals in Ohmic contact and Schottky diode physics, as well as the impact of defects and contaminations on electrical properties.
9. Skilled at mentoring and transferring knowledge to junior staff members.
10. Excellent communication skills to effectively address customers' needs, concerns, and solution requirements.
