Mid-end and backend process technology (WET/Integration/Metal deposition/Lithography engineer)

Job Description

SPS (Smart Power Stage) products are expected to see significant demand growth from 2025 to 2030, with a particular surge in demand for AI servers. These devices, especially embedded VPS such as PT (Power Tower Module) and VPS (Vertical Power Stage), require Mid-end processes such as Cu-RDL, backside metal, and ultra-thinning of Si, which also help differentiate from competitors.Renesas is strengthening in-house manufacturing, and as part of this, we plan to develop technologies for these Mid-end processes, secure production capacity and shorten LT through in-house production. These in-house productions are also strongly requested by customers. Going forward, chiplet technology that maximizes performance while reducing manufacturing costs and shortening development periods will increasingly require Mid-end processes such as RDL and bumps.This time, we are recruiting personnel who understand the structure and characteristics of power devices and can build optimal processes from Mid-end processes such as RDL and OPM to back-side processes and dicing, as we internalize embedded VPS. By acquiring personnel well-versed in Mid-end and backside processes, it becomes possible not only to develop internal processes but also to respond to issues in OSAT.We are seeking process engineers in the following four areas: 【Roles and Responsibilities】1WET process engineerPromotion of WET process development for Mid-end and backend processes of new productsTechnical responses and reporting based on WET process developmentSupport for manufacturing line startup and mass production transitionPromotion of product quality and yield improvement activitiesSupport for technology development of new materials and new manufacturing methods related to WET processSupport for cost reduction activities in traditional WET processes2Integration engineerPromoting process development for Mid-end and backend processing of new productsTechnical responses and reporting based on process developmentSupport for manufacturing line startup and mass production transitionPromotion of product quality and yield improvement activitiesSupport for technology development of new materials and new manufacture developmentSupport for cost reduction activities in conventional processes3Metal deposition engineerPromotion of metal deposition process development for intermediate and backend processes of new productsTechnical responses and reporting based on metal deposition process developmentSupport for manufacturing line startup and mass production transitionPromotion of product quality and yield improvement activitiesSupport for technology development of new materials and new manufacturing methods related to metal deposition processSupport for cost reduction activities in traditional metal deposition processes4Lithography engineerPromotion of lithography process development for Mid-end and backend processing of new productsTechnical responses and reporting based on lithography process developmentSupport for manufacturing line startup and mass production transitionPromotion of product quality and yield improvement activitiesSupport for technology development of new materials and new manufacturing methods related to lithographySupport for cost reduction activities in traditional lithography-related processesQualifications1WET process engineerRequired:Over 2 years of experience in WET process development or mass productionExperience in developing or evaluating WET process-related materialsExperience in developing or evaluating WET process-related equipmentDegree in engineering (mechanical, materials, electronics, chemistry, etc.)Preferred:Basic knowledge of power devicesKnowledge of reliability testing evaluationPractical experience in process improvement and quality controlExperience in complying with quality standards such as ISO/IATF2Integration engineerRequired:Over 2 years of experience in semiconductor integration development after metallizationBasic knowledge of power devicesKnowledge of reliability testing evaluationPractical experience in process improvement and quality controlDegree in engineering (mechanical, materials, electronics, chemistry, etc.)Preferred:Experience in semiconductor package developmentDevelopment experience in wafer process technology startupExperience in complying with quality standards such as ISO/IATF3Metal deposition engineerRequired:Over 2 years of experience in semiconductor metal deposition process development or mass productionExperience in developing or evaluating metal deposition-related materialsExperience in developing or evaluating metal deposition-related equipmentDegree in engineering (mechanical, materials, electronics, chemistry, etc.)Preferred:Basic knowledge of power devicesKnowledge of reliability testing evaluationPractical experience in process improvement and quality controlExperience in complying with quality standards such as ISO/IATF4Lithography engineerRequired:Over 2 years of experience in semiconductor lithography technology development or mass productionExperience in developing or evaluating lithography-related materialsExperience in developing or evaluating lithography-related equipmentDegree in engineering (mechanical, materials, electronics, chemistry, etc.)Preferred:Basic knowledge of power devicesKnowledge of reliability testing evaluationPractical experience in process improvement and quality controlExperience in complying with quality standards such as ISO/IATFAdditional Informationルネサスは、「To Make Our Lives Easier 」(人々の暮らしを楽“ラク”にする)というPurposeの下、組み込み半導体ソリューションを提供します。高品質とシステムレベルノウハウを兼ね備えた組み込み半導体のリーダーとして、自動車、産業、インフラ・IoT分野向けに、ハイパフォーマンスコンピューティング、組み込みプロセッシング、アナログ&コネクティビティ、そしてパワーを含めた幅広い製品ポートフォリオを軸とした、スケーラブルで包括的なソリューションを提供しています。
