Role of electron and ion irradiation in a reliable lift-off process with electron beam evaporation and a bilayer PMMA resist system

نویسندگان

چکیده

This paper addresses issues related to cracking and blisters in deposited films encountered a lift-off process with electron beam evaporation bilayer PMMA resist system. The impact of charged particles, i.e. electrons ions, is investigated using an chamber equipped ring-magnets plate electrode placed front the sample. By replacing hollow cylinder, modified setup utilizing passive components allows complete elimination shrinkage blistering yielding near perfect deposition results for large variety different materials.

Electron beam lithography of HSQ/PMMA bilayer resists for negative tone lift-off process

A HSQ/PMMA bilayer resist system, in which HSQ as negative tone electron beam resist top layer and PMMA as bottom layer, has been investigated for negative tone lift-off process. Patterns are first defined on the HSQ resist using electron beam lithography, and then transferred into the bottom PMMA layer using oxygen reactive ion etching. Electron beam exposure of HSQ on top of PMMA layer has be...

A Quantitative Comparison between Helium Ion and Electron Beam Lithography on PMMA Resist

Helium ion beam lithography (HIBL), an emerging technique that uses a sub-nanometre focused beam of helium ions to expose resist, has introduced an alternative to electron beam lithography (EBL) to extend beyond existing minimum feature sizes. HIBL has several advantages over EBL, including a higher patterning resolution due to a smaller spot size [1] and a reduced proximity effect due to low i...

Treatment of Synthetic Textile Wastewater by Combination of Coagulation/Flocculation Process and Electron Beam Irradiation

Introduction: Textile wastewaters from dyeing and finishing processes are heavily polluted with dyes, textile auxiliaries and chemicals and have a broad range of pH, high COD concentration and suspended particles. In this study, the efficiency of color and turbidity removal from synthetic textile wastewater samples were investigated by combined process of coagulation/ flocculation and electron ...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

a contrastive analysis of concord and head parameter in english and azerbaijani

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
