Lift-off Processes with Photoresists
Beside wet or dry etching, lift-off is a common technique to pattern metal or dielectrica films in the μm or sub-μm range. The main criteria for the choice of a photoresist best-suited for a certain lift-off process are: The thickness of the coated material The coating technology (evaporation, sputtering, CVD, ...) and the maximum temperature the resist film has to stand during coating The requ...
متن کاملTransport Properties of Epitaxial Lift Off Films
Transport properties of epitaxially lifted-off (ELO) films were characterized using conductivity, Hall and Shubnikov-de Haas measurements. A 10-15% increase in the 2D electron gas concentration was observed in these films as compared with adjacent conventional samples. We believe this result to be caused by a backgating effect produced by a charge build up at the interface of the ELO film and t...
متن کاملWe Had So Much Fun. Now What?
The declining enrollment is a dilemma that many information systems programs are facing. In this study, we design a “Mobile Star” project to promote the information systems major to high school students in Texas. Each “Mobile Star” project consists of a mobile app development workshop and the student’s app showcase. We expect to explore whether the student’s perceived completion, perceived achi...
متن کامل'Had we but world enough, and time'.
This paper will cover a general discussion of changes and improvement in software. I will focus on some special aspects of the evolutionary process, and propose to extend those techniques and approaches.
متن کاملWould that we had the energy.
It was back in the early 1980s. My thoracic surgical colleague asked if I could help him with one of his patients who had developed breathing problems after a lobectomy. The man was on a respirator, the consequence (it turned out) of a post-operative attack of asthma. By the time he had recovered, the pathologist reported the resected lobe to have contained not cancer but pneumoconiotic massive...
متن کاملRepresentational formalisms: why we haven’t had one
Currently, the only discipline that deals with scientific representations— albeit non-structural ones—is mathematics (as distinct from logic). I suggest that it is this discipline, only vastly expanded based on a new, structural, foundation, that will also be dealing with structural representations. Logic (including computability theory) is not concerned with the issues of various representatio...
