As the industry is getting their hands around processes critical to cost-effective and reliable TSV manufacturing a key enabler is process control through inspection and metrology. In working with the industry, Rudolph has developed a suite of solutions that incorporate inspection, metrology and software enabling rapid yield ramp. The solution set apply all the way from via etch to CMP, RLD, micro-bumping and all the way to Chip on Wafer mount and post-saw. Within the TSV process a challenging inspection is that of detecting defects after CMP and nail reveal. The bonded wafers are warped, there are no alignment fiducials and the resolution requirement is high. Rudolph has developed a specific solution designed to address the nail reveal defectivity issue.

As the industry is investigating more cost-effective and reliable Cu Pillar Bumping as well as TSV, a key enabler is process control through inspection and metrology. In working with the industry, Rudolph has developed a suite of solutions that incorporate inspection, metrology and software enabling rapid yield ramp. The solution set applies to via etch, CMP, RDL, micro-bumping and all the way to Chip on Wafer mount and post-saw. As an example, within the TSV process a challenging inspection is that of detecting defects after CMP and nail reveal. The bonded wafers are warped, there are no alignment fiducials and the resolution requirement is high. Rudolph has developed a specific solution designed to address the nail reveal defectivity issue as well as metrology sensors to measure the nail height. Micro Pillar bumps and C4 bumps are the main bump geometries used in 3D packages as their small pitch and size allow the required number of I/Os. Rudolph will discuss an inspection system that incorporates multiple metrology sensors to provide complete 2D and 3D measurement and inspection solutions.

<p class="1">Meeting teacher expectations for a professional development programme (PDP) is expected to strengthen sustainable applied competence as programme outcome since teachers will be more motivated to apply the programme content in practice. A revised distance learning (DL) programme was augmented by a practical component comprising a work-integrated portfolio and audio-visual material, aimed to support the applied competence of practising teachers in the South African context. An evaluation of the way the programme measured up to teacher expectations was deemed critical for future DL programme design. A qualitative study based on an interpretivist philosophical approach collected data of teacher expectations <em>for </em>and <em>of</em> the practical component through multiple methods. Their contributions were linked with four main themes related to applied competence as identified in the literature. Participant expectations and experiences with regards to each theme were compared by means of electronic coding through ATLASti™. The findings show a strong correlation between expectations <em>for</em> and experiences <em>of </em>the way the practical component supports the elements of applied competence. Since DL is viewed as a viable and cost effective way to improve teacher competence in developing countries, these findings serve as impetus for further investigation and refining ways to support applied competence in a distance learning professional development programme (DL PDP).</p>

AbstractTraditionally, the first step in the development of drugs is the definition of the target, by choice of a biological structure involved in a disease or by recognition of a molecule with some degree of a biological activity that presents itself as druggable and endowed with therapeutic potential. The complexity of the pathophysiological mechanisms of disease and of the structures of the molecules involved creates several challenges in this drug discovery process. These difficulties also come from independent operation of the different parts involved in drug development, with little interaction between clinical practitioners, academic institutions and large pharmaceutical companies. Research in this area is purpose specific, performed by specialized researchers in each field, without major inputs from clinical practitioners on the relevance of such strategy for future therapies. Translational research can shift the way these relationships operate towards a process in which new therapies can be generated by linking experimental discoveries directly to unmet clinical needs. Computational chemistry methods provide valuable insights on experimental findings and pharmacological and pathophysiological mechanisms, allow the virtual construction of new possibilities for the synthesis of new molecular entities, and pave the way for informed cost-effective decisions on expensive research projects. This text focus on the current computational methods used in drug design, how they can be used in a translational research model that starts from clinical practice and research-based theorization by medical practitioners and moves to applied research in a computational chemistry setting, aiming the development of new drugs for clinical use.
