This paper summarizes the application of ultramicrotomy as a specimen preparation technique for some of the Materials Science applications encountered over the past two years. Specimens 20 nm thick by hundreds of μm lateral dimension are readily prepared for electron beam analysis. Materials examined include metals, plastics, ceramics, superconductors, glassy carbons and semiconductors. We have obtain chemical and structural information from these materials using HRTEM, CBED, EDX and EELS analysis. This technique has enabled cross-sectional analysis of surfaces and interfaces of engineering materials and solid state electronic devices, as well as interdiffusion studies across adjacent layers.Samples are embedded in flat embedding moulds with Epon 812 epoxy resin / Methyl Nadic Anhydride mixture, using DY064 accelerator to promote the reaction. The embedded material is vacuum processed to remove trapped air bubbles, thereby improving the strength and sectioning qualities of the cured block. The resin mixture is cured at 60 °C for a period of 80 hr and left to equilibrate at room temperature.

ABSTRAKPenelitian ini berjudul “The Media Conspiracy Behind the Death of Diana, Princessof Wales: A Study of Critical Discourse Analysis”. Penelitian ini bertujuan untuk menjelaskanbagaimana kematian Putri Diana direpresentasikan oleh The Daily Mail dalam artikelartikelpemberitaannya melalui dimensi tekstual dan juga memaparkan cara pandang TheDaily Mail sebagai pelaku media konspirasi pada praktik kerjanya terkait berita kematianPutri Diana dalam dimensi sosiokultural. Objek penelitian ini adalah The Daily Mail, salahsatu tabloid harian terbesar di Inggris. Metode yang digunakan dalam penelitian ini adalahmetode kualitatif, analisis deskriptif. Penulis menggunakan teori analisis wacana kritisFairclough (1995), disertai dengan beberapa teori pendukung lainnya, seperti teori klausasebagai representasi Halliday (2004), teori konspirasi Feaster (2008), Birchall (2006),Barkun (2003), Hodapp dan von Kannun (2008). Hasil dari penelitian ini menunjukkanbahwa representasi kematian Putri Diana dalam dimensi tekstual didapat melalui prosesmaterial, proses mental, proses relasional, proses verbal, dan proses eksistensial yangterdapat dalam artikel-artikel The Daily Mail. Sementara itu, cara pandang The Daily Mailsebagai pelaku media konspirasi atas berita kematian Putri Diana didapat melalui prosestataran sosial, tataran institusional, tataran sosial pada dimensi praktik sosiokultural.Kata Kunci: Transitivitas, Analisis Wacana Kritis, Media konspirasi.ABSTRACTThis thesis is entitled “The Media Conspiracy Behind the Death of Diana, Princessof Wales: A Study of Critical Discourse Analysis”. This thesis is aimed to describe therepresentation of Princess Diana’s death and The Daily Mail’s perspective as a mediaconspiracy actor through textual and sociocultural dimension. The object of this thesis isThe Daily Mail, one of the widest national daily newspapers in England. The method that isused in this thesis is a qualitative method, a descriptive analytic method. The writer uses thecritical discourse analysis theory of Fairclough (1995) and some other supported theories,such as clause as representation theory by Halliday (2004), the conspiracy theory by Feaster(2008), Birchall (2006), Barkun (2003), Hodapp and von Kannun (2008). The result of thisresearch shows that the representation in textual dimension that appear on Princess Diana’sdeath is derived from material process, mental process, relational process, verbal process, andexistential process. While The Daily Mail’s perspective on Princess Diana’s death is derivedfrom situational level, institutional level and social level of sociocultural practice dimension.Keywords: Transitivity, Critical Discourse Analysis, Media Conspiracy.

Abstract The characteristics of an organic low-k dielectric during investigation by focused ion beam (FIB) are discussed for the different FIB application modes: cross-section imaging, specimen preparation for transmission electron microscopy, and via milling for device modification. It is shown that the material is more stable under the ion beam than under the electron beam in the scanning electron microscope (SEM) or in the transmission electron microscope (TEM). The milling of the material by H2O vapor assistance is strongly enhanced. Also by applying XeF2 etching an enhanced milling rate can be obtained so that both the polymer layer and the intermediate oxides can be etched in a single step.
