SEM photomicrograph

Sodium starch glycolates are generally spherical, a characteristic which accounts for their good flowability [4]. Figure 1 shows the scanning electron photomicrographs (SEMs) of some the commercial sodium starch glycolates.

Optimization of the deep-UV exposure and aqueous TMAH development steps for all three parent phenolic resins formulate with the diazonaphthoquinone dissolution inhibitor resulted in the resolution of positive tone 0.75 pm L/S patterns at a dose of 156, 195 and 118 mJ/cm2 for the o-cresol, 2-methyl resorcinol and PHS materials, respectively (Table V). The copolymers prepared with a 4400 g/mole PDMSX resulted in TMAH soluble films at >11 wt % silicon however, the feature quality was extremely poor in each case.

Various noncellulosic thln-film-composlte membranes were examined by scanning electron microscopy (SEM). Figure 3 illustrates the type of surface structure and cross-sections that exist in these membranes. Figure 3a shows the surface microporosity of polysulfone support films. Micropores in the film were measured by both SEM and TEM typically pore radii averaged 330 A. Figure 3b is a photomicrograph of a cross-section of a NS-lOO membrane.
