  • Patent number: 11404267
    Abstract: Systems, apparatuses, and methods related to semiconductor structure formation are described. An example apparatus includes a structural material for a semiconductor device. The structural material includes an orthosilicate derived oligomer having a number of oxygen (O) atoms each chemically bonded to one of a corresponding number of silicon (Si) atoms and a chemical bond formed between an element from group 13 of a periodic table of elements (e.g., B, Al, Ga, In, and Tl) and the number of O atoms of the orthosilicate derived oligomer. The chemical bond crosslinks chains of the orthosilicate derived oligomer to increase mechanical strength of the structural material, relative to the structural material formed without the chemical bond to crosslink the chains, among other benefits described herein.

  • Publication number: 20120114847
    Abstract: SiO2 slurry for the production of quartz glass contains a dispersion liquid and amorphous SiO2 particles with particle sizes to a maximum of 500 ?m. The largest volume fraction is SiO2 particles with particle sizes of 1 ?m-60 ?m, as well as SiO2 nanoparticles with particle sizes less than 100 nm constituting 0.2-15% volume by weight of the entire solids content. To prepare the slurry for use and optimize its flow behavior for later processing by dressing or pouring the slurry mass, and for later drying and sintering without cracks, the slurry has SiO2 particles with a multimodal distribution of particle sizes, with a first maximum in the range 1 ?m-3 ?m and a second maximum in the range 5 ?m-50 ?m, and an 83%-90% solids content by weight of the SiO2 particles and the SiO2 nanoparticles together.

    Abstract: A process for obtaining a structure having a textured external surface for an organic light-emitting device, which structure includes a mineral glass substrate having a surface which is provided with projections and depressions, the process including the deposition of an etching mask on the surface of the substrate and the etching of the surface of the substrate around the etching mask, and possible removal of the mask, wherein one of the steps of preparing the etching mask consists in forming a multitude of nodules randomly arranged on the surface of the substrate and made of a material possessing no affinity with the glass and wherein, after the etching step, the structure undergoes a moderating step in which the slopes of the projections of submicron height and width obtained by etching are moderated sufficiently to form the thus moderated textured external surface.

  • Patent number: 7921672
    Abstract: A method for manufacturing a GRIN lens includes the steps of forming a wet gel provided with a concentration distribution having a different concentration of a refractive index distribution imparting metal that differs in concentration in a radial direction, drying the wet gel to form a dry gel having a bulk specific gravity ? (g/cm3), sintering the dry gel to form a GRIN lens base material and stretching the GRIN lens base material while heating. The method is characterized in that, in the step of sintering the dry gel, partial pressures of oxygen during sintering at 800° C. or higher are 10?1 Pa or lower and also the relation between a rate of temperature increase v (° C./hr) and a bulk density ? of the dry gel during sintering at 1,000 to 1,150° C. is defined by v?105*EXP (?12?). As a result of this, the GRIN lens, which has a large numerical aperture and a small diameter, can stably and easily be manufactured.
