Patent EP-1342271-A1 (EP)
IPC: H01L29/24
Filed: 2000-12-11
Abstract: A method of fabricating a self-aligned bipolar junction transistor in a semiconductor structure having a first layer of silicon carbide generally having a first conductivity type and a second layer of silicon carbide generally having a second conductivity type, opposite to the first conductivity type. The method comprises forming a pillar in the second silicon carbide layer, the pillar having a side wall and defining an adjacent horizontal surface on the second layer, forming an oxide layer having a predetermined thickness on the second semiconductor layer, including the side wall and the horizontal surface. After formation of the oxide layer, the oxide layer on a portion of the horizontal surface adjacent the side wall is anisotropically etched while at least a portion of the oxide layer remains on the side wall, thereby exposing a portion of the horizontal surface. A portion of the second layer below the exposed portion of the horizontal surface is then doped with a dopant of the first conductivity type to create a doped well region in the second layer which is spaced from the side wall by a distance defined by the thickness of the oxide layer. Resulting devices are likewise disclosed.

Inventor: SMART DONALD V
IPC: B23K26/06
Filed: 2000-12-19
Abstract: L'invention concerne un procédé et un système à haut rendement énergétique destinés au traitement d'une matière-cible, telles que des microstructures situées dans une région microscopique, n'entraînant pas de changements indésirables dans les caractéristiques électriques et/ou physiques de la matière entourant la matière-cible. Ce système comprend une commande destinée à générer un signal de commande de traitement et un générateur de signal destiné à générer un signal de commande modulé, fondé sur le signal de commande de traitement. Le signal a un temps de montée inférieur à la nanoseconde. Ce système comprend également un laser initiateur à semi-conducteur à impulsions à commutation de gain destiné à générer des trains d'impulsions laser à une certaine fréquence de répétition. Le signal de commande pompe le laser de façon que chaque impulsion du train d'impulsions ait une forme prédéterminée. De plus, ce système comprend un amplificateur laser destiné à amplifier optiquement le train d'impulsions afin d'obtenir un train d'impulsions amplifié, sans changer sensiblement la forme prédéterminée des impulsions. Les impulsions amplifiées ont peu de distortion et ont sensiblement la même distribution d'énergie temporelle relative que le train d'impulsions de départ du laser. Chacune des impulsions amplifiées a une distribution densimétrique d'énergie temporelle sensiblement carrée, un temps de montée très rapide, une durée d'impulsion et un temps de descente. Le système comprend également un sous-système de distribution de faisceau et de focalisation destiné à distribuer et à focaliser au moins une partie du train d'impulsions amplifiées sur la matière-cible. Le temps de montée (inférieur à 1 ns environ) est suffisamment rapide pour coupler efficacement l'énergie du laser à la matière-cible, la durée d'impulsion (généralement 2 à 10 ns) est suffisante pour traiter la matière-cible, et le temps de descente (quelques ns) est suffisamment court pour éviter les changements indésirables de la matière entourant la matière-cible.

Abstract: This invention relates to a process for producing
sustained release microcapsules of water soluble peptides,
usable in injectable preparations and with adjustable release
periods between 1 and 18 weeks, that consist in emulsionning
continuously an active peptide in aqueous solution
into an oily solution of a biodegradable polymer dissolved
in an organic solvent slightly soluble in water, using for
this intention, a first equipment of intensive agitation,
closed to ambient, fed by dosage machines; after being
cold, this first water/oil emulsion is taken by a dosage
machine to a second intensive agitation equipment, air room
closed, where it is continuously emulsified into an aqueous
phase, that contains a protective hydrophilic colloid,
which is fed by a continuous dosage machine to a closed
recipient, where the solvent is evaporated by pressure reduction,
producing the consolidation of microcapsules.
Then, the suspension of microcapsules is sieved, centrifuged,
washed with water, and fractionated into adequate
recipients after dispersion into an aqueous medium that
contains a lyophilizing excipient; then, they are frozen in
an orbital agitation freezer at temperatures below -20°C,
and they are lyophilized into the same recipients.

Abstract: The invention relates to a method for defining or controlling a gene hunting study
which is used to determine certain genetic data. Essentially, what is done is to
specify the loci to have an initial population specifying the loci of reference markers
and the locus of at least one test locus which corresponds to what is postulated to be
the locus where a mutation may be causing a particular disease. The recombination
fraction is obtained between all the loci and with this initial data, a test population of
individuals is generated. This then has a theoretical patient population having the
mutation. This theoretical patient population can then be used to allow an initial
assessment of the gene hunting studies. For example, the theoretical patient
population can be used to carry out the gene hunting study and the results of the gene
hunting study on the theoretical population can then be used to specify and define
actual gene hunting studies. The invention can also be used to test the efficacy of
gene hunting studies.
