Abstract: A laser light source is provided including an airtight container. A first resonance mirror and a second resonance mirror are disposed outside the airtight container. The first resonance mirror includes a lens unit and a reflection coating layer. The lens unit includes a first surface and a second surface, and the first surface is inclined with respect to the second surface.

Abstract: A display device includes a pixel disposed in a display area. The pixel includes first and second sub-areas; first and second electrodes of a first stage disposed in the first sub-area; first light emitting elements disposed between the first and second electrodes; first and second contact electrodes of the first stage to electrically connect the first light emitting elements between the first and second electrodes; first and second electrodes of a second stage disposed in the second sub-area; second light emitting elements disposed between the first and second electrodes of the second stage; first and second contact electrodes of the second stage to electrically connect the second light emitting elements between the first and second electrodes of the second stage; and a connection electrode to electrically connect the second contact electrode of the first stage with the first contact electrode of the second stage.

Abstract: A cleaning solution for preventing the collapse of photoresist patterns and a method of cleaning a semiconductor device using the cleaning solution; the cleaning solution includes a solvent and a surfactant and has a dynamic surface tension of about 50 dyne/cm or less at about 6 bubbles/seconds when measured by a maximum bubble pressure method. The collapse of the photoresist pattern can be prevented using the cleaning solution when forming minute photoresist patterns having about 100 nm or less pattern width. The cleaning solution containing a surfactant in a high concentration also can be prepared to reduce distribution expenses.

Abstract: This invention concerns a method of producing human granulocyte colony-stimulating factor (hGCSF) and human growth hormone (hGH) from least by using recombinant DNA technology. More specifically, this invention relates to a method of producing hGCSF or hGH by using yeast expression vector which contains: hybrid promoters comprising promoters of two different yeast-derived genes, yeast killer toxin leader peptide, and amino terminus of IL-1&bgr;. In addition, this invention relates to a method of producing hGCSF by using expression vector which contains promoter and secretion signal of HSP 150.
