  • Patent number: 10665740
    Abstract: Disclosed is a thin film type solar cell which prevents short circuit from occurring between a first electrode and a second electrode due to a burr produced in a separation part, thereby preventing an output from being reduced. The thin film type solar cell includes a substrate, a first electrode disposed over the substrate and being apart from an adjacent first electrode by a first separation part, a semiconductor layer disposed over the first electrode and being apart from an adjacent semiconductor layer by a contact part and a second separation part, and a second electrode disposed over the semiconductor layer and being apart from an adjacent second electrode by the second separation part. The semiconductor layer contacts the substrate through the first separation part, and the second electrode contacts the first electrode through the contact part. A height of a burr produced in the second separation part is lower than a height between the first electrode and the second electrode.

  • Patent number: 7465672
    Abstract: The present invention relates to a method of forming an etching mask. According to the present invention, there is provided a method of forming an etching mask, comprising the steps of: depositing a hard mask film containing silicon on a substrate; depositing a photoresist on the hard mask film; patterning the photoresist; and etching the hard mask film using the photoresist pattern as an mask and using an etching gas including a CHxFy(x, y=1, 2, 3) gas. At this time, an etch selectivity of the hard mask film to the photoresist pattern can be increased using a mixed gas including CH2F2 and H2 gases when etching the hard mask film under the photoresist pattern used in a wavelength of 193 nm or less.

  • Publication number: 20030162885
    Abstract: Disclosed is a glass resin ceramic (GRC) composition and method of producing the same. The GRC composition is based on a waste thermoplastic synthetic resin formulated with waste ceramic and/or waste glass. The GRC composition has higher tensile strength, bending strength and durability than do the conventional concrete compositions obtained from an admixture of flyash and slag. Also, the GRC composition shows high dimensional stability such that, when it is used to construct large-size products, uniform quality is guaranteed. Thanks to its high specific gravity, the GRC composition can be applied for the production of the products which need a considerable weight. Further, desired colors can be expressed in the composition. Reuse of waste ceramics and glass will give contribution to settlement of environmental pollution.
