Methods and apparatuses are provided for measuring a biometric signal by an electronic device. An object having an animation effect for inhalation and exhalation is displayed. The animation effect includes the object being expanded to guide the inhalation of a user and the object being contracted to guide exhalation of the user. A sensor unit obtains at least one biometric signal related to a heart rate of the user while the object is displayed. A motion of the electronic device is detected having a strength that is greater than or equal to a threshold strength. Based on the motion ceasing before exceeding a predetermined time, display of the object and obtaining of the at least one biometric signal is continued. Based on the motion lasting longer than or equal to the predetermined time, the obtaining of the at least one biometric signal and the displaying of the object is terminated.

A method of fabricating a micro-lens, and a method of fabricating an optical module using the method are provided. To fabricate a micro-lens, a thin film is formed of a material for the micro-lens on a substrate. A photoresist pattern is formed on the thin film, a thin-film structure is formed by etching the thin film using the photoresist pattern, and the micro-lens is completed by reflow by thermally treating the thin-film structure.

A method of fabricating a planar lightwave circuit (PLC) having an optical waveguide includes the steps of: (b) forming an initial optical waveguide having a predetermined pattern, which is a transmission medium of light, on a substrate; and (c) reflowing the optical waveguide by applying heat thereto.

Planar lightwave circuit and fabrication method thereof

A wafer boat for consolidation of a porous oxide layer structure is provided. The wafer boat includes at least one support plate including: a first plate for supporting a substrate with the porous oxide layer by face-to-face contact; a second plate radially extending from a periphery of the first plate; and a stepped portion for limiting movement of the substrate formed with a predetermined height along a border line between the first plate and the second plate. The wafer boat also includes a support plate supporting the edge of the wafer to be consolidated, so that it is possible to prevent the porous layer of a wafer located underneath from being damaged by the falling particles from the broken particles from the porous layer of the wafer located at the upper side. Also, the omission of a dummy wafer can reduce the size of the consolidation furnace, and the automation system and the process can be simplified leading to reduction of the production cost. In addition, since a stepped portion is provided for limiting movement of the wafer mounted on the wafer boat, damage to the porous layer of the wafer due to contact of the wafer with the support rod can be prevented.

Wafer boat for consolidation of porous thin layer

A flame stabilizing apparatus is disclosed for application to a burner for a flame hydrolysis deposition (FHD) process. In the flame stabilizing apparatus, a co-flow diffusion flame burner emits a flame onto a substrate and a flame stabilizer, installed around the burner coaxially, isolates the emitted flame from an instable ambient flow to stabilize the flame and a particle flow.
