IPC: G02B6/12
Filed: 2002-12-24
Abstract: PURPOSE: A method for integrating an active optical device and a passive optical device, and an integrated device thereby are provided to form the active optical device and the passive optical device on one substrate by changing a buried ridge waveguide into a strip loaded waveguide. CONSTITUTION: A taper is formed at an end of a passive waveguide connected to a buried ridge waveguide of an active device in order to change the taper into the strip loaded taper when a center of the buried ridge waveguide of the active device is etched. The taper is covered by a re-growth process. The taper is arranged to the taper formed at an end of the buried ridge waveguide. The strip-loaded waveguide is formed by performing an etching process. An etch-stop layer is inserted in the process for growing the passive waveguide layer in order to form constantly the etching depth.

Abstract: PURPOSE: A semiconductor device and a manufacturing method thereof are provided to prevent the exposure of a metal line for a fuse by improving the etching rate of TiN and reducing simultaneously the etching rate of an oxide layer using plasma processing with CF4 and O2 gas in an ashing process. CONSTITUTION: A semiconductor device(100) is divided into a pad region(110) and a fuse region(120). The pad region includes a lower metal line(112), a plug(113) and an upper metal line(114). The fuse region includes metal lines(122) for a fuse. An oxide layer(140) and a nitride layer(150) are sequentially formed on the resultant structure. The pad region is exposed by etching selectively the nitride layer and the oxide layer using a predetermined photoresist pattern(160). At this time, the oxide layer exists on the fuse region. Ashing is performed on the resultant structure by using O2 gas of 12000 sccm. CF4 gas of 200-600 sccm is added to the O2 gas.

A two-row seat folding device for a recreational vehicle comprises a down-folding device(50) for making the rear side of a seat back and a bottom surface the horizon by moving down the seat cushion in folding the seat back and a double-folding device for making people get on and out of a three-row seat with one lever. The down-folding device is composed of front and rear links(54,55) for connecting four front and rear sides of the cushion frame and four front and rear sides of a cushion plate to freely move and a diving lever(60) having a lower side connected in the middle of the rear link and an upside linked with an upper tooth bracket(57) moving about a recliner shaft(56) of the recliner. The diving lever prevents movements of the front and rear links and dives and folds the seat cushion by pushing and folding the front and rear links in folding the seat back. The double-folding device comprises a lever body(71) of which a central part is hinge-fixed to a lever bracket(70) disposed in the upper end of the seat back frame and a gas lift fixed between the supporting plate and a lever projected downward a space holding bar connected horizontally from the rear side of the cushion frame to facilitate a double-folding and lift the whole seat.
