Abstract: A for fabricating a semiconductor device comprises forming a mask layer on a substrate, the mask layer defining a through hole that exposes an upper surface of the substrate, the mask layer comprising a first mask layer and a second mask layer, wherein the second mask layer is between the substrate and the first mask layer, and wherein the second mask layer comprises carbon. The method includes forming a liner layer on side walls of the through hole inside the second mask layer.

Abstract: The present invention relates to a barbecuing cooker by which coffee beans, beans, corns or popcorns can be parched beside a convenient barbecue cooking of chickens, turkeys, ducks, steak, fishes and the like, in which far infrared rays can be emitted during cooking to provide a quality meat with excellent taste and nutrition and which is so constructed as to permit easy cleaning of the cooking chamber as well as handy mounting or dismounting of spits.

Abstract: A barbecuing cooker uses infrared rays to cook the food contained therein to provide excellent taste and nutrition and to permit easy cleaning of the cooking chamber as well as handy mounting or dismounting of spits. The barbecuing cooker comprises a main body with side and rear reflecting plates as the inner walls of a cooking chamber, an upper and lower door for opening or closing the inlet opening of the cooking chamber, a ceramic heater, spits provided rotatably through gear wheels, a motor for operating the gear wheels, a control panel for controlling the ceramic heater and motor, an oil receiver and a parching cage.

Abstract: The barbecuing cooker according to the invention comprises a main body(10) with side and rear reflecting plates(20 and 30) as the inner walls of a cooking chamber(11); an upper and lower door(40 and 50) for opening or closing the inlet opening of the cooking chamber(11); a ceramic heater(60) mounted on the rear reflecting plate(30); spits(80) provided rotatably through gear wheels(70) positioned at the central areas of the opposite side reflecting plates(20); a motor(100) for operating the gear wheels(70) by means of a driving gear(90); a control panel(C) for controlling the ceramic heater(60) and motor(100); an oil receiver(110) provided at a lower part of the cooking chamber(11); and a parching cage(120) in substantially a cylindrical form, said parching cage having a cover(121) and said parching cage having a circumferential surface formed with a plurality of small holes(122) and with axial spit grooves(123) at opposite sides, said spit grooves resulting in the formation of inward protuberances(124).
