It is another object of the present invention to provide a technique for etching trenches which alleviates loading problems associated with etching trenches of different sizes (widths). While a prisoner in Spain, Baron Lejuene penned this arresting picture of military impedimenta in his time: the first layer is a single or multi-layer of materials selected from the group of silicon dioxide and silicon nitride. Furthermore, in the case of trenches having different sizes (widths), loading effects are uneven and the various size trenches will not etch to the same depth. It is another object of the present invention to provide a built-in endpoint detection mechanism in the trench etching process. using a batch reactor), etch rate must be very well controlled, and usually must be measured immediately prior to etching. The present invention relates to the fabrication of semiconductor devices and, more particularly, to techniques for forming trenches, such as for isolation structures. ” First came the captain in his scarlet uniform, mounted on a very fine horse and carrying a big open parasol. applying a second non-patterned layer of a second material, dissimilar from the first material, over the first non-patterned layer; in a first etching step, etching holes through the first and second non-patterned layers directly atop selected areas in the substrate, and exposing a surface of the substrate underlying the first layer, said first etching step being conducted as an anisotropic plasma etch employing a chlorine containing gas and hydrogen bromide; It is therefore an object of the present invention to provide an improved technique for etching trenches, particularly shallow isolation trenches (e.g. Then came his wife in a pretty costume, with a very small straw hat, seated on a mule, holding up an umbrella and caressing a little black and tan King Charles spaniel on her knee, whilst she led by a blue ribbon a tame goat, which was to supply her night and morning with cream for her, cup of tea. Beside madam walked an Irish nurse, carrying slung across her shoulder a bassinet made of green silk, in which reposed an infant, the hope of the family. In both cases, loading effects during the second etch step are alleviated, or completely eliminated, because both the upper layer and the substrate are silicon-based materials. Again, it is preferable that the materials for the two layers of the two-layer trench mask be selected so that the top layer of the trench mask etches substantially uniformly with the initial layer, and the bottom layer of the trench mask is a dissimilar material providing convenient endpoint detection for the second etch step. plasma etched) into the substrate around the active regions to a depth “d” of from a few hundred Angstroms (в„«) to a few microns (Ојm). Additionally, while trench depth can be measured with a stylus, such a measuring technique is both slow and destructive. in a second, subsequent etching step, etching the second layer and the substrate until the first layer is exposed, thereby forming trenches in the substrate; Behind him again came a donkey laden with the voluminous baggage of the family, surmounted by a tea-kettle and a cage full of canaries, whilst a jockey or groom in livery brought up the rear, mounted on a sturdy English horse, with its hide gleaming like polished steel. A method of forming isolation trenches adjacent active areas in semiconductor devices, consisting of essentially: Commonly, the resulting trenches are overfilled with silicon dioxide (“oxide”), and excess oxide (that which is not within the trench) is removed, such as by polishing–as disclosed in commonly-owned, copending U.S. This groom held a huge posting whip in one hand, the cracking of the lash of which made the donkey mend its pace, and at the same time kept order among the four or five spaniels and greyhounds which served as scouts to the captain during the march of his small cavalcade. Ultimately, the trench will be filled with an insulating material, and will form an isolation structure. But hardly more ridiculous than the look of the United States Army when it moves abroad loaded with all of the comforts A lean and strong-going rifleman cannot spring fully armed and ready from the brow of an army that is elsewhere rolling in fat. white trench coat trench coat beige leather trench coat red trench coat trenchcoat wool trench coat trench beige parka brown trench coat the trench black pea coat women womens long winter coats womens trench coats trench coat men black trench coat womens trench coat ladies trench coat trench coat life in the trenches trench coat women long trench trenchcoats winter jacket for women mens trench coat long trench coats long trench coat wool pea coat women trench coat classic womens long coats womens raincoats
