Patent EP-0564848-A1 (EP)
Inventor: DHONG SANG HOO
IPC: H01L21/8242
Filed: 1993-03-15
Abstract: A method is disclosed for fabricating a DRAM trench capacitor with multiple-pillars inside the trench for increased surface area. 
     A thin pad oxide (12) of a few tens of nonometers is grown on a silicon substrate (10). A layer of silicon nitride (14) is deposited and another layer of oxide (16) is then deposited. Then a layer of polysilicon (18), a layer of nitride (20), and a layer of large-grained polysilicon (22) are deposited sequentially. Then, the trench is defined by a lithographic mask (24) and the exposed large-grained polysilicon (22) is etched in  CF ₄. Since  CF ₄ etches the polysilicon and nitride (20) at almost the same rates, the topographical features existed in the polysilicon layer (22) is copied to the nitride layer (20). The nitride layer is partially etched. The RIE etching gas is then changed to a mixture of HBR,  SiF ₄, Helium, and  NF ₃ which gives a very directional polysilicon etching with a good selectivity to nitride and a very high selectivity to oxide. Consequently, the topographical features on the nitride layer (20) is enhanced and is transferred to the polysilicon layer (18) which is used as a mask to etch the oxide (16) nitride (14) and pad oxide (12) to form pillars. 
     Using the polysilicon material left as a mask, the CVD oxide, nitride, and pad oxide are sequentially etched in a mixture of  CF ₃ H  and  CO ₂ which etches nitride and oxide with a good selectivity to polysilicon and silicon substrate. 
     Next, the lithographical mask is removed and the silicon substrate is etched. The portion of the three polysilicon-nitride-polysilicon layers is now exposed and is removed leaving behind only the CVD oxide layer. 
     The CVD oxide, nitride, and pad oxide on top of the resultant silicon pillar are removed by wet etching the pad oxide in a buffer HF. 
     The pillars are then recessed below the silicon substrate level using silicon-etching RIE, the CVD oxide 16 is removed in BHF or RIE, an oxide-nitride-oxide (ONO) layer is grown and deposited as a capacitor interdielectric, and polysilicon 28 is deposited and chemical-mechanically polished using the nitride layer as stopping layer.

Abstract: A cutting tool consists of a basic body (1) with a stop pin (10) and a clamping screw (5, 6) as well as of an exchangeable cutting tip (3, 4). The latter are recessing cutting tips which are made of various cutting materials as single- or double-edged finish-cutting tips for the various types of recess such as, for example, O-rings, hydraulic bevels, undercuts and the like for materials to be machined in different ways. Due to the frictional and positive-locking clamping, grooves can also be cut out and even turning work can be carried out with this recessing tool. <IMAGE>

Abstract: The invention relates to a connecting device, especially for a tubular component (22) which has at least one connecting end which has a recess (21) and can be connected to a connecting end of another component (32) by means of an invisible connection, which can preferably be produced by screws, to form a butt joint (37). In order to achieve simple assembly and dismantling, the connecting device contains a part (1) (which can be inserted into the recess, can be spread and is constructed in the form of a sleeve), an expanding part (17) having an expanding surface which interacts over a large area with a correspondingly constructed surface of the part which can expand, and a (10) which is intended for tightening the expanding part in the part which can spread, is constructed as a continuous threaded bolt and is expediently screwed into an internal-threaded section in the expanding part. In order that the bolt (10) cannot be unscrewed against, without any further action, once the expanding part has been tightened, the expanding part (17) and/or the bolt (10) is preferably provided with a first rotation prevention device which makes it impossible or difficult to unscrew the bolt (10). In consequence, it is possible to construct the bolt (10) as, for example, a normal threaded bolt. Once this threaded bolt has been screwed into the expanding part, it can be tightened in the part which can spread such that, for example, a defined tensile force is exerted on the bolt by means of an electric screwdriver.

Abstract: Methods and apparatus for collecting gasses from the sample headspace (52) of a sealed sample container (50) are disclosed. The gasses in the sample headspace (52) are withdrawn by inserting a probe (110) into the sample headspace (52) and permitting the gasses to flow into an external headspace (102). The probe (110) is then disconnected from the sample to seal the external headspace (102) and the external headspace (102) is then connected to the analytical instrument such as a gas chromatograph (210) to permit the sample gasses to be transferred out of the external headspace (102) an into the instrument (210). The step of transferring the gasses is preferably accomplished by connecting a source of carrier gas (200) to an inlet port (103) of the external headspace (102) and sweeping the sample gasses from the external headspace (102).

Abstract: Perfluorotripentylamine, perfluoropolyether or another such high-boiling liquid is added as a foaming agent to a thermoplastic fluororesin such as a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin or a tetrafluoroethylene-hexafluoropropylene copolymer resin. Because the vapor pressure of said foaming agent in the molten fluororesin is lower than that of Freon or another such low-boiling foaming agent, the cells in the foam can be made fine and uniform in diameter.

The A side composition comprises a polyfunctional isocyanate compound and a free radical initiator. The B side composition comprises a mixture of: (i) an ethylenically unsaturated monomer solution having dissolved therein about 30-90 weight percent of a polyester polyol having at least one ethylenically unsaturated group per molecule which has predominantly hydroxyl end groups; (ii) an amine compound having two or more primary or secondary amine groups in an amount effective to react with the A side composition to form small urea domains finely dispersed within a continuous polyester-polyurethane hybrid phase; and (iii) about 25 to about 150 equivalents water based on 100 equivalents of active hydrogen in the B side. When the A and B side compositions are reacted, the composition will have a ratio of active NCO groups of the isocyanate to active NH groups of the amine compound of between about 10:1 and about 50:1, and an isocyanate index, NCO:(NH + OH + COOH + HOH), of between about 0.5 and about 2.0.
