  • Patent number: 6419751
    Abstract: In a hot plate for performing heat processing while an inert gas is supplied, a mounting table is provided with a groove and a lower end portion of a lid body can be inserted into the groove. The lid body is lowered in two steps by a lid body drive apparatus. The lid body forms a processing chamber between the lid body and the mounting table by the lowering of the first step, and the lower end portion of the lid body is inserted into the groove by the lowering of the second step, thereby reducing the processing chamber in capacity. Consequently, in a substrate processing apparatus which requires a supply of gas, it becomes possible to reduce the capacity of the processing chamber and to reduce the required amount of gas.

  • Publication number: 20020090464
    Abstract: Particulate contamination can occur in physical vapor deposition (PVD) systems when sputtered target material accumulates on the walls of the processing chamber and flakes off onto the workpiece. In a method for preparing a shield to reduce particulate contamination, sheet metal is formed to conform to the surfaces of the deposition chamber. The base metal is roughened, such as by sand blasting. A layer of coating material, whose coefficient of thermal expansion (CTE) is similar to that of the target material, is applied to the roughened base metal surface by a thermal spraying process. The surface of the coating is very rough, more than five times rougher than the underlying base metal texture. When the coating CTE and surface roughness are chosen carefully, shield performance can be optimized, resulting in longer processing times between shield replacements, reduced PVD chamber maintenance and less down time in these systems.

  • Publication number: 20020056417
    Abstract: A substrate processing apparatus comprises a heating process chamber in which a heating process is performed for a wafer, a load lock chamber, connected to the heating process chamber, for controlling at least oxygen concentration and pressure, a transferring arm transferring the wafer between the heating process chamber and the load lock chamber, and a gate valve shielding the heating process chamber from the load lock chamber. Thus, an insulation film with high quality can be formed. In addition, the wafer is temporarily placed in the load lock chamber adjacent to the heating process chamber without need to be transferred to another unit. Thus, the transferring time period for the wafer can be shortened. In addition, footprints can be decreased.

    Abstract: A high pressure chamber comprises a chamber housing, a platen, and a mechanical drive mechanism. The chamber housing comprises a first sealing surface. The platen comprises a region for holding the semiconductor substrate and a second sealing surface. The mechanical drive mechanism couples the platen to the chamber housing. In operation, the mechanical drive mechanism separates the platen from the chamber housing for loading of the semiconductor substrate. In further operation, the mechanical drive mechanism causes the second sealing surface of the platen and the first sealing surface of the chamber housing to form a high pressure processing chamber around the semiconductor substrate.

  • Patent number: 6372048
    Abstract: A resistance heating element 33 for heating a wafer W is embedded within a ceramic heater 22 that forms a susceptor for a semiconductor wafer W to be processed, and power lines 35 from the resistance heating element 33 extend out of the processing chamber 20. A sheathing bellows 38 that houses the power lines 35 in an insulated state is interposed between the ceramic heater 22 and a base plate 24 of the processing chamber 20, and an end piece 39 of the sheathing bellows 38 is connected by screws 40 to the ceramic heater 22 to provide a space 50 therebetween. The screws 40 are such as to permit the thermal expansion of the sheathing bellows 38. This configuration makes it possible to make the temperature distribution in the surface of the semiconductor wafer uniform and thus improve the uniformity of film formation, and also prevent corrosion of components such as the power lines and terminals, and suppress the generation of particles.

  • Publication number: 20020038528
    Abstract: A sealable door assembly including a frontplate which faces an opening to be sealed, a backplate operatively coupled to the frontplate, and at least one inflatable member located between the frontplate and the backplate. When inflated, the inflatable member moves the frontplate into sealing engagement with the opening. In one embodiment the inflatable member includes one or more vacuum grade bellows. A movable mechanism moves the door assembly to selectively occlude the opening. Once the door assembly occludes the opening, the inflatable member is inflated and expands forcing the frontplate in a direction normal to the opening, thereby sealing the opening. The door assembly may be mounted within a pocket formed in an outer wall of a transfer chamber, and a sealing plate may be employed to form a gas tight region within the pocket. The gas tight region may be pressurized to enhance the door's seal of the opening.

    Abstract: An etching apparatus for manufacturing semiconductor devices which reduces contamination of the processing surface of a wafer by transporting a plurality of wafers stacked in a cassette with their processing surfaces facing down from the cassette supply chamber to one or more process chambers where the etching operation is performed on each wafer, one at a time. The apparatus has a load lock chamber for transferring the wafers stacked in the cassette from the cassette supply chamber, which is maintained under atmospheric conditions, to the process chamber, which is maintained under a strong vacuum. The process chamber has a cathode to which a wafer is clamped by a wafer holder with its processing surface facing down; the process chamber may also have a removable lower cover for easy repair and cleaning.

  • Patent number: 6338778
    Abstract: The invention relates to a device, in particular for a laser-induced vacuum are discharge evaporator for depositing of multiple layers with a high level of purity and high deposition rates on large-area components. According to the invention, the material source for the coating material is in a source chamber which can be evacuated and can be separated in a vacuum-tight manner from the actual coating chamber in which the substrate to be coated is located. The evaporator can, in particular, be used for deposition of amorphous carbon layers which are hydrogen-free and superhard and/or which contain hydrogen, in conjunction with high-purity metal layers or for the reactive plasma-enhanced deposition of, for example, oxidic, carbide, nitride hard material layers of ceramic layers or a combination thereof. The corresponding plasma sources can be flange-mounted on any suitable coating chambers and, consequently, also combined with conventional coating processes, for example magnetron sputtering.
