摘要:
A plasma processing chamber 10 having an inductively coupled plasma (ICP) source 12 mounted therein. The ICP source 12 comprises an antenna 14 encapsulated in epoxy 16 and surrounded by housing 18. The antenna 14 and epoxy 16 are hermetically sealed from plasma formation region 30. The antenna 14 is powered by at least one RF power supply 40 through at least one RF matching network 42. Dielectric capping plate 28 separates ICP source 12 from the plasma formation region 30 and may have a plurality of holes therein to provide a uniform showerhead distribution of process gases.

摘要:
A thin reflective cylindrical baffle [20] in a radiant lamp heater is provided in the space below a plurality of heating bulbs [2,4,6] (arranged in a center position and around a middle and outer ring) and above a quartz window [12]. The baffle diameter is such that it fits within the annular space between the middle [4] and outer [6]ring of bulbs. The baffle which blocks a predetermined amount of light generated by the lamp bulbs [20] allows improved controllability of wafer temperature profile--for a wafer heated by a radiant lamp heater.
摘要:
A process module which is compatible with a system using primarily vacuum wafer transport, but which permits processing multiple slices in parallel in a single module. This is accomplished by using notched quartz arms in the module, so that the transfer arm can place each of several wafers into one set of notches in the quartz arms. Optionally, a vertical degree of movement in the arm may be used to accomplish this, and the quartz arms may be immovable. This means that the port from the multi-wafer module into the wafer transfer system must be high enough to accommodate the necessary vertical movement of the transfer arm. After the transfer arm has placed the wafer on the quartz arms, the process module can be elevated to close around the set of wafers and made a seal. If the wafer transport arm is already configured to access wafers directly out of a multi-wafer vacuum wafer carrier, the necessary degree of freedom will necessarily already be present in the transfer arm, and at least one port of the necessary vertical dimensions will necessarily also be already present (between the loadlock and the transfer chamber). This is particularly useful in combination with relatively slow processes, such as thick field oxidation, long anneals, or long furnace heating steps used to drive in diffusions.
摘要:
A processing apparatus and method for edge-preferential processing of partially fabricated integrated circuit wafers or of other substantially flat and thin workpieces. A plasma remote from the workpiece is used to generate activated species, and a baffle which is in proximity to the wafer face but not in contact with it is used to direct the stream of activated species. This module can be set up to perform both edge bead removal and bake of spun-on photoresist.
摘要:
A plasma reactor with in situ ultraviolet generation processing aparatus and method. Ultraviolet light to illuminate the face of a wafer being processed is generated by a plasma which is within the vacuum processing chamber but is remote from the face of the wafer. It is useful to design the gas flow system so that the ultraviolet-generating plasma has its own gas feed, and the reaction products from the ultraviolet-generating plasma do not substantially flow or diffuse to the wafer face. A transparent isolator between the ultraviolet plasma space and the processing space near the wafer face is useful so that the ultraviolet plasma can be operated at a vacuum level slightly different from that used near the wafer face, but this transparent window is not made thick enough to act as a full vacuum seal. Optionally, this window may be omitted entirely.
摘要:
A high pressure processing apparatus and method which is compatible with a system wherein wafers are largely transported and processed under vacuum. The pressure vessel can be extremely small, i.e. has a total pressurized volume of which almost all interior points are within one or two centimeters of one of the workpieces which may be loaded into the chamber.
摘要:
A radiant heating processing apparatus and method for a rapid thermal processing system, wherein only the base of the reflector module is directly water cooled. The sides of the reflector module are not directly water cooled; instead, the module is made to be a slip fit into a chamber which does have water cooled walls. Thus, in applications where it is desired to be able to fit a rapid thermal processing radiant heating source through a restricted clearance, especially in application where it is desired to be able to insert the module through a vacuum flange, the necessary clearance is reduced by the width which would otherwise be required for water cooling of the sidewalls.
摘要:
A glass heating and sealing system (10, 30, 60) and method for manufacturing a flat panel display including anode and cathode glass panels with a vacuum compartment between them includes a plurality of vacuum chambers (12, 14, 16, 18, 20, 32, 34, 36, 38, 61, 76) for processing glass panels (39, 63, 74). Transfer of glass panels (39, 63, 74) between chambers (12, 14, 16, 18, 20, 32, 34, 36, 38, 61, 76) is accomplished by a transfer mechanism (24, 42, 68, 72) located within a central vacuum chamber (22, 40, 70) commonly connected to the other chambers. System (10, 30, 60) may include a rapid thermal processing (RTP) chamber (14, 34, 38, 76) for quick and even heating of the panels (39, 63, 74). System (10) includes an e-beam bombardment chamber (16) for preconditioning the anode glass panels, and a heating chamber (18) for fusing anode glass panels to cathode glass panels. Different levels of vacuum may be established in different chambers.
摘要:
A processing apparatus and method for transferring wafers or flat workpieces between a controlled vacuum load lock and a non-vacuum transfer mechanism. The apparatus is adapted to receive the wafers in a carrier under vacuum. The load lock chamber of the apparatus is then pumped down and purged, if desired. Next the chamber is brought to ambient pressure and an opening to the chamber is created. A transfer arm within the chamber transfers the wafers from the carrier through the opening and to a platform or an non-vacuum carrier. The wafers are received by the arm outside the chamber and transferred through the opening and placed into the vacuum carrier within the chamber. The opening into the chamber is closed and a vacuum is generated. The chamber can then be purged, if desired and the vacuum carrier sealed. The carrier can now be removed from the load lock chamber.
