    摘要: A metal interconnect fabrication process for hybrid solid state systems such as thermal imaging system (50). A plurality of vias (62) are formed in a focal plane array (60) between the thermal sensors (20) to expose a corresponding array of contact pads (84) on a silicon processor (80) bonded to the focal plane array (60). A metal film layer (30) is disposed on the focal plane array (60) to fill the vias (62). Photoresist material (32) is patterned on the metal layer (30) to correspond with the desired sensor signal flow path. With the photoresist material (32) still in place, the metal layer (30) is dry etched to produce the desired metal interconnect pattern by removing portions of the metal layer (30) unprotected by the photoresist material (32).

    摘要: A process is disclosed through which vias (50) can be formed by the reaction of an etchant species (52) with a mercury cadmium telluride (HgCdTe) or zinc sulfide (ZnS) layer (42). The activating gases (20) are preferably a hydrogen gas or a methane gas which is excited in a diode plasma reactor (100) which has an RF power source (13) applied to one of two parallel electrodes. The etching occurs in selected areas in a photoresist pattern (44) residing over the ZnS or HgCdTe layer (42). Wet etching the layer (42) with a wet etchant (54) following the dry etching, improves the via (50) by making the walls (48) smoother, and allowing for expansion of the vias (50) to a dimension necessary for proper operation of a HgCdTe-based infrared detector.

    摘要: A processing apparatus and method wherein a wafer is exposed to activated species generated by a first plasma which is separate from the wafer, but is in the process gas flow stream upstream of the wafer, and is also exposed to plasma bombardment generated by a second plasma which has a dark space which substantially adjoins the surface of the wafer. The in situ plasma is relatively low-power, so that the remote plasma can generate activated species, and therefore the in situ plasma power level can be adjusted to optimize the plasma bombardment. Ultraviolet light to illuminate the face of a wafer being processed is generated by a plasma which is within the vacuum chamber but is remote from the face of the wafer. It is useful to design the gas flow system such 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 is usefully included between the ultraviolet plasma space and the processing space near the wafer face, so that the ultraviolet plasma can be operated at a vacuum level slightly different from that used near the wafer face, delete but this transparent window is not made thick enough to act as a full vacuum seal.

    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 workpiece or wafers which may be loaded into the chamber. HgCdTe is passivated by utilizing oxygen and water vapor for oxidation or a source of sulfur for sulfidization. The wafers and the gases are heated by a heater located on the vertical walls of the process chamber.

    摘要: The disclosure relates to an infrared detector and method of making an infrared detector having HgCdTe detectors in the same focal plane of different compositions responsive to two or more different infrared frequency windows. This is accomplished by using SiO.sub.2 and/or Si.sub.x O.sub.y N.sub.z for masking and/or isolation during liquid phase epitaxial growth of the HgCdTe. The SiO.sub.2 and/or Si.sub.x O.sub.y N.sub.z are formed by plasma deposition.
