  • Patent number: 8853438
    Abstract: Formulations of solutions and processes are described to form a substrate including a dopant. In particular implementations, the dopant may include arsenic (As). In an embodiment, a dopant solution is provided that includes a solvent and a dopant. In a particular embodiment, the dopant solution may have a flashpoint that is at least approximately equal to a minimum temperature capable of causing atoms at a surface of the substrate to attach to an arsenic-containing compound of the dopant solution. In one embodiment, a number of silicon atoms at a surface of the substrate are covalently bonded to the arsenic-containing compound.

  • Publication number: 20140137894
    Abstract: A process is described that is useful for removing organic substances from substrates, for example, electronic device substrates such as microelectronic wafers or flat panel displays. A process is presented for applying a minimum volume of a chemical stripping composition as a coating to the inorganic substrate whereby sufficient heat is added and the organic substances are completely removed by rinsing. The process may be suitable for removing and, in some instances, completely dissolving photoresists of the positive and negative varieties, and especially negative dry film photoresist from electronic devices.

  • Publication number: 20140142017
    Abstract: Compositions are described that are useful for removing organic and organometallic substances from substrates, for example, photoresist wafers. Processes are presented that apply a minimum volume of a composition as a coating to the inorganic substrate whereby sufficient heat is added and the organic or organometallic substances are completely removed by rinsing. The compositions and processes may be suitable for removing and, in some instances, completely dissolving photoresists of the positive and negative varieties, and specifically negative dry film photoresist from electronic devices.

  • Publication number: 20140141622
    Abstract: Processes are described to etch metals. In an embodiment, a process may include contacting a substrate with a stripping solution to remove photoresist from the substrate to produce a stripped substrate. The stripped substrate may include a plurality of solder pillars and a plurality of metal-containing field regions disposed around the plurality of solder pillars. In an illustrative embodiment, the plurality field regions may include copper. Additionally, the process may include rinsing the stripped substrate to produce a rinsed substrate. The rinsed substrate may be substantially free of a Sn layer or a Sn oxide layer. Further, the process may include contacting the rinsed substrate with an etch solution that is capable of removing an amount of one or more metals from the plurality of field regions.

  • Publication number: 20140137899
    Abstract: Processes are described to remove substances from substrates. In an embodiment, a process may include providing a substrate including a first side and a second side with a substance being disposed on at least a portion of the first side of the substrate. The process may also include contacting the substrate with a solution such that the first side of the substrate is coated with the solution, at least a portion of the second side is free of the solution and at least a portion of the substance is released from the first side of the substrate. Additionally, the process may include rinsing the substrate to remove at least a portion of the substance released from the first side of the substrate.
