摘要:
A surface of an insulating workpiece is implanted to form either hydrophobic or hydrophilic implanted regions. A conductive coating is deposited on the workpiece. The coating may be a polymer in one instance. This coating preferentially forms either on the implanted regions if these implanted regions are hydrophilic or on the non-implanted regions if the implanted regions are hydrophobic.

Methods of affecting a material's properties through the implantation of ions, such as by using a plasma processing apparatus with a plasma sheath modifier. In this way, properties such as resistance to chemicals, adhesiveness, hydrophobicity, and hydrophilicity, may be affected. These methods can be applied to a variety of technologies. In some cases, ion implantation is used in the manufacture of printer heads to reduce clogging by increasing the materials hydrophobicity. In other embodiments, MEMS and NEMS devices are produced using ion implantation to change the properties of fluid channels and other structures. In addition, ion implantation can be used to affect a material's resistance to chemicals, such as acids.

摘要:
A method of processing a substrate having horizontal and non-horizontal surfaces is disclosed. The substrate is implanted with particles using an ion implanter. During the ion implant, due to the nature of the implant process, a film may be deposited on the surfaces, wherein the thickness of this film is thicker on the horizontal surfaces. The presences of this film may adversely alter the properties of the substrate. To rectify this, a second process step is performed to remove the film deposited on the horizontal surfaces. In some embodiments, an etching process is used to remove this film. In some embodiments, a material modifying step is used to change the composition of the material comprising the film. This material modifying step may be instead of, or in addition to the etching process.

A plasma processing tool is used to deposit material on a workpiece. For example, a method for conformal deposition of material is disclosed. In this embodiment, the plasma sheath shape is modified to allow material to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of different features can be deposited onto. In another embodiment, a plasma processing tool is used to etch a workpiece. In this embodiment, the plasma sheath shape is altered to allow ions to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of differently shaped features can be created.
