    摘要: A method of tailoring the dopant profile of a substrate by utilizing two different dopants, each having a different diffusivity is disclosed. The substrate may be, for example, a solar cell. By introducing two different dopants, such as by ion implantation, furnace diffusion, or paste, it is possible to create the desired dopant profile. In addition, the dopants may be introduced simultaneously, partially simultaneously, or sequentially. Dopant pairs preferably consist of one lighter species and one heavier species, where the lighter species has a greater diffusivity. For example, dopant pairs such as boron and gallium, boron and indium, phosphorus and arsenic, and phosphorus and antimony, can be utilized.

    摘要: 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: Methods of creating porous materials, such as silicon, are described. In some embodiments, plasma sheath modification is used to create ion beams of various incidence angles. These ion beams may, in some cases, form a focused ion beam. The wide range of incidence angles allows the material to be deposited amorphously. The porosity and pore size can be varied by changing various process parameters. In other embodiments, porous oxides can be created by adding oxygen to previously created layers of porous material.

    摘要: Methods of enabling the use of high wavelength lasers to create shallow melt junctions are disclosed. In some embodiments, the substrate may be preamorphized to change its absorption characteristics prior to the implantation of a dopant. In other embodiments, a single implant may serve to amorphize the substrate and provide dopant. Once the substrate is sufficiently amorphized, a laser melt anneal may be performed. Due to the changes in the absorption characteristics of the substrate, longer wavelength lasers may be used for the anneal, thereby reducing cost.

    摘要: An improved method of doping a substrate is disclosed. The method is particularly beneficial to the creation of interdigitated back contact (IBC) solar cells. A patterned implant is performed to introduce a first dopant to a portion of the solar cell. After this implant is done, an oxidation layer is grown on the surface. The oxide layer grows more quickly over the implanted region than over the non-implanted region. An etching process is then performed to remove a thickness of oxide, which is equal to the thickness over the non-implanted regions. A second blanket implant is then performed. Due to the presence of oxide on portions of the solar cell, this blanket implant only implants ions in those regions which were not implanted previously.

    摘要: An improved method of creating LED arrays is disclosed. A p-type layer, multi-quantum well and n-type layer are disposed on a substrate. The device is then etched to expose portions of the n-type layer. To create the necessary electrical isolation between adjacent LEDs, an ion implantation is performed to create a non-conductive implanted region. In some embodiments, an implanted region extends through the p-type layer, MQW and n-type layer. In another embodiment, a first implanted region is created in the n-type layer. In addition, a second implanted region is created in the p-type layer and multi-quantum well immediately adjacent to etched n-type layer. In some embodiments, the ion implantation is done perpendicular to the substrate. In other embodiments, the implant is performed at an angle.

    摘要: Semiconductor devices formed on wafers are inspected using a master wafer. A subject wafer of a semiconductor design is provided. The subject wafer has dies wherein semiconductor devices of the semiconductor design are formed and at a stage of fabrication. A current layer of the subject wafer is scanned to obtain a scanned layer/image. A master wafer comprising individual wafer/layer maps is obtained. The scanned layer is compared with a corresponding layer map. Matching and non-matching defects are identified from repetitive defects within the corresponding layer map and defects within the scanned layer. The matching defects are reviewed to classify and or identify causality. The master wafer is then updated.
