    摘要: Provided is a method and structure for utilizing advance channel substrate materials in semiconductor manufacturing. Advanced channel substrate materials such as germanium and Group III-V channel substrate materials, are advantageously utilized. One or more capping films including at least a nitride layer are formed over the channel substrate prior to patterning, ion implantation and the subsequent stripping and wet cleaning operations. With the capping layers intact during these operations, attack of the channel substrate material is prevented and the protective films are easily removed subsequently. The films are dimensioned in conjunction with the ion implantation operation to enable the desired dopant profile and concentration to be formed in the channel substrate material.

    摘要: Non-planar transistors and methods of fabrication thereof are described. In an embodiment, a method of forming a non-planar transistor includes forming a channel region on a first portion of a semiconductor fin, the semiconductor fin having a top surface and sidewalls. A gate electrode is formed over the channel region of the semiconductor fin, and an in-situ doped semiconductor layer is grown on the top surface and the sidewalls of the semiconductor fin on opposing sides of the gate electrode using a selective epitaxial growth process. At least a part of the doped semiconductor layer is converted to form a dopant rich region.

    摘要: A system and method for aligning a probe, such as a wafer-level test probe, with wafer contacts is disclosed. An exemplary method includes receiving a wafer containing a plurality of alignment contacts and a probe card containing a plurality of probe points at a wafer test system. A historical offset correction is received. Based on the historical offset correct, an orientation value for the probe card relative to the wafer is determined. The probe card is aligned to the wafer using the orientation value in an attempt to bring a first probe point into contact with a first alignment contact. The connectivity of the first probe point and the first alignment contact is evaluated. An electrical test of the wafer is performed utilizing the aligned probe card, and the historical offset correction is updated based on the orientation value.

    摘要: A wafer handling system with apparatus for transporting wafers between semiconductor fabrication tools. In one embodiment, the apparatus is a loadport bridge mechanism including an enclosure having first and second mounting ends, a docking port at each end configured and dimensioned to interface with a loadport of a semiconductor tool, and at least one wafer transport robot operable to transport a wafer between the docking ports. The wafer transport robot hands off or receives a wafer to/from a tool robot at the loadports of a first and second tool. The bridge mechanism allows one or more wafers to be transferred between loadports of different tools on an individual basis without reliance on the FAB's automated material handling system (AMHS) for bulk wafer transport inside a wafer carrier such as a FOUP or others.

    摘要: A hologram reticle and method of patterning a target. A layout pattern for an image to be transferred to a target is converted into a holographic representation of the image. A hologram reticle is manufactured that includes the holographic representation. The hologram reticle is then used to pattern the target. Three-dimensional patterns may be formed in a photoresist layer of the target in a single patterning step. These three-dimensional patterns may be filled to form three-dimensional structures or else used in a multi-surface imaging composition. The holographic representation of the image may also be transferred to a top photoresist layer of a top surface imaging (TSI) semiconductor device, either directly or using the hologram reticle. The top photoresist layer may then be used to pattern an underlying photoresist layer with the image. The lower photoresist layer is used to pattern a material layer of the device.
