Abstract: A photoresist is applied to a front surface of a semiconductor wafer rotating at a predetermined rotational speed and a photoresist film having a predetermined thickness is formed and dried. Next, a chemical is dripped while the semiconductor wafer is rotated at the predetermined rotational speed or less, whereby an edge part of the photoresist film is dissolved and removed by the chemical while the predetermined thickness of the photoresist film is maintained. A predetermined pattern is transferred to the photoresist film by exposure and development. After the development, without performing UV curing or post-bake, the photoresist film is used as a mask and helium irradiation having a range of 8 ?m or greater from the front surface of the semiconductor wafer is performed. Thus, a predetermined impurity may be implanted with good positioning accuracy in a predetermined region, using the photoresist film as a mask and cost may be reduced.

Abstract: A first semiconductor die and a second semiconductor die can be bonded in a manner that enhances alignment of bonding pads. Non-uniform deformation of a first wafer including first semiconductor dies can be compensated for by forming a patterned stress-generating film on a backside of the first wafer. Metallic bump portions can be formed on concave surfaces of metallic bonding pads by a selective metal deposition process to reduce gaps between pairs of bonded metallic bonding pads. Pad-to-pad pitch can be adjusted on a semiconductor die to match the pad-to-pad pitch of another semiconductor die employing a tilt-shift operation in a lithographic exposure tool. A chuck configured to provide non-uniform displacement across a wafer can be employed to hold a wafer in a contoured shape for bonding with another wafer in a matching contoured position. Independently height-controlled pins can be employed to hold a wafer in a non-planar configuration.
