Abstract: An integrated circuit in which measurement of the alignment between subsequent layers has less susceptibility to stress induced shift. A first layer of the structure has a first overlay mark. A second and/or a third layer are formed in the alignment structure and on the first layer. Portions of the second and/or third layer are selectively removed from regions in and around the first overlay mark. A second overlay mark is formed and aligned to the first overlay mark. The alignment between the second overlay mark and first overlay mark may be measured with an attenuated error due to reflection and refraction or due to an edge profile shift of the first overlay mark.

Abstract: A method of performing immersion lithography on a semiconductor substrate includes providing a layer of resist onto a surface of the semiconductor substrate and exposing the resist layer using an immersion lithography exposure system. The immersion lithography exposure system utilizes a fluid during exposure and may be capable of removing some, but not all, of the fluid after exposure. After exposure, a treatment process is used to remove the remaining portion of fluid from the resist layer. After treatment, a post-exposure bake and a development step are used.

Abstract: In a photolithography process, a photoresist layer is formed on a substrate. A photomask is aligned over the substrate to transfer pattern images defined in the photomask on the substrate. The photomask includes first and second patterns of different light transmission rates, and a dummy pattern surrounding the second pattern having a light transmission rate lower than that of the first pattern. The substrate is exposed to a light radiation through the photomask. The photoresist layer then is developed to form the pattern images. The dummy pattern is dimensionally configured to allow light transmission, but in a substantially amount so that the dummy pattern is not imaged during exposure.

Abstract: A method of code programming a mask read only memory (ROM) is disclosed. According to the method, a first photoresist layer is formed over word lines and a gate oxide layer of a substrate already having implanted bit lines. The first photoresist layer is patterned to develop pre-code openings over all of the memory cells, which correspond to intersecting word and bit lines. The first photoresist layer is then hardened using either a treatment implant or a treatment plasma. Subsequently, a second photoresist layer is formed over the first photoresist layer and patterned to develop real-code openings over memory cells which are actually to be coded with a logic “0” value. Each memory cell to be coded is then implanted with implants passing through the pre-code openings and the real code openings and into the memory cell.

Abstract: A spacer forming method for a biosensor that has a biosensor possessing a capillary sampling channel and electrical connecting tracks for the use of a specific portable meter. A pair of electrodes is printed on an insulating base plate to be the transducer of the electrochemical biosensor by means of the screen-printing technology. The advanced thick-film printing technology is employed to construct the spacer component of the sampling channel that precisely controls the volume of a sample solution. Therefore, the spacer forming method reduces the usage of adhesive that otherwise causes a serious problem during a continuous punching procedure. Furthermore, the embedded switch pad on the biosensor is introduced to be instead of a micro switch in a connector of the portable meter.
