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.

The longitudinal strip is a stacked layer comprising a gate dielectric layer, a conductive layer and a cap layer. A buried bit line is formed in the substrate on each side of the longitudinal strip. The longitudinal strip is patterned to form a plurality of stacked blocks. Thereafter, a dielectric layer is formed over the substrate. The dielectric layer exposes the cap layer of the stacked blocks. Some cap layers of the stacked blocks are removed to expose the conductive layer underneath. A word line is formed over the dielectric layer to connect stacked blocks in the same row serially together.

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.

Abstract: Methods for making integrated circuit devices, such as high density memory devices and memory devices exhibiting dual bits per cell, include forming multiple oxide fences on a semiconductor substrate between multiple polybars. The oxide fences create a hole pre-code pattern that facilitates ion implantation into trenches disposed between the polybars. The holes, or voids, formed by the oxide fences provide greater control of the critical dimension of ion implantation, for example, the critical dimension of the trench sidewalls. Semiconductor devices used in the manufacture of memory devices include the oxide fences during the manufacturing process.

Abstract: A phase shifting mask repair process is described. The process uses an etching gas or a hydrofluoric acid solution to etch the quartz substrate and the characteristics of the phase shifter layer being only slightly etched when clean with a NH3/H2O2/H2O2 solution to calculate and adjust the respective processing time accordingly. As a result, the phase difference between the quartz substrate and the MoSiON phase shifter layer stays relatively the same before and after the repair process.

Abstract: In accordance with the present invention, a method is provided for shrinking critical dimension in semiconductor processes. This method comprises a step of performing an over-exposure process to a photosensitive layer to form a patterned photosensitive layer on a substrate by using a patterned reticle. Due to the unexposed region of the photosensitive layer being diminished by over-exposure the critical dimension is shrunk. Then, a sacrificial layer is applied for the purpose of pattern reverse-transferring. Next, the patterned photosensitive layer is removed such that the pattern is transferred to the sacrificial layer with a shrunk critical dimension. In cooperation of the present exposure technology with the present invention, the shrinkage of a critical dimension is accomplished, for example, using an I-line exposure light source in a critical dimension of 0.25 &mgr;m process, or using a deep UV (ultraviolet) exposure light source in a critical dimension of 0.13 &mgr;m process.

Abstract: A method for forming a protrusive alignment-mark in semiconductor devices is disclosed. A photolithography process is performed to form a photoresist layer on a substrate wherein the substrate has an element region and an alignment region, and the photoresist layer has an element photoresist region and an alignment photoresist region. Afterwards, a first dielectric layer is deposited on the element photoresist region and the alignment photoresist region. The excess portion of first dielectric layer above the photoresist layer is removed such that the photoresist layer is coplanar with the first dielectric layer and thus the photoresist layer is exposed. The photoresist layer on the element region and said alignment region is stripped to form a protrusive alignment-mark on the alignment region.

Abstract: A method of fabricating a gate is described. A first dielectric layer having a first opening is formed on a substrate. A gate dielectric layer is formed in the opening. A lower portion of a floating gate is formed on the gate dielectric layer. A source/drain region is formed in the substrate beside the lower portion of the floating gate. A conductive layer is formed on the first dielectric layer to completely fill the first opening. The conductive layer is patterned to form a second opening in the conductive layer. The second opening is above the first opening and does not expose the first dielectric layer. The second opening has a tapered sidewall and a predetermined depth. A mask layer is formed to cover the conductive layer and fill the second opening. The mask layer outside the second opening is removed to expose the conductive layer. A portion of the mask layer is removed to leave a first etching mask layer in the second opening. An anisotropic etching process using the first etching mask layer as a mask is performed to etch the conductive layer. An upper portion of the floating gate is formed. The first dielectric layer is exposed. The first etching mask is removed. Thereafter, a dielectric layer between gates and a control gate is formed over the floating gate.
