摘要： An optical device includes a light-transmitting medium on a base. The light-transmitting medium at least partially defines a free propagation region through which light signals travel. A reflective grating is positioned such that light signals can travel through the free propagation region and be received by the optical grating. The optical grating is configured to reflect the received light signal back into the free propagation region. The optical grating reflects the light signals such that light signals associated with different wavelengths separate as the light signals travel through the free propagation region. The portion of the light-transmitting medium that defines the free propagation region has a facet through with the light signals are transmitted. The grating includes a buffer layer between the facet and a reflecting layer that is configured to reflect the light signals received by the grating.

摘要： Although the spacers are formed on the sidewalls of gate electrode and words lines via the same steps of deposition and etch-back processes, only the spacers disposed at the sidewalls of the gate electrode are practical for fabricating peripheral devices with LDD structure, and such fabrication is impractical in the memory cell region. On the contrary, the region beneath the spacers disposed at the sidewalls of word lines will become the path through which leakage current flows. The present invention makes use a shielding layer to cover the second active region as a masking, and then removes the spacers disposed at the sidewalls of word lines. Afterwards, isolating regions are formed through one implantation procedure to thereby decrease leakage current and simplify the process flow.

摘要： A fabricating method for a DRAM capacitor is provided. A DRAM is formed on a substrate, wherein a transistor has been formed. A first oxide layer is formed over the substrate and a contact window is formed on the first oxide layer to expose a source region of the transistor. Then, a bit line is formed in the contact window, wherein the bit line is connected to the source region of the transistor. A second oxide layer is formed on the bit line and the first oxide layer. Then, a third oxide layer is formed on the second oxide layer. A second contact window is further defined to expose a drain region of the transistor, wherein the drain region has a native oxide layer formed on it. Next, a first polysilicon film is formed on the exposed drain region of the second contact window. A high dosage implantation is used to remove the native oxide layer. Then, a second polysilicon layer is formed over the substrate. Finally, the finishing process followed is performed to complete the fabrication of a DRAM capacitor.
