    摘要: A method of making bipolar and MOS devices simultaneously using a single fabrication process. In one embodiment of the invention, a silicon substrate is divided into bipolar and MOS regions. A thin layer of gate oxide, having a thickness in the range of from approximately 150 angstroms to 300 angstroms, is thermally grown on the silicon substrate. A thin layer of polycrystalline silicon, having a thickness in the range of from approximately 500 angstroms to 1000 angstroms is deposited on the gate oxide layer to protect the gate oxide layer during subsequent processing. Both the thin polysilicon layer and the gate oxide layer are removed from the bipolar region where the emitter is to be formed. To maintain the integrity of the gate oxide layer during etching, a photoresist mask used during the polysilicon etch is retained during the gate oxide etch, and the gate oxide is etched in a buffered oxide solution. A thick layer of polysilicon then is deposited on the bipolar and MOS regions of the silicon substrate, and the substrate is masked and etched for forming the emitter and gates of the bipolar and MOS devices, respectively.

    摘要: An optically-controlled shunt (OCS) circuit includes a switch and a light sampler. The light sampler is coupled to the switch and is configured to sample light at a photovoltaic (PV) cell corresponding to the OCS circuit and to turn on the switch when the sampled light comprises insufficient light for the PV cell. The light sampler may also be configured to turn off the switch when the sampled light comprises sufficient light for the PV cell. The light sampler may further be configured to partially turn on the switch when the sampled light comprises adequate light for the PV cell and to turn off the switch when the sampled light comprises full light for the PV cell. The switch could include a transistor, and the light sampler could include a photodiode.

    摘要: A trench which has walls intersecting a surface of a semiconductor substrate and an oxidation/diffusion barrier layer lining the walls is disclosed. The oxidation/diffusion barrier extends over the edges of the trench to prevent, for example, stress defects in the trench corners and vertical bird's beak formation within the trench. A filler material such as polysilicon is deposited within the trench followed by the deposition of a planarizing layer over the trench. After heat is applied, the planarizing layer flows to form a planarized layer over the trench. Using high pressure and phosphosilicate glass for the planarizing layer, the planarizing layer flows appropriately at low temperatures for short times.

    摘要: A process for preparing a light-sensitive integrated circuit (IC) for packaging that provides a reduced exposure of the light-sensitive IC to light. The process includes providing a semiconductor substrate (e.g., a silicon wafer) with a plurality of light-sensitive ICs formed in/on its upper surface. The lower surface is optionally coated with opaque material. Next, the semiconductor substrate is diced to form individual light-sensitive ICs, each of which has a semiconductor substrate lower surface and semiconductor substrate lateral edges. The semiconductor substrate lateral edges (and optionally backside) are then spray coated with an opaque material (e.g., opaque ink) to form an opaque layer covering the semiconductor substrate lateral edges. The opaque layer prevents light from entering the semiconductor substrate through the lateral edges and interfering with the operation of the light-sensitive IC. The inventive process is simple and inexpensive, employing, for example, piezoelectric injectors to spray coat opaque ink on the semiconductor substrate lateral edges as the individual ICs are conveyed through a pass-through. In addition, processes according to the present invention are independent of the techniques used to manufacture the light-sensitive ICs and, therefore, provide for increased packaging process flexibility and economy.
