    摘要: In a method of planarizing a semiconductor wafer having aluminum interconnect tracks formed thereon, a method is disclosed for applying inorganic spin-on glass which comprises applying the spin-on glass to the wafer in a coating and spinning chamber in a moisture-free environment, transferring the wafer in a moisture-free environment to a curing station, curing the spin-on glass at a temperature in the range of about 80.degree. to 250.degree. C. in the moisture-free environment at the curing station, and returning the wafers to the coating and spinning chamber. The above steps are repeated until a sufficient film thickness has been achieved without in the interim exposing the wafer to moisture conditions such that reverse hydrolysis si minimized during the planarization process. In this way crack-free inorganic SOG films can be produced.

    摘要: A method of applying a spin-on glass layer to a substrate is disclosed characterized in that the spin-on glass is applied as a plurality of contiguous thin layers that together form a composite layer. Each thin layer is cured prior to the application of the next layer at a temperature of at least about 300.degree. C., preferably 350.degree. C., for a time sufficient to permit catalyst connection and substantially eliminate volatile residual solvents contained therein. In this way cracking in organic SOGs can be substantially eliminated, and beneficial results can also be achieved with quasi-organic SOGs.

    摘要: A method of making optical quality films is described. A silica film is deposited on a wafer by PECVD (Plasma Enhanced Chemical Vapor Deposition). The deposited film is then subjected to a first heat treatment to reduce optical absorption, wafer warp, and compressive stress. A second film is deposited. This step is then followed by a second heat treatment to reduce optical absorption, wafer warp and tensile stress. The two heat treatments have similar temperature profiles.

    摘要: A process for making an integrated circuit is described wherein sequence of mask steps is applied to a substrate or epitaxial layer of p-type material. The sequence consists of sixteen specific mask steps that permit a variety of bipolar/CMOS/DMOS devices to be fabricated. The mask steps include (1) forming at least one N-well in the p-type material, (2) forming an active region, forming a p-type field region, (4) forming a gate oxide, (5) carrying out a p-type implantation, (6) forming polysilicon gate regions, (7) forming a p-base region, (8) forming a N-extended region, (9) forming a p-top region, 10) carrying out an N+ implant, (11) carrying out a P+ implant, (12) forming contacts, (13) depositing a metal layer, (14) forming vias, (15) depositing a metal layer therethrough, and (16) forming a passivation layer. Up to any three of mask steps (4), (7), (8), and (9) may be omitted depending on the type of integrated circuit.
