Abstract: Integrated circuits, the key components in thousands of electronic and computer products, are generally built layer by layer on a silicon substrate. One common technique for forming layers is called chemical-vapor deposition (CVD.) Conventional CVD systems not only form layers that have non-uniform thickness, but also have large chambers that make the CVD process wasteful and slow. Accordingly, the inventor devised new CVD systems, methods, and apparatuses. One exemplary CVD system includes an outer chamber, a substrate holder, and a unique gas-distribution fixture. The fixture includes a gas-distribution surface having holes for dispensing a gas and a gas-confinement member that engages or cooperates with the substrate holder to form an inner chamber within the outer chamber. The inner chamber has a smaller volume than the outer chamber, which not only facilitates depositions of more uniform thickness, but also saves gas and speeds up the deposition process.

Abstract: An internal combustion engine (10) for a vehicle comprises a fuel injector (12) which supplies fuel to a combustion chamber formed in a piston (1), and an oil pan which stores engine oil below the piston (1). With regard to a phenomenon whereby the engine oil is diluted with the fuel injected by the fuel injector (12), a controller (90) determines whether or not the engine oil needs to be regenerated (S13). When the engine oil needs to be regenerated, the controller (90) switches a cooling water path in the engine (10) by controlling an electrically controlled thermostat (74), and raises the temperature of the engine oil over a predetermined time period (S15, S17). As a result of this temperature increase, the fuel in the engine oil is vaporized, thereby reducing the dilution ratio of the engine oil, and thus the engine oil is regenerated.
