Abstract: In accordance with the invention, a contaminated III-V semiconductor surface is cleaned by the sequential steps of exposure to hydrogen plasma, chemical etching in chlorine and annealing in vacuum. In a preferred embodiment, a semiconductor of the gallium arsenide family is subjected to hydrogen plasma in an ECR system for 20-120 minutes, then, without breaking vacuum, subjected to a C1 2  chemical etch at 250°C-450°C for 1-5 minutes. Again, without breaking vacuum, the semiconductor is annealed at 200°C-600°C for 5-15 minutes. To obtain good surface reconstruction, annealing preferably takes place at a temperature 300°C or above. The semiconductor surface thus processed is atomically smooth and sufficiently clean to permit regrowth of a high quality epitaxial layer.

Abstract: A structure and method for fabricating circuits which use field effect transistors (FETs), bipolar transistors, or BiCMOS (combined Bipolar/Complementary Metal Oxide Silicon structures), uses low temperature germanium gas flow to affect metals and alloys deposited in high aspect ratio structures including lines and vias. By using a germanium gas flow, germanium (Ge) will be introduced in a surface reaction which prevents voids and side seams and which also provides a passivating layer of CuGe. If a hard cap is needed for surface passivation or a wear-resistance application, the GeH₄ gas followed by WF₆ can be used to produce an in-situ hard cap of W x Ge y . Further, high aspect ratio vias/lines (aspect ratio of 3 or more) can be filled by utilizing low pressures and high temperatures (i.e., below 450 °C) without degrading the underlying metals.

A set of strong pullup elements (75) connected to the columns is conductive only after the hardware keyscan circuit (54) detects that a key (89) is depressed and disables the driving of the rows. Thus, pullup time and power consumption are minimized. The hardware keyscan circuit (54) also includes a data direction register (61) which has a shift control input terminal so that in response to a local state machine (64), the data direction register (61) acts as a shift register to sense the row with the depressed key (89), without intervention from a central processing unit (51).
