`mask-programmed read-only memory [ROM] A read—
`only memory in which a mask produces the metallizgd
`interconnection pattern corresponding to the desired per.
`manently stored program or data.
`mass The quantity of matter in a body. Mass is a measure
`of inertia and determines resistance to acceleration inde-
`pendently of gravitational force, whereas weight is the
`force exerted by a body under the influence of gravity at a
`particular location.
`muss conversion factor Atomic mass conversion factor.
`mass-energy equation The equation developed by Albert
`Einstein for interconversion of mass and energy, written as
`E :mcz, where E is the energy in ergs, m is mass in grams,
`and c is the velocity of light in centimeters per second.
`mass memory A large-capacity magnetic memory disk or
`memory system consisting of multiple parallel Winchester-
`style hard disks for mainframe computers or supercom-
`puters.
`mass migration Metallic erosion that Occurs when a high
`current density is passed through a conductor that has a
`small cross-sectional area, such as the conductors in inte-
`grated circuits.
`mass spectrograph A mass spectrometer that provides a
`permanent record of the mass spectrum lines of a material
`on a photographic plate.
`mass spectrometer A spectrometer that analyzes a sub-
`stance in terms of the ratios of mass to charge of its com—
`ponents. A gas or a compound in the vapor state is
`bombarded by electrons, and the resulting ions are acnel-
`erated and separated according to their tnass-to-charge
`ratios, in the most common type. combined electric and
`magnetic fields deflect the ions of the substance and focus
`each type in turn on an output electrode for detection and
`measurement. In another type, sorting of ions is based on
`the time of flight of the ions through a drift tube during
`acceleration by electric fields.

`Mars Global Surveyor
`
`Mars Global Surveyor A spacecraft that is to go into orbit
`around Mars and use a battery of six instruments to scan
`the planet‘s surface for a full Martian year (about two
`earth years),seeking evidence of past or present water and
`life forms.
`Mars Pathfinder Lander A spacecraft that will fly directly
`to Mars and land on its surface to transmit images of the
`Martian terrain with a colorTV camera. It will monitor the
`Martian weather and deploy a small roving unit that will
`explore the terrain and sample rocks and soil.
`maser [microwave amplification by stimulated emission] A
`microwave amplifier that amplifies by stimulating atoms or
`molecules to an unstable higher energy level. A microwave
`input signal interacts with the atoms or molecules to stimu-
`late the emission of excess energy at the same frequency
`and phase as the stimulating wave, thus providing coherent
`amplification at a wavelength detemtined by the dimen»
`sions of the cavity or resonant structure. The application of
`external energy required for amplification or oscillation is
`called pumping The radiated energy greatly exceeds the
`energy level of the pumping signal. There are three types:
`gas, solid state, and traveling wave. Ammonia atoms or
`molecules are the parametric material in beam-type gas
`maser oscillators. Solid-state masers depend on the elec-
`trons of parametric atoms or molecules. There are two- and
`three-level solid-state masers. Masers can function as low-
`noise preamplifiers for very weak signals in radio astron-
`omy or long-distance radar, and as time and frequency
`standards. The stimulated emission principles of thc maser
`apply in the visible light and infrared regions, where the
`equivalent device is the laser.

`mask 1. A transparent (glass or quartz) plate covered with
`opaque patterns that define the size and shape of inte-
`grated-circuit elements at one level of fabrication. Exam-
`ples include wells, emitters, gates, drains, and chamiels.
`Selected areas of a photoresist-coated wafer are exposed to
`ultraviolet light to define the areas to be etched. Opaque
`mask areas can be formed from deposited chrome, iron
`oxide, or silicon. As many as 20 successively registered
`masks might be used to make an IC.
`2. A transparent
`(glass or plastic) plate with opaque emulsion forming a
`stencil for defining conductors, pads, ground planes, and
`contacts in printed»circuit board manufacture. Light passing
`through the mask exposes the pattern onto a photoresist—
`coated circuit board. Exposed photoresist is chemically
`removed, and the pattern that remains defines the copper-
`clad areas to be removed by acid etch. See lithographic.

`sound is raised by the presence of another sound.The unit
