Question: Which is more difficult, a wet or dry pass?

Wet oxidation is preferred to dry oxidation for growing thick oxides, because of the higher growth rate.
However, fast oxidation leaves more dangling bonds at the silicon interface, which produce quantum states for electrons and allow current to leak along the interface.
(This is called a "dirty" interface.)
Wet oxidation also yields a lower-density oxide, with lower dielectric strength.
The long time required to grow a thick oxide in dry oxidation makes this process impractical.
Thick oxides are usually grown with a long wet oxidation bracketed by short dry ones (a "dry-wet-dry" cycle).
The beginning and ending dry oxidations produce films of high-quality oxide at the outer and inner surfaces of the oxide layer, respectively.
Mobile metal ions can degrade performance of MOSFETs (sodium is of particular concern).
However, chlorine can immobilize sodium by forming sodium chloride.
Chlorine is often introduced by adding hydrogen chloride or trichloroethylene to the oxidizing medium.
Its presence also increases the rate of oxidation. 
In the United States, a moist county is a county in between a "dry county" (where the sale of alcoholic beverages is prohibited) and a "wet county" (where alcohol is sold).
The term is typically used for any county that allows alcohol to be sold in certain situations, but has limitations on alcohol sales that a normal "wet" county would not have.
Some historically "dry" counties are switching to this system to avoid losing money to businesses in other counties, but do not wish to become completely "wet."
The term in itself does not have any specific meaning, just that the county is not completely "wet" but is not "dry", either.
The terms are applicable in states in which each county makes its own rules on alcohol sales.
A "dry" county that contains one or more "wet" cities is typically called "moist". 
A "wet single-point" nitrous system introduces the fuel and nitrous together, causing the upper intake manifold to become wet with fuel.
In carbureted applications, this is typically accomplished with a spraybar plate mounted between the carburetor base and the intake manifold, while cars fitted with electronic fuel injection often use a plate mounted between the manifold and the base of the throttle body, or a single nozzle mounted in the intake tract.
However, most makes of nitrous systems combined with unsuitable intake designs, often result in distribution problems and/or intake backfires.
Dry-flow intakes are designed to contain only air, which will travel through smaller pipes and tighter turns with less pressure, whereas wet-flow intakes are designed to contain a mixture of fuel and air.
Wet nitrous systems tend to produce more power than "dry" systems, but in some cases can be more expensive and difficult to install.
This is due to the process of discovering, cutting, and tapping into the fuel delivery line, many of which are high high pressure (20-40PSI.
)A wet nozzle differs in the way that it takes in both nitrous and fuel which are metered by jets to create a perfect or proper air-fuel ratio (AFR).
Proper atomisation of the fuel and nitrous will ensure consistent power gains.
Newer wet nitrous kits on domestic cars have become increasingly easy to install by pulling fuel via the schrader valve on the fuel rail, which is normally designated as a fuel test port.
It makes plumbing and using a wet nitrous kit much simpler. 
Aircraft leases are a number of types of leases used by airlines and other aircraft operators.
Airlines lease aircraft from other airlines or leasing companies for two main reasons; to operate aircraft without the financial burden of buying them, and to provide temporary increase in capacity.
The industry has two main leasing types, wet leasing which is normally used for short term leasing and dry leasing which is more normal for the longer term leases.
The industry also uses combinations of wet and dry when for example the aircraft is wet-leased to establish new services then as the airlines flight or cabin crews become trained they can be switched to a dry lease. 
A dry loop is an unconditioned leased pair of telephone line from a telephone company.
The pair does not provide dial tone or battery (continuous electric potential), as opposed to a "wet pair", a line usually without dial tone but with battery.
A dry pair was originally used with a security system but more recently may also be used with digital subscriber line (DSL) service or an Ethernet extender to connect two locations, as opposed to a costlier means such as a Frame Relay.
The pair in many cases goes through the local telephone exchange.
"Wet pair" naming comes from the battery used to sustain the loop, which was made from wet cells.
The wet pair was the one drowned into the battery.
Many carriers market dry loops to independent DSL providers as a BANA for Basic Analog Loop or in some locales PANA for plain analog loop, OPX (Off Premise Extension) line, Paging Circuit, or finally LADS (Local Area Data Service).
