The thickness of the depletion region or depletion layer (and there are other terms) varies as the design of the semiconductor. The layers in a semiconductor are "grown" (usually by deposition), and this can be controlled. The typical depletion region thickness in an "average" junction diode is about a micron, or 10-6 meters. Junction "construction" presents major engineering considerations to those who design and make semiconductors as there are many different kinds. A link is provided to the section on the width of depletion regions in the Wikipedia article on that topic.
When a diode is made (ie. NO current pass through the diode) then depletion layer is form between N & P.

p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
The motto of Cypress Semiconductor is 'Perform'.
In a semiconductor, the charge concentrates at the bounds of the space charge region(depletion layer).

Width of depletion layer is given by x = (2*ebsylum*Vb).5/(qN) x = width Vb = potential barrier q = charge of electron N = doping concentration. Thus increase in doping will reduce width of depletion layer.
Yes it does. It is because depletion takes place in winters only.
in correct sense it is not the layer but the region around the metallurgical junction which is depleted of charge carriers .in this region an internal electric field exist which counter balance the diffusion of electron and hole around the junction . basically the main reason for the formation of depletion region is the concentration gradient across metallurgical junction of p-n semiconductor.

on forward biasing width of the depletion layer decreases whereas on reverse biasing the width of depletion layer increases.
Depletion layer is thin now. It is called depletion when the concentration is below 380 Dobson Units.
Ozone layer depletion has no significance. It is a deadly phenomenon.
Ozone layer depletion is the depletion of ozone. It has very bad affect on environment,
No it is not nature friendly. Depletion of ozone layer is harmful.
The depletion layer is thin yet. But if we continue using CFC, it will be more.
