In semiconductor manufacturing, a mask is sometimes called a reticle. [1] [2] In photolithography, several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set. A curvilinear photomask has patterns with curves, which is a departure from conventional photomasks which only have patterns ...
F 2 is used as a measurement of area for different parts of a semiconductor device, based on the feature size of a semiconductor manufacturing process. Many semiconductor devices are designed in sections called cells, and each cell represents a small part of the device such as a memory cell to store data.
The 10 μm process refers to the minimum size that could be reliably produced: the half-pitch, which is the distance between two 1-metal lanes, center to center, and the gate length of a transistor; those two values used to be identical in early nodes. The smallest transistors and other circuit elements on a chip made with this process were ...
A variety of reticles, each appropriate for one stage in the process, are contained in a rack in the reticle loader, usually located at the upper front of the stepper. Before the wafer is exposed a reticle is loaded onto the reticle stage by a robot, where it is also very precisely aligned. Since the same reticle can be used to expose many ...
Unlike electronic integration where silicon is the dominant material, system photonic integrated circuits have been fabricated from a variety of material systems, including electro-optic crystals such as lithium niobate, silica on silicon, silicon on insulator, various polymers, and semiconductor materials which are used to make semiconductor lasers such as GaAs and InP.

A 2.5D integrated circuit (2.5D IC) is an advanced packaging technique [1] that combines multiple integrated circuit dies in a single package [2] without stacking them into a three-dimensional integrated circuit (3D-IC) with through-silicon vias (TSVs). [3]
