Soleil (age 8) is presented with two identical balls of clay. The experimenter rolls one ball into a long, thin shape; the other remains in its original ball form. Soleil is then asked if there is more clay in the ball or in the long, thin piece of clay. If Soleil answers the problem correctly but cannot use abstract reasoning yet, Soleil is most likely in which stage of Piaget’s cognitive developmental theory?

The amount of energy available increases as it is transferred to higher trophic levels.

_____________ resist when exposed to light, undergoes a reaction by which, the polymer bonds weaken to become more dissolvable in the development solutions.

Magnetic field and diamagnetic effect can be employed to separate particles such as red vs. white blood cells.

Surface acoustic wave transducers can be used to separate particles.

Misalignment of a rectangular shaped mask opening relative to the [110] direction of major flat of a (100) silicon wafer that results in a larger etched region.

The unit cell in a lattice is a segment representative of the entire lattice and the crystalline structure of a material.

One of the reasons that the (111) planes are normally etched slower than (100) planes is because (100) plane has more dangling bonds for atom at Si surface.

One of the key enabling processing techniques in bulk micromachining is the introduction of a sacrificial layer, which will be completed removed during the device final releasing process.

“When we talk about MEMS devices, we highlight the micro part of it. It means MEMS devices can be batch fabricated (mass production)”. However, MEMS devices have nothing in common in terms of fabrication methods when it compared with IC (integrated circuit) fabrication.
