PPA (Purchase and Procurement Agent): The required purchases for raw materials necessary tools and etc. are managed by this agent.
RTSA (Return to Supplier Agent): If the return of the purchased raw materials is needed, this agent sends a request of return to RFCA and pursues the process to do this.
- OFA, COA and SLCA managed the operation of the supply chain and due to this close relation and adequate information flow, the rejection and returning of the sold or bought goods and materials were decreased
- Decreased transportation cost: the company planned to choose the best supplier in quality and cost and also due to decrease of the returned materials and goods, the transportation cost was reduced

Table 1 illustrated the properties of these materials.
The electrical mechanism of the compound materials involves mutual contact of the electric powder in the materials resulting in the formation of electrical channels.
Uniform mixtures mean all filler materials supposed to be wetted by matrix.

Composite materials are formed from two or more materials producing properties that could not be obtained from any one material.
One of the constituent materials acts as the matrix and at least one other constituent material acts as the reinforcement in the composite.

The operation principle of bimaterial uncooled micro-cantilever IR sensors is based on the resonant frequency shift of bimaterial beams which composes two materials with different coefficient of thermal expansion (CTE) while absorbing the IR energy.
Then, pattern and etch PSG, SiO2 and polysilicon till all materials covering the IC circuits’ passivation were removed.
