RIR -Ruttonsha International Rectifier( Although i dont understand this sector but still tried my best to learn ,so if you find any mistake then please comment )
History
✍️international Rectifier (IR) was founded in the US in 1947 to make products predominantly for
power management. Mr. Ruttonsha obtained a license from IR to make the products in India, hence the name Ruttonsha International Rectifier
✍️Though it began in Mumbai, the facility was moved to Halol near Vadodara in Gujarat by around 1984. RIR was mainly focused on the low power segment within the power management devices.

✍️Meanwhile, after the passing away of Mr Ruttonsha, the founder of RIR, his successors also started an Export Oriented Unit (EOU) in the late 1990s. SPCO ( Current promotors) acquired Ruttonsha EOU in 2002 and later the parent company Ruttonsha in 2006.
✍️SPCO and Ruttonsha were focused on Silicon-based power devices until 2019; at that point, they felt Silicon had started reaching its technology limits, so they decided to get into compound semiconductors or, you may say, next-generation substrates.
✍️In the US, promotors acquired a Silicon Carbide (SiC) fab and started ViSiCon Power to focus on SiC-based products.

✍️So Now RIR is Having

✍️plan for SiC-based products is in three phases.
Phase 1: Making the SiC wafer. Since the full thickness of the wafer does not need to be completely pure,
they will start with a regular SiC wafer and, through epitaxial processes, deposit pure SiC to the required thickness on top of that. This itself gives us sellable products because many companies want to buy this "ready to make devices" SiC wafers.
Phase 2: This is building the fab that can do the device fabrication, and the output will be the processed wafers.
Phase 3: Dicing the devices from the processed wafers and packaging them.
✍️This is the order in which the process flow happens. However, after Phase 1,they are focusing on Phase 3
✍️The three phases together need an investment of about 175 to 200 crore INR, out of which Phase 2 is the more investment heavy phase requiring about 150 crore and
✍️Out of the total 175-200 crore needed, they have raised about 40-45% through loans .
