(디엔에프)Exploring Semiconductor Materials: DPT, High-k, and Low-k

 
  Hey there ! I'm the head honcho over at 디엔에프(DNF). Recently, 솔브레인(Solbrain) has taken us under their wing as a subsidiary, but rest assured, we're still in business and doing our thing. Let's dive into what we're all about and what we've got in store. 
 
  Our gig revolves around crafting materials used in manufacturing semiconductors, specifically DPT(Double Patterning Tech), High-k, and Low-k. Let's break down our product lineup. 
 
  First up, DPT, which stands for Double Patterning Tech. It essentially involves executing patterning twice. You might be thinking, "Why not just pattern once?" Well, that's a valid point, but here's the catch - you only get to pattern once if you have EUV(Extreme Ultra Violet) machinery at your disposal. If you don't, DPT steps in. It's a straightforward process - just pattern it on photoresists twice, and you'll end up with micro-thin patterns that rival EUV. 
 
 
  Now, onto our other materials, High-k and Low-k. These names both share the letter 'k,' which signifies how much they can attract electrons. High-k, as the name suggests, attracts more electrons, and low-k, on the flip side, attracts fewer. Let's see how they come into play. 
 
  High-k materials come in handy in DRAM(Dynamic Random Access Memory). As chips keep shrinking in size, capacitors have to follow suit, and they become so tiny that they struggle to store enough electrons. That's where high-k materials come to the rescue. They're great at attracting electrons, making them ideal for DRAM. 
 
  Now, let's talk about low-k. As mentioned earlier, low-k materials attract fewer electrons, making them perfect for insulators. This is where they find their place in 3D NAND. In 3D NAND, chips're stacked layer upon layer. With all those layers in close proximity, you run the risk of electromagnetic interference. That's where low-k materials step in as insulators, shielding against those pesky electromagnetic disturbances. 
 
  Whether it's chips stacking up like a tower in 3D NAND or the world of HBM(High Bandwidth Memory) where DRAM is stacked, both high-k and low-k materials play pivotal roles in the semiconductor industry. So, that's the scoop on what we're all about.

  Hey folks ! I'm the big cheese over at 디엔에프. Yeah, recently 솔브레인's taken our company over as their subsidary. But, we're still doing the business, so we're gonna break down what we do and what will do. 
 
  Our gig is all about crafting materials for manufacturing semiconductors. Those are DPT(Double Patterning Tech), High-k, Low-k. Let's dive into our business products. 
 
  First, DPT. DPT stands for Double Patterning Tech. It basically execute patterning twice. You seem like you only know patterning execute once. Yeah, you're right but only if you have EUV(Extreme Ultra Violet) machinery to pattern. If you don't have it? Then you should use DPT. DPT is very simple. Just pattern it on photo resists twice so that you would get micro-thin patterns as if you used EUV. 
 
  Let's move to the next material, high-k and low-k. These two names have 'k' in common. K means how much you can attract electrons. So, it can mean high-k attract more electrons. On the ohter hands, low-k attract less. Then, we can apply these materials to useful stuffs. High-k attracts electrons in DRAM(Dynamic Random Access Memory). As chips get smaller and smaller, capacitors've become so tiny that it can't store electrons as it needs. So, DRAM needed some materials affordable to attract electrons. Here is where high-k came in play. Second, low-k. Like I said, low-k attracts less electrons. So, it will be really good if it is used for insulators. So, low-k goes with 3D NAND. 3D NAND is the way NANDs are added up with a layer onto a layer. If they keep stacking up, each layer might cause electromagnetic interference. So, here is where low-k comes in. Low-k can be insulator between layers to shield electromagnetics. 
 
  As chips is added up to chips like 3D NAND and HBM(High Bandwidth Memory) where DRAM is stacked up, either, high-k and low-k will play a crucial role in semiconductor industry.
