South Korea's largest company has been grappling with a historic plunge in memory prices as consumers cut back on gadget purchases amid soaring interest rates and inflation. Inventories have piled up, forcing double-digit price declines that have exacerbated losses.   The business environment deteriorated significantly in the fourth quarter as demand weakened due to the global economic slowdown," the company said in a press release Tuesday, adding that in the semiconductor business, earnings are expected to fall by a quarter in the first quarter as plant utilization declined.   The world's largest memory chip maker, which supplies displays and semiconductors for Apple's iPhone, said it sees "a potential recovery in mobile demand in the second half of the year" as customers seek gadgets with more storage space. The Galaxy device maker said smartphone market demand could contract in 2023, dragged down by mass-market handsets.   Profit at Samsung's key chip

From a professional point of view, the production process of a chip is extremely complicated and tedious. But in terms of the complete IC industry chain, it is mainly divided into four parts: IC design → IC manufacturing → packaging → testing.   Chip fabrication process.   I. Chip design   Chip belongs to the small size, but great high precision products. To make a chip, design is the first link. The design needs to be done with the help of EDA tools and some IP cores, and finally made into the chip design blueprint needed for processing.   II . sand-silicon separation   All semiconductor processes start with a grain of sand. Because the silicon contained in the sand is the raw material needed to produce the silicon wafer, the "foundation" of the chip. So our first step is to separate the silicon from the sand.     III . silicon purification   After the silicon is separated out, the rest of the material is discarded. The silicon is purified in several steps to achieve the qua

  Before we clarify the semiconductor chip, we should first understand two points. One is what a semiconductor is, and the other is what a chip is.   Semiconductor   semiconductor, a material with conductivity between insulator and conductor at room temperature. People usually call materials with poor conductivity, such as coal, artificial crystals, amber, ceramics, etc., insulators. And the conductivity of the better metals such as gold, silver, copper, iron, tin, aluminum, etc. called conductors. Compared with conductors and insulators, the discovery of semiconductor materials is the most recent, until the 1930s, when the material purification technology improved, the semiconductor only received the attention of the industry. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., while silicon is the most influential of the various semiconductor materials in terms of commercial applications.   Chip   A chip, also known as a microchip, integrated circuit, o
