Patent TW-434096-B (TW)
Title: Wafer polishing apparatus
Inventor: NUMOTO MINORU
IPC: B24B37/30
Filed: 1998-08-07
Granted: 2001-05-16
Abstract: The first air guide groove is formed at the bottom of a carrier along the inner circumference of a circle whose radius corresponds to the maximum radius of a wafer. The air is supplied to the outer periphery of the wafer through the first air guide groove to form a pressure air layer between the carrier and the wafer. The formation of the pressure air layer makes the air pressure applied to the wafer uniform on the entire surface of the wafer, and thus, the wafer can be polished under a uniform pressure force. The second air guide groove is formed along the inner circumference of a circle whose radius corresponds to the minimum radius of the wafer, and therefore, the wafer with an orientation flat or notch can be polished under a uniform pressure force.

Granted: 2001-02-01
Abstract: In the manufacture of integrated circuits with an embedded non-volatile memory, it is known to first provide the greater part of the memory and subsequently provide the CMOS logic in a second series of steps of a standard CMOS process. By virtue of this separation of process steps, it is possible to optimize the non-volatile memory substantially without degrading the logic. According to the invention, this process is further optimized in that, particularly for the periphery of the memory, and simultaneously with the memory transistors (21, 24, 27), transistors are manufactured which can cope with a higher voltage than the transistors of the logic. In the case of an EEPROM, each cell of the memory is provided with such a high-voltage transistor as a selection transistor (22, 24). Apart from the n-well implantation (5), high-voltage transistors of the p-channel are largely manufactured by means of the same process steps as the p-channel transistors in the logic, so that the number of process steps remains limited. By adding a single mask, the circuit may also be provided with a Flash or an OTP (One Time Programmable) memory.
