Patent EP-0471126-A2 (EP)
Inventor: HWANG STEPHEN
IPC: H01L21/8244
Filed: 1990-11-29
Abstract: An SRAM cell includes two cross coupled drive transistors, each having associated therewith an access transistor connected to bit and word lines, and a thin film transistor load connected to a voltage source. As the drive transistors are cross coupled, the left branch drive transistor is switched by the voltage at the drain of the right branch drive transistor, and the right branch drive transistor is switched by the voltage at the drain of the left branch drive transistor. The SRAM cell is laid out such that the left branch thin film transistor is gated by the gate of the right branch drive transistor, and the right branch thin film transistor is gated by the gate of the left branch drive transistor. Accordingly, when the left branch drive transistor is ON, for example, the left branch thin film transistor presents a high resistance to limit the standby current flowing through the left branch. At the same time, the right branch drive transistor is OFF and the right branch thin film transistor is ON. The ON right branch thin film transistor is capable of driving sufficient current to the right branch drive transistor so that the right branch drive transistor is not easily able to pull down its drain node, which contributes to cell stability.

Abstract: Es wird eine modifizierte amorphe Kieselsäure beschrieben, die abgesehen von gegebenenfalls vorhandenen üblichen Zusätzen aus 40 bis 85 Gew.% Kieselsäure und 60 bis 15 Gew.% Paraffin-, Silikon-, pflanzlichem Öl und/oder Ethylenglykol besteht. Die modifizierte amorphe Kieselsäure wird hergestellt, indem man abgesehen von gegebenenfalls vorhandenen üblichen Zusätzen Kieselsäure mit einer solchen Menge Paraffin-, Silikon-, pflanzlichem Öl und/oder Ethylenglykol zusammenbringt, daß der Gehalt der fertigen modifizierten Kieselsäure an Paraffin-, Silikon-, pflanzlichem Öl und/oder Ethylenglykol 60 bis 15 Gew.% beträgt. Die modifizierte amorphe Kieselsäure eignet sich als Antiblockingmittel, das in vorteilhafter Weise als Konzentrat (Masterbatch) hergestellt werden kann. Überraschenderweise erniedrigt sich der Schmelzindex bei der Herstellung eines derartigen Konzentrats kaum gegenüber dem Schmelzindex des Polyolefins, das die Basis des Konzentrats darstellt. Dadurch ist es möglich, große Mengen der modifizierten Kieselsäure in sehr homogener Verteilung in das Konzentrat einzuarbeiten. Dies wiederum wirkt sich günstig aus auf die Verwendung des Konzentrats bei der Folienherstellung. <IMAGE>

The size of the support stand is determined such that the quantity of heat conduction in a heat conduction passage from the thermal photodetector element to the mount is equal to a predetermined quantity. Thus, the photodetector is maintained within a predetermined temperature range.
